Hi All-
Pre-TL;DR: Got rooted S4. NOT USING A DLINK ROUTER. All wifi networks disappear and reappear 'randomly'.
So I got my S4 from Verizon on Friday the 24th. I set it up and went on my way. About two days after I got it I noticed 'slow' download while on the wifi. Didn't matter what I was doing; google play, downloading a game's extra data, or even just sitting there doing nothing. As I looked into it I found that my wifi connection was dropping. I'm not talking about disconnect and reconnect, but wifi in general would drop. I verified this while sitting in my living room. I live in an apartment and there are a lot of neighbors with wifi. While looking at the available wifi networks I noticed every few seconds ALL of the available networks would disappear (showing only my saved networks). I used a wifi analyzer and changed my wifi channel to an unused channel, checked for firmware updates (both router and phone), but nothing changed. On Tuesday I started work after the holidays and decided to test the wifi on my companies guest wifi. I was seeing the same stuff happening at work. I don't think it's my router(s) because all wifi goes away, not just the specific wireless network. I have the stock S4 that has been rooted using open1your1eyes0's guide
[GUIDE] Root for Verizon Galaxy S4 ***Updated 5/27 - 2:30 AM***, however I noticed this before I rooted it. Is anyone else having this problem? I'm about to take it to Verizon on Thursday.

I experienced this problem on Saturday when I got the phone-Called Verizon and was transferred to Samsung-they told me this is a known issue in the phone and it will require an antenna swap to fix. Apparently they have fixed the phones they are manufacturing now, however the ones which were initially released all have this problem.
Vzw has been no help at all in resolving this, and pretty much have told me "too bad, so sad". Really crappy of them.

Nghthawk and Fleury, I was so happy to see your posts!!! So it's not just a firmware issue!!!
I have a non-rooted S4 and have the same experience. I was with T-Mobile for a week before I transferred to Verizon and had the exact issue there. (I have a co-worker who has a Sprint S4 that doesn't have this problem.) I have this issue both on my home router (Linksys) and at work (Motorola). Previously, I had an S2 and never saw this issue once, neither at home nor at work. I also spoke to Verizon who told me to talk to Samsung. Samsung (via email) has had me try all kinds of crazy manual WiFi settings - none of which work - or are at all practical...
I'm still within my first 14 days of signing with Verizon, so I can still jump ship to get rid of this phone. I'd really rather not spend another __ hours setting up another one, though.
Perhaps you could help me with a bunch of questions I have - please... I really need help with this...
1. Who told you that the antenna needs to be replaced - Samsung or Verizon?
2. Is that documented somewhere that you know of?
3. Is either Verizon or Samsung going to cover the antenna swap?
4. Who / when is supposed to do that for you?
5. What do you suggest I do in my situation (e.g. being within the first 14 days)?
6. If it's an antenna issue, would that affect voice calls (quality / dropping), as well?
Thanks so much!
Eliezer
I will try to answer your questions as best as I can...
1. Who told you that the antenna needs to be replaced - Samsung or Verizon?-Samsung repair rep
2. Is that documented somewhere that you know of?-I'm sure Samsung has it in writing, Verizon is still in denial-having talked to their executive offices today-to which they are clueless and a waste of time
3. Is either Verizon or Samsung going to cover the antenna swap? Yes!
4. Who / when is supposed to do that for you? Samsung told me to send it now, however I am traveling and can't do that at the moment
5. What do you suggest I do in my situation (e.g. being within the first 14 days)? I would keep the phone, they will get it fixed, they don't really have a choice, approx sales are around 80 million units-they can't just ignore it-plus we are going to be the first to get aws spectrum...
6. If it's an antenna issue, would that affect voice calls (quality / dropping), as well? I have no problems with call quality, in fact, it is far better than my Galaxy Nexus which I traded in to get this. I have had 4G also act up to where it just freezes and fails to deliver internet, even though I will show 3-4 bars as well as the 4G lit up....So I believe it seems to only effect data.

