S9+ showing "connected to WLAN, no internet" - Samsung Galaxy S9+ Questions & Answers

So, I got my S9+ (international version, DUOS, 256 GB) last week from the Samsung store. I am on stock ROM (and will stay as long as my warranty lasts or someone finds a way to root with Knox 0x0, which I am not expecting).
At home, I have a WLAN Mesh (AVM Fritz!Box 6590 Cable, 2x AVM Fritz! 1750E Repeater on a wired connection), everything working great with any device.
Except my S9+. It connects and everything is fine, at some point - especially when using it for e.g. streaming Netflix or so - it will stay connected to the WLAN but will say "no internet access". Switching WLAN on and off fixes the issue until it happens the next time (minutes to hours later). I have no special settings, no neighbouring networks which would interfere. I have 2,4 and 5 GHz active and automatic channel selection. All other devices in my home work with no problems. I have found similar issues froim users on other Samsung phones (S6/7/8 series (my former S5 on Resurrection Remix Oreo does not show t his behaviour)), but no answers that worked (like forget the network, reboot and reenter credentials).
Quite annoying, anyone knows a fix? Big THANKS in advance.

No one experiencing the same thing or havin any ideas?

I have had the same issue in the beginning with the phone. I have a router with a cisco switch connected to it. The standard router's wifi wasn't sufficient in coverage through my house. I got hold of a cisco AP and connected it to the switch and disabled the wifi on the router. That's when my issue started. Fiddled around trying various options, but the one that worked for me was to tell the phone to forget my network, restart the phone and then "setup" the wifi on the phone again(password for wifi needed to be entered as it sees the network as a new one) Haven't had the issue after that. I did notice at my office that even though the wifi conection is good, that if it goes below a certain percentage, the mobile data will kick in, although I have that option switched off. I also picked up that if your line connection's speed goes very low for whatever reason, the same problem appears again that the phone assumes there is no internet

Thanks, this is what I've read from other threads (with S7, S8), too. But this didn't work for me. My repeaters get ther signal through LAN cable and I have a fast connection, coverage all over my house and garden. I really do not have an idea on what to try...

[Q] Optimus one Wifi issues - please advise

Hi guys, so here's the deal : Just got a brand new Optimus One and the Wifi dosen't really work. It took me ages to get it to detect my home network ( Realtek RTL8187, used as a hotspot via win7's wireless miniport adapter - so basically virtual hotspot) Once I managed to get a connection the device would either be stuck at "obtaining ip adress from..." or would simply disconnect and reconnect in a quick burst. I finally managed to get it to connect by manually assigning the internet sharing permissions for the virtual miniport, but the speed is abysmal! We're talking to the order of bytes/s, measured both by attempting a small download from the phone and by reading the in/out data on the pc connection info. Upon some further poking around, a few wifi adapter and phone restarts later, I notice that when I connect to my hotspot the phone's wifi manager reports a normal speed of 54mb/s, but when I actually try to use the connection (say, the youtube app) it works fine for a second or two (it usually loads a bit of a vid, or half of a big webpage) and then drops down to the aforementioned speed and the phone's wifi manager indicated that the connection is 2mb/s
Also, I went out before setting up my home network to a mall and tried to connect to one of the free hotspots available. On some, it would connect straight away, but be very slow (signal wasn't great) and on one (max signal) it would disconnect/reconnect in very short bursts (10-15 times a minute) and it would eventually establish the connection. Then the same speed issue as above: works fine for a few seconds, drops down to unusable. Didn't think about checking the connection speed there, simply thought the public network was overused. In hindsight, the problems were similar to the ones experienced at home
A few side notes: The 3g speed is fine, consistent and problem-free
I have tried changing my home wifi's frequency to a number of settings (there are quite a few other wifi's around, I know it could cause issues if they overlap)
My wifi connection was actually not detected by a friend's laptop wifi, but we could connect our computers just fine via ad-hoc (which from what I've heard is a no-go with android at the moment - and the phone does not see ad-hoc)
The phone is brand new, only installed a handfull of apps on it, didn't change any relevant settings (I think)
Set wifi sleep policy to "never"
My pc wireless adapter worked just fine in the past, used it for a few months as the main internet connection, and even with half-signal it would achieve good speed. I also moved the antenna away from the PC itself to avoid interference
I set my PC to use only 802.11b since I've read around that some phones prefer this to 802.11b/g
That's about all I can think of right now. (oh, and It's my first android, so I don't know my way around the OS that great yet)
I appreciate any advice you can give me. Basically I'm trying to find out if it's an issue with my Wifi adapter, it's settings, the phone's settings, or if the phone itself might be broken, so I can send it back to warranty.
Thanks in advance.
Try switching from b to g.
it was initially on b/g

Z2 wifi slow

Having problems with Wifi streaming and YouTube very slow, stop and start every few seconds, got to be the phone as all my other devices stream fine. I have unchecked avoid poor connections in wifi advanced.
Any one else having this problem, will try factory reset.
UK sim free 14w18, firmware 55

I've seen factory resets cure a few problems on here so try that 1st but isn't there a .69 firmware available now as well, maybe try that to?

