RIght, firstly I've got a UK Z2 (Vodafone model, but unlocked and subsequently flashed with a different ROM).
My problem is that I can't connect to a router that only operates on the following channels at 5GHz; 149. 153, 157, 161.
These are apparently valid in the UK, although my iMac won't see them - but it's a 2009 model. My MacBook Air (US import) does, and my Z1 Compact (with EU Generic ROM) does. So does my Xperia SP. The Z1 I recently sold did too.
Now I assumed that the UK ROM, and now my Taiwanese Z2 ROM (the router is Taiwanese too), supported it because when I turn on the phone, it can see the router. However, it can't connect. It never gets an IP address, and then soon after it disappears never to be seen again! That's unless I reboot, but even then - sometimes - it won't show then either.
The Wi-Fi signal is excellent.
I've read before (for the Xperia Z) that you need a SIM card inserted, and there is. It's a Three UK SIM. That perhaps tells the phone what channels to use? But if it thinks these channels are not allowed, why does it initially show the router? Is there a delay before it notices what can't be used? And why would one UK SIM hide the channels, but not another?
In any case, my Z1 Compact currently has no SIM card inserted but still works.
I'm very confused. It doesn't appear to be a hardware issue (it would be a weird problem if it was), so it must be down to the ROM - and I've had both .55 (Vodafone original and then a EU generic) and now the Taiwanese .69 ROM.
Sorry for the long post, but I wanted to try and pre-empt any questions that might get asked.
Basically, is anyone else having the same issue and does anyone know a potential solution? I can't change the channels on the router and there's no other firmware for it. Obviously I could change the router, but I think I'll just have to stick with 2.4GHz in that case.
I know you say no fw is available for the router but im assuming you mean stock? Is dd-wrt/tomato available for it?
My s3 was the same on every custom rom i tried, 5ghz was always iffy :/ Will let you know if 5Ghz works for me when my z2 arrives friday
5 ghz works for me but not using the mentioned channels, in fact my router Won't even allow me to use those channels.

The thing is, the router is from Taiwan and there doesn't appear to be any way to change the channels it operates on. For 5GHz, those four channels are it.
They do appear to be legal in the UK, but many devices won't support them.
I am just confused as to why the channels work on the SP, Z and Z1 Compact but not the Z2. And even more confused because it will show up for a little while but not connect, then disappear. That's an odd way of restricting Wi-Fi channels on the part of the handset.
Can you maybe doing a forget network and then re-adding it?
I'm in Singapore and have no problem connecting to 5Ghz channel 161.
I don't think it makes much sense for them to limit channels on the client side as people can travel anywhere with their smartphones and should be able to use any channel available..

Yes, but some devices do still restrict channels - based on what region you've set, and possibly in this case the SIM card.
I'll need to do further tests, like swapping the SIM for one, to see if that makes it work. At least then I might be in a position to report it as a bug to Sony.
I have removed/forgotten it when it was there, forcing me to re-enter the code, and it just doesn't connect. And while it isn't connected, it does then stop the phone connecting to anything else unless manually select it.
whats the make/model of the router?
Can confirm 5Ghz works just fine for me using Doom's kernel and Aur

I previously owned a Z1 and found that 5ghz wifi was very poor on this device.....I now have a Z2 and the wifi is exactly the same.......works well on 2.4ghz, but poor on 5ghz. My wife's Nexus 5 works well on 5 Ghz so it must be down to Sony's implementation. I am using channels 36-48 not sure if I can access the higher channels, I presume not....think my router only has the lower channels......I have searched the web before for an answer to the problem, but no luck as yet....:crying:
just to add my 2cents to this, My UK bt homehub doesn't have those higher 5Ghz channels highest is 128 lowest is 36
Yeah, this has happened to me recently aswell. I used to connect the 5GHz 802.11ac wi-fi network at home on my Sony Xperia Z2, but a couple'o days ago it disappared. I can't see the 5GHz signal, I'm using 2.4GHz instead. But my laptop can see 5GHz signal and connect without any problems. The channels on 5GHz signal is 149,153 by the way. And channels 11, 7 on 2.4GHz signal.
So what might be the problem within my Sony Xperia Z2?
Thanks in advance.
Oh I just relieved that this problem is not only for me... Okay as some people mentioned wifi for Z1 was poor and Z too... so it might be problem w/
design of Z series. I am using AC-7260 wlan for my PC and seeing 5Ghz AP. But not for Z2....
No jamming around my home, no one is using 5GHz other than my AP.
My Z2 works excellent on my 5ghz channel. I'm on vacation now so can't verify the channel I used. What I do know, is certain devices don't work as advertised with 5ghz. Just because one device sees it doesn't mean every device will. I've had to switch channels a few times for different phones although my laptop has always seen it.
Yeah, it must be the channel issue, I suppose. But at first, my Xperia Z2 was connecting to 5GHz signal without a problem... After a while this issue started. I didn't change any channels or something on my router, either. Interesting...
5GHz signals have inherently smaller ranges than 2.4GHz ones.
That said, my Z2 connects to my 5Ghz AC network just fine (range sucks though) but it has a problem keeping the connection to the 2.4GHz N/Mixed network from the same router (dualband ASUS RT-AC66U) alive after a period of time. It will still show as connected (with good signal strength) but will not have any access to anything else.