It would be useful for those of us still on the sidelines if we can determine if we are getting a fixed version or one with this problem still.
This is one of the reasons I didn't jump in yet - to wait out any early production issues. Well, and still hoping for a 32 or 64gb version.
Interesting. I have a lot of the same issues. My WiFi is so bad I can't see any other WiFi networks on my device from my house where my other devices see 5 to 6. If I go into my daughters room my WiFi pretty much drops completely every time.
I just got off the phone with Samsung tier two / advanced tech support. He told me that my phone was manufactured May 15th... If a two week old phone has the problem, I cannot imagine the "new" ones don't also... He said they have no known issues submitted by Verizon for WiFi connectivity of the S4. Due the fact that it can connect to WiFi, he didn't think it sounded like a hardware issue. He suggested testing by taking the password off my router and seeing how it holds the signal. He said if it was able to maintain a connection like that, it must either be the router firmware or phone software issue.
Verizon said they could swap it with a new one for me - but there's no guarantee (or reason to think) that the same thing won't happen with that new one. And the option of sending it to Samsung and not having it for 11-12 business days isn't very appealing, either...
Not so happy about this...
Eliezer
you do know that the WiFi isse with DLink routers (DIR-655 and DIR-855) is not restricted to only those routers right? It does exist with other brand routers from whats been written about it.
Point being i have a DIR-655 router and had the connect drop connect drop issue and all I did was uncheck the WMM option and rebooted my router and its rock solid. WMM is kind of pointless, 95% of ppl can't even see a difference using it. I don't even think any of the public access points i've run into even have that enabled either.
If it's just your home wifi your having an issue with, turn off WMM in the router settings if you haven't already
Any updates about this? I'm experiencing wifi issues with my S4 where the signal I get on wifi is just horrible. Finally went into work today where we have an open wifi network on the entire campus, and I can't even get 2 bars of wifi from my desk, where my Galaxy Nexus would get 4. When it does connect, it's horribly slow. This has got to be a hardware issue. I may bring it back to Verizon, but I'm wondering if they will even believe me and swap the device.
Well, since I originally posted on this thread - and had commented that I saw this issue on both Verizon and T-Mobile - using both Motorola and Linksys routers --- I've switched to AT&T. I got one of their S4s and have had rock-solid WiFi connectivity with those same two routers ever since...
Not sure what to say...
I experienced my WiFi dropping like that once... how ever.. never again... really weird.. I have better Wifi then I did on my last phone.

Which carrier are you on?
Just compared to my friend's S4. With the two S4's sitting next to each other on my desk, he gets 4 bars of wifi at -46 dbm in Network Signal Info. I get 1 bar, and -88dbm! I walked directly the nearest ceiling mounted access point and my signal went up to -71dbm while he went to -40. So yea I definitely have some issues.

Are you able to change the title of this thread to include "Samsung Verified Issue" or something to that effect so that it will be more noticeable for others?

Not from what I can tell. I can edit the post, but I think a mod has to edit the title.
Update tho to my op:
After a factory reset and a re-root I noticed that this issue had stopped. It happened one more time after that, however, after a reboot it was fine again. I have yet to run into the problem again. This leads me to believe that there is a software issue (would also make sense why only Verizon phones seem to be affected) and not a hardware issue. I heard that google is going to release a 'clean' version of the S4 rom when they launch their carrier-less S4. I may just wait till that phone is released and flash that and see what happens.
I'm flashing mine to stock and doing a factory reset right now. Hoping it fixes the issue for now.

I wanted to add my own experience. I have a Verizon Galaxy S4 -- SCH-I545. I managed to fix the disconnection problem by using a static IP address on the phone side since the work router serves up the same one to my device every time, so I'm not causing collisions (and I don't have control of the router at work). I was getting 'failed to get IP address' messages when the connection dropped. See here:
http://forum.xda-developers.com/showpost.php?p=42172004&postcount=29
However, reading other posts about the antenna issue, I'm starting to think that it might just be that. I'm about 20 feet equidistant from 2 wireless routers at work, and using the *#197328640 hidden menu, then Menu button, then WiFi, my RSSI goes from -68 to -74 and goes up to about -52 to -55 when I'm about 3 feet from the AP I'm associated with. Does that seem low? According to what I've googled it seems like it is low...
---
And to think I was about to give up on contacting Samsung because they refused to acknowledge my Bluetooth issue here:
http://forum.xda-developers.com/showthread.php?t=2304828
With the BT issue I've done extensive troubleshooting and pretty sure it's not a software issue (at least not other apk's interfering) but possibly the bluetooth implementation or drivers itself.
:sigh: Now I'm going to have to test with the other S4 to see I get the same WiFi signal strength, at least at home, anyway.
So update for me, took mine to Verizon and they swapped it out. This one gets a great wifi signal.