Good old factory reset and it's working fine.....hasn't. Worked
EDIT.......wifi speeds are slow again, can't watch YouTube or stream films, it's only on this device, ipad 2, galaxy s3 and s2 all stream with no problems.
Can't download the 6 free promo films either as download fails after a short while.

My facebook app is not working great in my phone. Youtube has been fine so far but I find my internet quite slow at home as I have rubbish internet speed. Also in peak times I get very slow internet connection.
Wifi speed still slow, only on this device,
Also is the . 69 firmware carrier specific?
No firmware update prompt on my phone.
no option for 5GHz in wifi advanced menu
Sent from my D6503
A couple of things to try:
* test with other access points
* restarting the router
* disconnecting other devices
* forgetting the network on the z2 and readding it
I actually got great wifi speeds with my z2. It was even able to max out a 100 Mbps cable broadband connection on an AC router. Worked fine in n-mode also.

Have you tested on any other networks?
Take a trip to Starbucks! See if you get any better speeds there (and a nice latte, damn I'd kill for one right now).
glas to see im not the only one. Google Play Store @ 0.02mb/s
What kind of router do you have and how far is it? I'm able to maintain 2-3MB/s (16-24Mbit/s) over a distance of 20 feet with walls and everything in between.
After getting my phone last Tuesday ive noticed this little bug as well, sometimes downloading/updating google play apps it'll be like 0.5MB/sec but usually when I use drop down menu and quick settings and turn off wifi(give it about 10/20secs) then reactivate it im back to around 8-14Mb/sec, some apps dont even show a download progress its that fast lol.
I believe it might be a 5Ghz wifi problem as my BT hub shows my phone connecting to 5GHz channel with no way to stop it apart from turning 5Ghz off at the router :/
So hopefully sony will either fix bug or give us more wifi options like already mentioned so we can make phone connect to what we want.
K stand corrected phone can/does switch between 2.4Ghz/5Ghz, router shows phone connected at 2.4Ghz now. Just updated an app while connected on 2.4Ghz and no problem.
Z2 D6503 Wifi dropping issues
I seem to be getting the same sort of wifi issues as previously stated. I cannot hold a wifi connection on the 2.4ghz band fro more than 20s before its dissociated (ie i still have full connection to the router (3 bars) but cannot get through to the internet). This happens no matter what router i am connected to, whether its at home or at work.
I have tried:
Setting the Wifi optimization checkbox off. No difference
Avoid poor connections is off. No difference.
Stamina mode is off. No difference.
Keep Wifi on during sleep is set to Always. No difference.
Sleep timeout to 30mins. No difference.
I have factory reset the phone. No difference.
I have also check to see if it is my router at home. I have switched between every channel available which made no difference. Security is Wpa/Wpa2 PSK AES which makes no difference. I only have the 2.4ghz available on that router at home (same at work).
My Note 3 and HTC One connect to both routers with no problems at all and do not drop out. Same goes with Sony Vaio Laptop.
I have installed Wifi Fixer on my Z2 to see if it can alleviate the problem and it does somewhat. instead of manually having to turn on and off the wifi toggle to reestablish a connection, the Wifi Fixer does it for me.Approx. every 20-30s in its log it will show the phone "dissociating" from the router, and the the app tries to "reassociate" the connection.
I can connect through wifi transfer to my Note 3 without issue, and the same goes for my TV, so it cant be a hardware fault, as the connection is still excellent strength for both (as well as the router, tested with Wifi Analyzer). This is a very frustrating problem as it makes watching youtube movies impossible, and hotspotting, skype calls, etc.....
And dont even get me started on the bluetooth dropouts. I am disconnected from a bluetooth connection every 66-70s without fail no matter what i try. No issues with my Note 3 and HTC One in the exact same conditions. It will disconnect then reconnect straight away with a delay of about 3 seconds, which makes calls and listening to music a VERY unpleasant experience.
Any ideas on how to fix this? I love everything else on this phone but this wifi/bluetooth connection issue is making it unusable.
connecting to my bt home hub 4 via 5GHz band only has solved my wifi drop out problems.