Yeah, I'm well aware of this range thing between two signals. But my problem isn't something about it. My phone used to see and connect 5 GHz signal, but it doesn't see 5 GHz signal at all now. Even when I put my phone right on the router, between 6 antennae. (3 x 2.4GHz, 3 x 5GHz antenna)
This must either a software issue, or channels on 5GHz signal... But no, my phone was connecting without any problems for 3 weeks with the same channels. Must be software.
This isn't my only problem with wifi anyway, there's also a Bluetooth interference with 2.4GHz signal. Happens when Bluetooth is on at the same time with wifi. And when connected 2.4GHz signal, connection drops sometimes.
i found this thread now i had posted one earlier today.
what I have figured out is - the moment the SIM is inserted Z2 is taking off the channels that are not "legal" possible in the country determined by SIM.
I am on Telkomsel - indonesia, if NO SIM - I am able to connect on 5 GHZ very well. but once it senses the SIM card, the 5 GHZ vanishes.
This never happend on Z Ultra!
next step is to test on other channels on the router in 5 GHZ to see if it is limitation of Z2. Right now my router supports only 4 channels - 36 40 44 48 on 5 ghz band.
otherwise my mac and other units connect and work pretty well on these channels!
Alright, I've had my Xperia Z2 for 3 months now. I've never connected to my 5 GHz 802.11ac signal before, the phone doesn't detect it. I can only connect via 2.4 GHz band.
Why my phone doesn't detect 5 GHz wifi signal? What's wrong? What do you suggest?
What ia the max link speed you get on 5ghz in z1 compact
I don't know if anyone with a Z2 still has this problem, but I did and I seem to have fixed it by not setting my router to VHT80, but to HT40 instead. As a side note, my Chromecast seems to be able to connect to it now, too. My router is a Netgear Nighthawk (R7000) running the latest DD-WRT Kong Mod.
I live in Germany, but travel and work in the USA quite often. I have a US spec T-Mobile Note 4 and I'm thinking of grabbing the Gear S.
My Note 4 handles the networks in the USA and here well (vodafone), so I wouldn't be using the Gear S as much for data, but I don't want to be stuck if I need to use it and I don't have my phone. I will use it for day to day use and while traveling, as well as for music and fitness tracking while running. With all of that said, would I get enough functionality out of the watch if I purchased a US spec? Does the aGPS need a data connection, or will it be fine functioning as a distance tracker/mp3 player/heart-rate monitor without a 3G connection?
I guess that's the gist of the question. Calling and texting should work regardless, but will the aGPS work without data in Europe? Should I just get an EU model? I should eventually (2 years?) move back to the USA or to Asia, but by then I fully expect to move on to the next smartwatch.
I live in the UK and travel to the US. My watch was imported from Russia and I re flashed it with UK firmware.!
I suggest you purchase your Gear S in the EU. The mobile set up here is better for SIM use only purposes, and then use a US sim in it when you're back home. The Gear S is not locked to any network so should take any SIM.
Or simply use Bluetooth and run the GearS via the Note for notifications and calls, plus the health app etc. That's how I run it here.
Thanks for the suggestion. I think you're right. I'm going to see how my Note 4 performs for the next couple of weeks and then pull the trigger unless something new is announced imminent. I've got an OLD Motoactiv currently filling the role of smartwatch and it's great for fitness, but huge and the battery life and functionality are limited.
Gear S is dual band device. Regardless where you purchased, it won't work on both EU and US because the bands don't match. You will need a quad-band device to work. So forget about it being working any way other than tether to your phone via BT.