Judging by your earlier numbers mine is fine. I compared it to an S3 and another Verizon S4 and both have about the same RSSI +/ 5 of each other at the same point at home... so the issue I'm facing is probably just related to the router at work I have no control over.
So, I just purchased a MediaPad Honor X1 (3G Only model 7D-501u). My carrier is T-Mobile and I am located in a refarmed/modernized area (Phoenix, AZ). Unfortunately, my MediaPad is not functioning on T-Mobile. I get a 3G signal (and even H+), but cannot get any internet data. I have tried all the APNs (epc.tmobile.com, fast.t-mobile.com, and all recommended combinations in between). But still, no data! I have mobile data enabled, tried both network mode=3G and 3G preferred, tried updating stock firmware to Android 4.4, then back again (couldn't deal with the large font size), still nothing. Voice calls are very inconsistent, most of the time failing before a connection is even made. I tried 3 different SIM chips, and even a brand new one that T-Mobile provided for me, no go.... I have a call into tech support and waiting for some assistance (not that they can help me at this point).
Phone/internet works on 2G/Edge when hardset in the Network Mode, but that is just too slow to feasibly use. Thought it might be a radio problem, but I've tried two AT&T SIMs and Internet 3G/H+ fires right on up with no problems. So good news if you are on AT&T and wan't a MediaPad X1. I got around 4-5 Mbps download..Plenty fast. But I really don't want to switch to AT&T.
Don't think I have any options at this point. I'm trying to communicate with the store in China I purchased it from, but you can imagine how that is going
I love this device. Really! I would definitely keep this as a full-time daily device if I can get this working. The build quality is fantastic (except for this problem of course), screen is great, battery is great, and it's really compact for a 7 inch screen. But.....it doesn't work on the Uncarrier!!
I'll see if the T-Mobile Engineers have any suggestions, and if that doesn't have any positive results, which I'm sure it won't, I will have to try and either get a refund or sell it online! (Any AT&T customers want a good deal on a beautiful 7 inch phablet?)
Sorry for the length of this. Anyone have any experience with this issue, or maybe can anyone out there in Phoenix area validate if their's is working on T-Mobile?
Thanks.
P.S. I have a Huawei Ascend Mate 2....Sweeeeeet device. Love it! But unfortunately it seemed to get smaller the longer I had it. It was time to upgrade to a bigger screen. Anyone else have that problem with your devices shrinking on you, lol?

You on T-Mobile? I received my MediaPad 3 days ago, never been able to get data yet. I'm assuming at this point I never will and am close to moving on. What has your experience been so far overall with the MediaPad?

Yeah I'm on tmobile, but don't have a media pad. I was searching to see if anyone mentioned any data issues on tmobile on xda and found your post. The issue might just be tmobile, not the hardware because I found a lot of people saying the same thing on tmobile' s Facebook page. I also had the icon show up, but no data.

Good to know. I have a ticket in with a T-Mobile Engineer. Should hear back within the next day or so. I will keep you informed of what I am told. My wife has my old Verizon Samsung Note 2 on T-Mobile and it's been working fine. It would also be using the 3G 1900 Mhz frequency. So you would think if the Note 2 Internet is working right now on T-Mobile, my 3G Mediapad X1 should work too. But it doesn't
MediaPad X1 no Internet with T-Mobile wifi hotspot
So on top of not being able to get internet with my T-Mobile SIM insert into my Mediapad, I'm also not able to get Internet when I have my Mate 2 setup as a wifi hotspot and the Mediapad using a wifi connection to the hotspot. Unable to browse to any sites. The Mediapad does get internet while connected via wifi to home router. How strange is that! Again, AT&T SIM works fine.
same problem in Tampa fl

I have metro pcs ( T-Mobile) had good bandwidth 6\8 MBS but won't stay connected metro put in APN settings witch may it very stable but now only get 20 k witch sucks but always have signal if you get APN settings should solve problem ,metro supports x1
I received my new XA Ultra from Amazon yesterday. Popped in my SIM and started setting it up. It had two software updates out of the box, so I applied them, then started installing apps. I noticed that my cell connectivity would completely drop (no bars), then come back. When I checked in the Access Point settings, the option to discover carriers would appear, then disappear.
I assumed it was some kind of software corruption, so I factory reset, but it continued doing it. I also tried pulling the sim out and putting it back in several times. I can only assume that I somehow got a defective unit or that one of the software updates applied the radio incorrectly. I processed a return with Amazon and have a replacement coming later this week.
I hope Amazon doesn't turn around and resell it through warehouse deals. I have received a few devices from them that they clearly didn't test and I was very explicit in my comments for the return. I'm just hoping that my replacement doesn't exhibit the same issues because I'm not sure what else it could be. It's not my SIM. All of my other phones stay connected to AT&T just fine in the same spot.