For me slow Wifi resulted in many issues, You-tube video cannot be played, video streaming from a network storage cannot be done, Facebook videos will stop at the middle etc where the most evident issues. I tried everything possible to resolve this issues and searching the internet also didn't help. Finally decided to fresh install, used PC companion and re-installed the complete software, then restored all apps using google backup service. After this there is no issue till now. The software version is the same I had before reinstall. But now the Video streaming and apps using internet become very responsive.
thanks

[Q] i9300 wifi signal/connection issues - Murata vs Samsung module

Hello team,
My Samsung Galaxy S3 GT-I9300 (international version) started to have wifi problems after stock update to 4.1.2. After that, I´ve tried many software and hardware fixes, including changing the wifi antenna cable. The result was the same, so I decided to try custom ROMs and came straight to CM11.
The wifi signal is very weak, and I can only connect from a few meters from the router
Installed CM11, full wipe cache/data/dalvik and still the same problem, weak wifi, connection only from if close to the wireless router.
Reading all the forums on XDA and CyanogenMod, I found the wifi-fix patch, which writes "murata" on the /data/.cid.info. This fix brought me powerful wireless signal, and now I get full signal bar to my router and even see many neighbor APs... but I am not able to connect. When I try to connect, type de password and than it just goes back to "Saved, protected by WPA/WPA2". I´ve also disabled authentication on the wireless router, and the result is the same. It won't connect not even to open networks, although I see strong signal.
Deleted the wifi_fix patch (delete ¨91fixwifi¨ on init.d, delete ¨.cid.info¨ under /data and rebooting), and went back to old status: very weak wifi signal, but able to connect (associate) if I´m very close to the router.
Turned wifi on and off, airplane on and off, captured log on "Murata" and "Samsung" modes...
Strange is that my wlan mac address is 88:32:9b:xx:xx:xx, which seems to be Samsung, but the Murata brings me powerful signal (although I cannot connect).
Well, I´ve tried many solutions so far, but that´s how far I could go...
Can anyone provide me some clue to solve it? I would be very thankful to have wifi back to my phone.
Log files are in attachment
Murata log (strong wifi, not able to connect)
Samsung log (weak wifi, able to connect when very close to wireless router)
Thank you all!
I too have only a range of 3 metres, I have 7 routers in the house because of this, yet I have less than 15% coverage of the house with this device. To put that in perspective, an HTC One X and Atrix 2 has 90% coverage with 2 routers. I'm 1 metre from the router in my room and I've got 1 bar, sometimes 2 briefly.
[Edit]
Woah, I tried the fix from:
http://forum.xda-developers.com/galaxy-s3/help/cm9-i9300-advice-t1898004/post41394293
Seeing as it can easily be reverted, it displays very high signal. What I'd expect. But it doesn't let me connect either. I also tried CM10.1 like the people who it worked for, it didn't work.

Fixes for slow and dropping wifi

(April 24th, 2015) After searching for a solution to my wifi dropping I collected a comprehensive list that has helped in one way or another. After seeing similar issues on S5 phones it appears this isn't solely a S6 problem. If you find or have used a method not on the list please report and I'll add it.
Possible fixes for Galaxy S6 WiFi problems:
Factory Reset
“Forgetting” your Wifi Network and Reconnecting
Settings ->Wi-Fi. Hit menu then Advanced. Make sure Keep Wi-Fi on is set to Always.
Settings, more networks, mobile network, uncheck Connection Optimizer
Under the Wi-Fi settings uncheck "Smart Network Switch"
Resetting the Modem/Router
Settings→wifi→WPS Button and same button on modem/router to 'lock on'
Switching from DHCP to Static Connection on Phone
Connect to your router's 2.4GHz band instead of 5GHz
Install a DNS changer app, select primary/secondary servers to Google or yandex.
Changing the Router Bandwidth Settings
Changing the Router’s Broadcast Channel
Adjusting the router security settings to WPA or WPA2
Enable WMM in your router settings
Disable IPV6 in your router settings
Calling your ISP and upgrading to a Higher Bandwidth/Speed
Wipe phone cache
1) Power off the Samsung Galaxy S6
2) Hold the power off, volume up and the home button all at the same time
3) After some seconds, the Galaxy S6 will vibrate once and the recovery mode is started
4) Search for the entry called “wipe cache partition” and start it
5) After a few minutes the process is complete and you can restart the Galaxy S6 with “reboot system now”
Disable phone's wifi power saving mode
1) Open your phone dialer
2) Enter *#0011#
3) Select more (top right)
4) Select WiFi
5) Turn off WiFi power save mode(enabled by default)
6) Exit and hopefully your WiFi connectivity issues will no longer be a problem