I already know it's dual band. I already know it won't work in both.
I was asking if at least the aGPS would work in both since I would have my Galaxy Note 4 which works in both for most use cases besides my fitness use which would need the aGPS.
Depends on which app you use. Without the network connection, S Health and Here maps are hopeless (takes very long time and Here map typically will give up before that). Nike+ will work as it does not try to resolve location on the watch.
Of course, if you have the phone with you, it doesn't matter. The watch will use phone's GPS all the time if it is available.

Ok. What WILL use the aGPS without a data connection to track running? If there is something, I think I'll get a US spec for use in the EU since I'll have my phone in every other instance besides running with the watch.
If there isn't a way to use the aGPS without the data connection, I'll have to get the EU spec and just use my Motoactv on the rare occasions I want to track my running in the US while I'm on a trip.
Common mis-conception about aGPS. It is no difference than other GPS. The 'a' part means it can speed up the initial acquisition if there is a network connection to off load the calculation elsewhere. It still fully capable of receiving its own GPS signal. It doesn't mean the GPS won't work without the network connection. All modern cell phone GPS is like this.
Without a network connection, the initial acquisition takes a real long time (5 to 10 minutes depending on many variables) on the Gear S. With the network connection, it is about 20 seconds. Nike+ opt to record raw satellite data and let the server to do the calculation of exact location. It is extremely fast for Nike+ app to get lock and start recording (about 5 seconds or less).
Hello everyone.
As a proud owner of Xiaomi Redmi Note 3 Pro, I have a problem that lasts for month now.
I actually have a Mi Band that is always connected via bluetooth on my phone, and i need bluetooth to be always on. The problem is that when i am on the 2.4 ghz band on my wifi, sometimes the internet speed drops to 1 mbp or less, as well as an high ping and totally unstable connexion.
The fact is the problem is totally random and not related to a specific use of the bluetooth (except for controllers apparently ). In fact, where i use a bluetooth speaker as well, i do not have any problem. The problem is not specific to my phone, as i had the same problem with my previous phone ( a OnePlus X ) and with my Onda Tablet as well ( Wifi is unusable when i connect for example a bluetooth controller ).
The problem totally disappears when i use the 5 ghz band or when i desactivate the bluetooth (but for a reason, the 2.4 ghz band seems more "sensible" of interferences ). For notice, my rooter is a dual band (2,4 Ghz and 5 ghz).
I have tried to change the wifi channel on my router, it's the same problem as well. The problem lasts for months now and really consumed my patience, as he appears totally randomly and with no reason at all ( except for controllers ). I have searched for answers but cannot find any satisfactory response, only some clues related more or less with my problem. I can live somewell with the problem but actually i need solutions or at least clues of the origin of the problem
Phone : Xiaomi Redmi Note 3 Pro (Special "Global" Edition)
Rooter : Orange Livebox Play (France ISP)
Thank you in advance for your help
Edit : I Know that Bluetooth use the same frequency as the wifi, but normally the bluetooth has been made to "prevent" such interferences. The fact is that in my case these interferences occur without any clue of their origin
+1 ... have you found a fix?
I also have the problems with wifi and bluetooth, but on the bluetooth mouse instead of mi band. As soon as I start downloading something, mouse cursor starts to lag. As I have researched the problem, the only real solution was to change wifi to 5ghz like you mentioned. Unfortunately, my router doesn't have 5ghz band, so the workaround I found was to change the Channel selection on the router from Auto to some other channel. The problem didn't disappear, but it's not lagging as much anymore.
Also, why don't leave router on 5ghz?
Hey all
I got my honor 8x a few days ago, everything is perfect except one thing : the wifi on it is quite weak compared to my old phone (xiaomi redmi 6a which is a weak phone)
Anyone experiencing similar issues?
Thanks in advance

I couldn't agree more with you that a modern phone such as the 8x would omit 5ghz wifi in this age and time. Even my Samsung Galaxy from 5 years ago have them. I also bought the Honor 8x model JSN-22 which do not support 5ghz wifi either. This is the biggest disappointment I have with the otherwise excellent phone. I also search around for solution and found out that there are three variant of the 8x and only the model JSN-21 support dual band wifi ,the rest(like ours) don't. As far as I know JSN 21 are available in some European countries only, and unfortunately my friend, we got the short end of the stick!