It's definitely fully compatible. It even downloads the correct APNs, but then they just disappear and the signal drops completely. I get full LTE speeds when it's working and nothing when it's not. I also tested a T-Mobile SIM and, while it holds onto the signal longer, it does the same thing (drops completely).
I plugged the phone into a computer and did a complete software restore, which didn't fix the issue. At this point, I'm sure it's either hardware or a really bad ROM update. I'm hoping it's hardware, because if not, that means that the replacement will have the same issue after applying the software updates to it.
This is my second Sony xa ultra with the same issue here's what happened
Purchases from best buy didn't setup until I got home had 2 update applied them signal drop and reset constantly I figured it was because I have bad reception in my area but the more I looked at the phone I noticed the build quality on the metal bumper wasn't sealed in some areas so I grabbed the packaging and headed back to Best Buy keeping note of the signal issues as I drove there (disconnected from WiFi of course) I noticed the signal did not drop connection at all on the way to Best Buy return the phone and explain to him the issues that I had at home with the signal and also wasn't happy with the build quality defect so I returned it and exchange for another one immediately popped the Sim in it downloaded my APN and I had LTE drove home no drop issues connected to wifi installed the two updates then I drop issue return

The replacement model I received from Amazon did it as well. Right out of the box, before updates, it was dropping the signal. Are you on AT&T?
I watched it really closely. I think I know what's happening. It's not falling back to HSPA. When the LTE is too weak, it simply drops completely until it can reconnect to LTE. If you set it to HSPA only in the mobile networks menu, you will never lose your signal. I tested it with both T-Mobile and AT&T with the same results.
This is a pretty major defect.
You might be on to something, yes I'm also on AT&T.. but I can't find HSPA in mobile network should it be GSM only or LTE (preferred)

It should be something like "GSM/WCDMA Auto" or "WCDMA only". Basically anything without LTE (except CDMA).
I'm honestly just glad to finally have someone else confirm. The chances of having two defective units in a row are extremely slim. Really liked the device otherwise, too, especially for the price.
I tested it for hours. I never got a disconnect on HSPA when I had that set. I just wasn't willing to live with that restriction.
Me as well!! phone is perfect for the price I paid out of pocket I had a BB gift card. I've been shopping for the right phone for a month now I've had about 5 phone from 700 to 200 bucks the expensive ones we're worth the price and the cheaper ones didn't feed my power craving I'm pretty happy with this one for the moment, thanks for the tip
This may be an AT&T SIM related issue.
I have T-Mobile and with my T-Mobile SIM I have no problems. I tried my friend's AT&T SIM, downloaded the APN, rebooted, and sure enough signal drops just like you're experiencing.
I'm having the same exact issue as previous posts with my Ultra. I purchased the unit from best buy the day it came out and using it on AT&T. I love the phone but the issue with completely losing connectivity is a bit annoying. Called customer service and they gave me the same website to fix software issues. Just curious as to why I'll be in same location without movement and then all of a sudden lose my signal.
I have the same problem using cricket wireless which is using att's network, lte signal comes and goes, this is becoming really annoying, is there a fix for this already, or should i return the phone
So I just got off the phone with Sony and they said I would have to send in the phone for repair leaving me with no phone. I've had issues before with phones and the companies just send you a new unit with a box and return label to send back defective unit. The rep said maybe my provider would give me a loaner phone.... Smh Looks like it might be time to leave Sony. Maybe I'll have better luck with the Lenovo Phab Pro 2 coming out next month.
Same issue here, right out of the box today.... Using AT&T reseller and I would have to agree that it is an issue as was mentioned earlier where the phone is somehow not able to fall back on to HSPA on a weak LTE connection so it just completely disconnects. Strange thing is where I am using it (at my desk in my office) I never had an issue of LTE dropping off with other brands of phones. As soon as I left the cell area and started using it at home or at another location further away I had no dropped LTE signals. I think Sony support will be useless unless we can somehow get past the standard support desk. They told me they have no higher support I can be directed to, that I would either just do a software repair (which I assumed correctly would not work) or send it in to service. Not sure what I am going to do at this point, cannot have my phone jumping out of service every 2 minutes during the work day. Any other suggestions would be appreciated.
EDIT: upon further review (using LTE discovery App) it appears that "some" At&t sites are having issues staying connected with LTE band 17 on this phone. I drove up to one of the sites the phone has issues with. It had a solid,strong signal within 1 block of the tower and band 17 still disconnected the radio completely. As soon as it reset and moved to band 4 it stayed on without disconnecting until I moved away from the site far enough for band 17 to kick back in. At that point it continued to disconnect every 1 -2 minutes until I moved the phone mode into HSPA preferred. I don't know what to say about this, band 17 works great on 2 towers within 10 miles of here, but some others and this tower causes the phone to go into a fit. Clearly the phone has LTE issues as any other ATT LTE phone on band 17 I have used in this area has always worked just fine. Anybody have an opinion on this???
I have what I think is the issue, now if we have any way to get this information to anyone who can actually do something about it. I have 2 sites by my home that the phone works flawlessly on LTE... no dropped LTE signal whatsoever. Here is the difference... they are band 17 ONLY sites where the sites my phone is unable to hold a LTE signal when the At&T site is broadcasting both band 4 and 17. That would explain why the rest of the sites around where I work do not maintain a signal either. We need to all contact Sony support and somehow get this information thru to them. The issue is the phone clearly being unable to handle a site broadcasting 4 and 17 which I think is a majority of them.