(April 11th, 2015) Anyone experiencing wifi dropping out? It seems to happen when I require it, ie browsing themes or downloading apps. It will lose wifi and the lte icon appears and the screen freezes temporarily until wifi is restored. Last night this happened like 6 times one after another which wasd very annoying.
WiFi working petectly fine connected to my as router
Sent from my Samsung Galaxy s6 Edge
Yes, I am having the same issue. WiFi drops out, screen freezes and then WiFi comes back and everything works again :/
It seems to have settled down a little now, only seems to happen when there is quite a bit of WiFi activity.
It kept happening to me while I was downloading a GPS map and also when syncing Spotify.
I am connected to a 5GHz AC router, what sort of connection are you using?
Yes,
My device has also done this also around 4 - 5 times and i was thinking could it be Smart Network Switch which is on for me.
i have also noticed the wi-fi has dropped out for when the phone is asleep and i awake it.

I don't have Smart Network Switch enabled, so it isn't that for me.
My WiFi always stays connected through sleep though.
What sort of connection are you on? G/N/AC/2.4GHz/5GHz?

I'm going to a friend's house later and will see if the same issues occur on his network.
I'll be able to do some tests at work tomorrow.
I haven't had it happen today at all :/
I downloaded Angry Birds Space 3 times this morning and no wifi drops. I was on the road and something locked up where I couldn't swipe between home screens or open the app drawer, noted I had wifi on even though I was in the car outside of a network. Didn't get to test the wifi at my friend's house but just tried downloading AB again and wifi dropped out.
This is getting annoying. Thinking I might see about going in to BB to exchange, this isn't a glitch I can live with or risk being a hardware defect. I plan on contacting Samsung to make sure they make a note, hopefully they are aware of this.
Galaxy S6 (not the edge.) Same issue. Wifi drops. Music stutters. Have to turn wifi off and back on to reconnect. Using Apple airport express.
Same thing here with galaxy s6 edge. Wifi keeps dropping out. Web pages too slow to load.
Will return the phone tomorrow.

Jesus, these phones are gitchy as all hell. I get mine Thursday. Going to mess around with it for a week and if I keep having these same problems I'm just going to return it and move to something else. I've never seen soo many issues with a new phone in both software and hardware.
If anyone can test other wifi networks or exchange phones, please report back with results.
Googling turned up a similar problem people had with the S5, some found fixes while others didn't.

I tried a few of those, others aren't necessary. I did 2 factory resets and the wifi was fine downloading 54 apps but dropped at the last one, and lasted all 55 but dropped later. I'm going in for an exchange tomorrow unless someone posts a magic fix.
The Recomhub website helped me fix my WiFi dropping problem. Thanks for the link, it really solved my issues!
5GHz Network
I've been testing this, because it is really annoying me now.
When I am connected to my 5GHz AC Network at home it drops out and freezes the phone quite a bit.
When I am connected to my 2.4GHz N Network at home, there is never an issue. Wireless actually seems to work better on this network.
So, for me at least, this problem is being caused by the 5GHz networks and switching back to 2.4GHz makes the problem go away.
This is an annoying bug, I have emailed Samsung about it, let's see if anyone replies.
My router is Simultaneous Dual-Band N (2.4 & 5 GHz) so I wonder if that is causing my issues. No idea how to remedy it at the moment.

Mine is too, but I have the ability in the router to separate the two networks, so my 5GHz network has a different SSID than the 2.4GHz one.
I've been connected to the 2.4GHz network all of tonight and done quite a bit of downloading to test it and it hasn't dropped out once, yet on 5GHz it would have done it at least twice already by now.
I cannot replicate this problem at work on the 5GHz Network. It must be something to do with the channels they are set at.
I will try and change some channels on the work network, see if I can get it the same as at home and then test again.
I have a call booked with Samsung who are going to remote my phone, hopefully they can pinpoint something
I can't even connect to my home's 5GHz, the 2.4GHx is what I'm testing.
I went to BB Wednesday and the Samsung rep wasn't aware of any wifi issue or remedies beyond what is mentioned in this thread. Of course I didn't lose wifi the brief time on their wifi network so the guy didn't know what to say other than contact Samsung support.
I tested this at my house last night.
64GB White Edge AT&T on 5.0.2
E3000 router with DDWRT
N700 Router with DDWRT
Both dual band, both running 2.4 and 5 Ghz
Both set to 40 channel width
Both with channels spanned correctly for no overlapping
Never lost connection while downloading and updating all apps throughout about 2 hours of use. Speeds saturated my broadband link (50Mbits/Sec) and never had a problem. However, I don't know about battery drain as I'm brand new and still letting everything settle for another few days before commenting/testing.
