Samsung G935F - wifi problem - Samsung Galaxy S7 Edge Questions and Answers

Hi ALL,
I noticed that my My Galaxy S7 Edge's Wifi constantly keeps turning off and on for some reason! does anyone else experience this on their phone?
Thank you.

Is their any known wifi issues on Galaxy S6 Edge (international variant)?
Can anyone help.

Could you be more specific? Do you have WiFi turned on while your screen is off? Maybe post your advanced WiFi settings so we can see if there is anything off

Recently it happening to me also but don't know the solution.

The following things have generally helped:
- Set DIFFERENT SSIDs for 2.4 and 5GHz bands. I have found that most devices and routers do a terrible job dynamically switching between the networks if each as the same SSID - I think the chipset recognizes the SSID and constantly jumps from one band to the other depending on which had the strongest signal.
- Disable the bluetooth and wifi SCANNING feature (not bluetooth itself as one of the prior posters cited). This setting is found in "locations" and allows your phone to scan for recognized wifi and bluetooth networks even when wifi or bluetooth is turned off to pinpoint its location. Given that bluetooth only has about a 50 ft range, its puzzling why the bluetooth scanning is even an option
- Set the channel width in the router to 20 MHz or 40MHz. Some products can't recognize the 80MHz channel widths (my old S5 couldn't recognize my travel router if I had it set to 80MHz. Note that this may slow down your connection.
- Disable Smart Network Switch (in Wifi Advanced settings) or other similar setting that dynamically switches between Wifi and mobile data depending on network access
- Get 802.11ac-capable router. This may be less of an issue now, but for a couple years after the ac standard came out, a lot of ac clients would have issues with legacy non-ac routers. Obviously not ideal.

I don't have problem with my S6 Edge connecting to my home wifi.
I tried to disable some setting as Joku suggested and it minimized the wifi connection drops. I noticed that my S7E connected most on my 2.4GHz

same problem with my S7 Edge

Having this problem only with certain routers (other phone models stay connected just fine). The router only has 2.4 GHz, and bluetooth is off, scanning is off, smart switch is off.
Router is a Verizon FIOS Router Actiontec MI424WR-GEN3I.
US T-Mobile GS7e, on latest firmware.

wifi issues on N4 possible fix?

for those with wifi 'broken' try to change your router settings to WPA2 personal (TKIP+AES) that seems to work for me now,
other settings 'broke' the wifi
this might be just an issue with must me and my router
*spoke too soon: still broken, it only works certain times, mostly it just spins when i try to connecto to online
the wifi icon keeps flashing a black dot... that means the wifi is NOT working right? it should be just a solid blue bars?
on wifi advanced settings, WPS Pin Entry - what is this and do i need to enter that pin on my router?
still no luck with wifi on my network after flashing back to stock 4.2 from 4.2.1
same 'broken' wifi
might be this phone's wifi hardware is incompatible with wDDRT router?
Firmware: DD-WRT v24-sp2 (10/10/09) std
my other wifi devices work perfectly fine, so im really stumped
in phones advance wifi settings it has this WPS entry - what is this and is it somehow not allowing me full wifi?
i can view playstore,, it checks and loads my gMail but it won't connect to websites
it takes so long to download and install apps from playstore, i have to hit cancel, redownload, reinstall to get it working,etc. its not 'instant' like normal 20Mbps wifi should be
ran speedtest.net app and it wont connect to any servers
if anyone has clues to why my wifi is broken, please PM me thanks
it get a blue 3 to 4 bars on wifi signal but it keeps having this 'black' dot flashing in that wifi signal bar, (what is that?)
shows connected to my wifi at 72Mbps at good strength
I found my solution: in my router I unchecked the option WMM (Wi-Fi-multimedia)-settings (2.4GHz b/g/n). After I activated it, my data speeds increased enormously. Try it & report!

My n4 will not connect to any of the WPA2 AP's around here.
I have the opposite problem. I can connect to my WPA2 router at home just fine but cannot connect to the WEP wifi at work. Well, not reliably. I've gotten connected twice, but was unable to recreate the conditions.

I had speed problems with my 5GHz band at home. Connected, but couldn't get over 1Mbps on my 30+ connection. Connected to the 2.4Ghz band and I get significantly faster speeds. Haven't had problems connecting though.

I've noticed similar behavior, seems like my 5ghz signal strength is much weaker than my 2.4ghz signal according to my n4.
So this n4 is picky about. Certain WiFi networks.configs
Sent from my Nexus 4 using xda premium
Sometimes, my N4 loses wifi connection at work. It's inconsistent. My work wifi is open but MAC filtered.
There have been 3-4 times when I noticed that it lost wifi connection. I had to turn off wifi radio and back on to reconnect.
OTOH, connection to home DD-WRT wifi router is rock solid.
Set lease time for as long as possible, it normally this is 2 weeks..

can you test to flash back CWM recovery and test again the wifi ?
Hello, I am also having problems with WIFI. I've tried a lot of things (change the router configuration, the cellular exchange kernel, etc ...) but I could not fix this problem. Can you give any more ideas? I've even thought about buying another router but can be giving the same problem.
I used my wife's phone as a router and it works normally, but when I connect directly to the router from home and he trasfere data only for a few moments and then transferring data, although still seem the symbol of wifi connected.
I found changing a setting on the Nexus 4 seems to have remedied most of my WiFi issues. Forcing the WiFi frequency band to 2.4GHz only instead of Auto appears to have done the trick for me.
In WiFi if you select Settings and Advanced under Wi-Fi frequency band there is an option to force 5GHz or 2.4GHz with the default on Auto.