It's still not falling back in HSPA like it should. If it has difficulty with an LTE connection, it should not drop connectivity completely.

Agreed, but keep in mind that my XE ultra was 1 block from the tower with incredible LTE signal strength and it still completely shut the radio down and restarted. This is not for lack of signal but a complete inability for it to handle a band 17,4 tower. Although it would be great if it just moved into HSPA, that would mean your phone would be in HSPA 80% of the time, even when the LTE signal was completely adequate for the area. This clearly is a defect that makes the phone basically unusable (as it continually shuts the radio on and off) until Sony can figure this out. My concern... there is no way to talk to anyone at Sony that can do anything about this until they get enough support complaints directly related to this issue, this could take months not including the time they need to program an update and fix. Very frustrating.

Frustrated with this as well, hopefully sony fixes this problem more sooner than later
Received an update yesterday and I can't confirm 100% but it appears I haven't had as bad connection (popping in and out). I'm in Houston btw.
I got the update and so far phone has been working fine
The latest updates from sony fixed this issue.. so happy and enjoying it now
Hi
I wanted to buy this from gearbest.
Will it work on AT&T with all the LTE bands?

I'd like to say "yes", but have found out the hard way that it depends on exactly which part of AT&T's network you intend to use it on.
I created a thread which I haven't yet updated, which outlines some issues I had. Turns out that my X820 as well as a different LeEco X82X (can't remember - same model ) do NOT work with AT&T in my area at all, and I live very close to the antennae. However, when I travel out of town, the phones work great. AT&T can't seem to figure out why this part of their network is different, but something certainly is. YMMV.
At the moment, there doesn't seem to be a large enough sample size in the US to compare notes and find possible network issues with this phone.
I have it, and it works for me in North Florida in AT&T

I have more info on my issue with this phone on AT&T, and it's an odd one. LTE works great, but if I am directly under the antennae, or within line of site of them, 3G shows full bars, but it does not work and I cannot place or receive a call. If I walk a block away, and have a building between the phone and the antennae, 3G works perfectly. If I initiate a call where it works, I can move back to LOS, and call does not drop. No other phone seems to have this issue, so there is something very different in the 3G implementation in these phones which is responsible for this.
I wish someone out there had an idea as to what is causing this. One of AT&T's network engineers, who witnessed this first-hand, is stumped and I'm short on ideas to remedy it.

I got an x829 yesterday (live in the US) and plan on using it with Straight Talk/AT&T (getting the nano sim now). Have you flashed yours to a newer/custom ROM and it still works with AT&T? If so which ROM?

I have two of these phones, and both have the issue I described above. If I were to guess, it probably has something to do with initial 3G handshake timing.
One of the phones is running Madsurfer's 21s. It may have been a dirty flash over stock China ROM, but I seem to recall that one being a clean flash (wife's phone, so I don't mess with it much.) The other is Small EUI by aurel V7, dirty flashed over Rom V6-X820 of Bshuy2003.
I have observed no real differences with regard to the 3G connectivity issue between either phone, with any firmware. I'm thinking it is something at a lower level which is causing this odd issue.
I haven't received my max2 yet but I have read through allot of these posts and I remember reading about using the #*#* code to force LTE and it helped mobile connections. Also I saw that 19s CN or 17s India eui has VoLTE support. Lastly I noticed that the posted 23s beta cooked eui that Steve Mars posted has new modem files. You may try that as well. Hope that helps!