And JSN-23 also lacks NFC! I don't understand why they did this. Every other version of the Honor 8x seems to support it. It's so confusing that sellers were advertising the 23 as having 5ghz and NFC because the other versions had it. When going back to the sellers and letting them know - they are telling me I am wrong. Clearly there are some pretty big differences between the versions available.
All I can say is be very careful about which model you buy as retailers seem to be struggling with getting this stuff right (even online review sites).
5ghz not supported
So i'm confused, all specs show it will do 5ghz AC but the phones wont. Is this simply a disabled feature that the newest update will unlock or a Rom will allow or are we up a river without a paddle?
Been noticing that my signal drops more than normal at home and at work since swithching to the xperia, Used to have both a Note10+5g which would get consitant 5g at full signal, and the same for my Oneplus 9Pro, But with the xperia ill get 1-2bars 5g in the same room if it hasnt dropped to 4G at 2 bar or 3G.

Just switched from OP10 Pro to Sony and I noticed this same thing. With my OP10 Pro I usually got very good signal, but with Xperia the signal is very poor.
Me as well, especially on WiFi. My router supports only WiFi 4 and I get poor signal if not directly next to the router.

I switched from Nothing Phone 1 to Sony and I noticed this same thing. With my NP1 I usually had a very excellent signal,
Okay glad it's not just me, but I wonder why it's like that now
Phew, I am not alone. Mine works poorly with Wifi 6. Any ideas to fix?
I've noticed this also, and the Bluetooth connection (with Sony's WH-1000XM4 and WF-1000XM3) is also very weak.

I'm also switching from xperia 1 to 1 IV and bought a metal frame case for the phone with a lower signal, the signal has dropped even more I don't use a case anymore
Unfortunately, the GPS signal is weak a lot of times and stops navigating.

Will this signal issue be fixed with an upgrade?
I do hope that Sony will fix these soon.
Signals should not be an issue in 2022. However, be aware that the GPS is only a single-band one, despite some specs around the net.

Hi, I just realized the solution.
Please install voWIFI app via play store, disable DSDS, and you are done!
If you totally missed your Antenna, be sure that u are using the first sim slot for your sim card

Same here. It looks so nice with metal case. Call quality not that great also
Metal cases do degrade network signal very much. be it of any kind, GPS, carrier signals, Bluetooth and WI FI.
Sony uses its signal scale in quality, the rest of the companies in power.
I didn't get a 1 IV until the Android 13 release, upgrading from a 5 III. I also use a work iPhone 11 regularly. I'm in the US and my phones are all US market models, and I live in a large metropolitan area. Both of my phones are in carbon fiber cases with metal in them. Here are my observations, which seem to be more positive than what is posted here.
Wifi: My home network is Wifi 6, and the signal on the 1 IV is usually weaker than the iPhone 11. But, it's only by 1 or 2 dbm, per the data from my router. However, if you run a speedtest on both phones, the Xperia 1IV always gives a higher Mbps reading than the iPhone.
BT: I have WF-1000XM3 and M4s and both work fine on both phones. I can get further away from the phone with either headphones from the iPhone than the Xperia, but the Xperia works fine if it's sitting next to me or in my pocket. No issues with connecting to other devices like speakers or car stereos.
Cellular: My 1 IV is on T-Mobile, while my iPhone is on Verizon, so hard to compare there. However, my wife has an iPhone 14 Pro Max on T-Mobile, and in spot comparisons, my Xperia gets better reception and faster data connectivity. When I'm on 5G, my Xperia regularly gets over 1Gbps download speeds, even without full bars on the signal meter.
I am from Croatia and I have very poor 3G signal, 2G, 4G and 5G signals are OK so in my home there is no 3G signal at all and I am not available because my network doesnt have VoLTE. I am on 64.1.A.0.882 firmware. Before I would have signal problems but restart would fix that. Now, after restart nothing is fixed. Till now I reset my phone 2 times and it was on service repair because of fingerprint sensor. 2 days ago everything was OK. I don't know what is going on. Is there any fix? Could this be Google Play System problem? Because yesterday I got another Google Play System update of 9 MB for March and around that time this problem started and I don't see any fix.
I manage to solve problem. I call this code in the phone *#*#4636#*#* and it opens Testing. In there I went to
Phone info --> three dots --> Select radio band --> Automatic
and after that everything start to work. I don't know what radio band was set before because I couldn't read that. I gess that every time when problem happens I'll have to do this.