Thanks for the info, but I think the issue runs pretty deep inside these phones. If I knew more about the hierarchy of the software/firmware, where network negotiations are concerned, I'd have a better idea where to look for a solution. But I can say that I have tried virtually every ROM and modem file available, and this odd behavior persists. It's possible that it's specific to my home site, but according to the engineer, AT&T's sites are pretty standardized. The fact that other phones don't exhibit it, tends to point to something deep inside the Max2 as being the culprit. It's an insidious problem, as one might not realize that there was an issue, unless one happens to be close to a tower, trying to unsuccessfully make or receive a call, with full bars showing.
IIRC, the iPhone also had some strange issues on the AT&T network in the early days, and it took some concerted effort between AT&T and Apple to get it sorted out. The chances of of something like that happening to solve issues with these phones is probably next to nil.
Randy do you have LTE on your account? Could it be the eNode trying to promote you onto a better link and the baseband failing that negotiation?

I do have LTE on my account. The phone is connected, by default, to LTE, and falls back to WCDMA when making a call as it should. I have monitored signal strengths throughout the process, and they are very high, due to to my proximity to the tower. Locking the phone to WCDMA makes no difference.
When the phone doesn't have line-of-sight to the tower, and/or that LOS is significantly obscured, the UMTS signal goes below -60dba and the phone works perfectly. Thinking the signal strength was the key, the output of the tower was artificially reduced to below that level, as a troubleshooting test. It still did not allow the phones to work on WCDMA to make calls, even though it still showed a 3G connection with full bars. I'm not a telcom engineer, but it really seems like a timing problem, where the reflected signals work, but signals received directly from the transmitter do not. Again, the problem exists only at the point where the 3G link is initiated, either by the handset or the tower. Once a call is established, that session works fine, no matter the proximity to the tower thereafter. But once moved into the areas of LOS to the tower with an active call session and I end the call, the phone can no longer make or receive calls in those areas.
Short answer: sorta

Alright so I have been using this phone for about 6 months and it kinda sorta does. I am using the x820 one btw. I get about 80% up time with this phone. I can't really make or receive calls without the phone dropping them within the 1st minute. Let me explain further. So firstly, when I am on LTE (if not on 4G (I'll explain later)), and try and make a call, I will usually get switched over to 4G and then as the call is attempting it will completely lose service and say I can't complete the call. Then after that attempt, I will usually get my service back. And it will keep doing that unless I get lucky then if I actually can make a call then I will be lucky if I get a full minute or 2 before the call drops because of loss of service. Now for the later explanation. So basically I have noticed just because I am supposed to get LTE doesn't mean you will get the service. Also you will drop service a bunch and it gets very aggravating! I have verified my results in FL, GA, and TN.
Hey guys,
my Mate 20 Pro won't connect to 5ghz wifi.
I always need to adjust settings in the menu of the router which is inconvenient.
I of course can't do that at every place that I go to.
Especially since many people don't even know how to get there and their log in data.
Is there a fix for that?
Does even anyone else have that?
I have connected my M20Pro to 2 different 5 Ghz wireless access points without issues, both using WPA2 security,
I am having a slightly different problem. My phone will connect to the 5ghz network, but once I am more than 10 feet away the speed drops to almost nothing. The 2.4ghz network off the same router is unaffected. I have tried factory resetting my phone and resetting the router and nothing has resolved the issue.
You can make sure that the WiFi of 5G is hidden， Make sure WiFi is household or public？
I use 5ghz wifi at 3 different locations, no issues. 2.4ghz always has a greater range though. Any issues are with the routers.
Sorry for the late update.
I've got my device replaced because of the green lights at the edge and around the notch.
WiFi works perfectly now.
I get up to 100% of our bandwidth which I haven't seen in any other mobile device.
For me, asking Vodafone to exchange the device was the easiest and quickest way.
I've exchanged the device right in the store and was ready to go.
As I've heard (but didn't need), Huawei offers a similar replacement service.
I was told that I would be contacted later by the Huawei online chat but wasn't since Vodafone was quicker.
This was in Germany. Might be different in other cases and especially countries.

Like I've said, I've got a replacement device because of the green screen issue.
The new device has the best wifi connection I've ever seen.
Don't know if it was the old device or a software issue though.