Wi-Fi connectivity issues

Somewhat of an odd issue with Wi-FI
First the phone is a 100% stock (unrooted) Sprint issued Galaxy S5.
Access point is a Cisco 1142 in Autonomous mode running 802.11n (2.4 & 5ghz with a 40Mhz extended channel in the 5Ghz band). Both IPv4 and IPv6 (utilizing auto configure) are on my network.
Three laptops report up to 300Mb/s connectivity and work flawlessly
Three iPhones work without any issues
Two iPads (Wi-Fi only) also work without issue
Galaxy S3 work without issue
HTC EVO work without issue
The Galaxy S5 connects and works fine for a random period of time, seems to be typically between 1 and 3 hrs and then simply stops communicating, I've tried a static (IPv4) address but to no avail. Sometimes I'll find that only the IPv4 stops working but IPv6 continues to work or vis versa.
One thing I did note was the S5 never reports a speed higher than 144Mb/s regardless of the signal strength. I haven't tried disabling the extended channel on the 5Ghz band, maybe the S5 has a problem with that?
Lastly connecting to an 802.11g AP seems to work reliably.
Any thoughts/suggestions? I'm not opposed to rooting the phone if there is a known issue that is solved by modified code.

Tried disabling Smart Network Switch in WiFi settings?
Should have mentioned that -
Under Wi-Fi advanced
Network notification - unchecked
passpoint - checked
sort by - signal strength
keep wi-fi on during sleep - always
always allow scanning - unchecked
smart network switch - unchecked
Wi-Fi timer - all times unchecked
-TL
The access point "had" two SSIDs being announced, I took one off and the stability problems seem to have gone away, now to figure out if I'm announcing the second SSID incorrectly or something else is going on.

You might be onto something, based upon what I've found and my understanding of Wi-Fi there should be no issue with putting the same SSID on both radios; however I've found that the S5 seems to be switching back and forth a lot and is failing whenever its on the 5Ghz radio. I have since turned off the 5Ghz radio (of course that reduces my throughput to 144Mb/s on Wi-Fi vs 300 but I doubt I'll see a difference).
I've seen some various comments about 5Ghz not working properly for some, I don't know if this is a real issue or not.
Also keep in mind my 5Ghz radio was set for a double wide channel (40Mhz vs. the small 20Ghz) enabling 300Mb/s.

There's no issue until you have a device(such as the s5) that sees both bands, people do this with public WiFi as well, they put up a malicious hotspot with the same name as the public one. I would give your 5g band a different name that's what I do, its just said for 2.4 and ssid-5G for the 5.

Wifi disconnects and reconnects constantly

Hi,
just had the phone for an hour and almost right away after first setup the wifi radio disconnects/turns off and re-connects/turns on automatically every 20 seconds or so. No matter wich network I try.
Working fine with my S7 Edge laying here beside me, never had problems. I have three different networks around me I can try out.
Anyone had the same problem? I can find som info about this exact issue for the S7 Edge for some, but no solution from that works on the S8..
N
this is an old problem S7 had
you need to toogle in settings > connectivity > wifi > advance > smart network swithc OFF
i think this was - but dont remember well since it was a while ago - but basically you need to turn off the option of phone switching between phone and wifi data
Having the exact same problem with my Ubiquity wifi network (ie, not some janky cable company router) with my just-booted up S8. Smart switch was off by default, and after switching it 'on' and back 'off', no change.
This was the first thread I found on the topic, will update with any solutions.

Try downloading wifi analysis app and see what it's picking up. Maybe you could try changing your wifi channel if it looks low?

No this has nothing to do with the routers or access points. I am 3 meters from the AP, its at 100% signal rate etcetera..
This has to do with Samsung and the software.

As I wrote I've tried all that I'm afraid. All the things that was recommended for the trouble on the s7.
have u tried going to a free wifi spot (starbucks, mcdonalds) see if the issue persists - maybe is your router refusing connection

As I wrote I have three different wifi to test with but yes makes no difference. This is a well known but not solved problem with Samsung phones.. three different makes of manufacturers, different settings with a/b/g/n and all show the same problems.
I also installed the small new update today for the firmware. Still same problem.
I'm guessing I'm about to get a replacement phone. I'll try that on Monday.
I'm not seeing the same problems with public wifi as I am with my Ubiquity Unify AC AP Pro access points at home - definitely weird.
When it is connected, I'm getting my usual 100mbps speeds, but it continues to drop regularly (not the every 10secs it did when I first powered it on, but every minute or so).
One thing that was mentioned was changing channel bandwidth from '40' to '20'... I don't see anywhere to do that on the S8?

Doesn't that mean on your router?
By changing the broadcast bandwidth from 40 to 20 you will increase the signal produced (same power is covering less channels)

I had this happen on a UniFi UAP-AC-Pro network with my S8 as well. I turned off Nearby Device Scanning on the S8 under Settings-> Connections -> More Connection Settings and that seemed to fix it. Strangely, I did not have the issue on my home network which has a single UAP-AC-LR access point with an otherwise similar configuration. Not sure if this setting change was really a fix, or if I just temporarily got lucky.
If turning off Nearby Device Scanning doesn't work for anyone, it might be worth playing with other settings within your network such as Band Steering. Some of these require turning on advanced features within the UniFi controller. Also I would be curious to hear whether those who have issues are on networks with a single access point, or larger installs with multiple access points.
Very recently got the Samsung S8 and I'm having some wierd WiFi issues. When connecting to the network everything is fine i get almost maximum download/upload speeds(500/500) from my UniFi AP-AC-PRO. But after being connected for awhile 30-60mins the speed drops to around 30mbit downstream and upload around 200mbit. If i disconnect from the Wi-Fi and instantly reconnect i get full speed again. I've tried switching settings in the ap, went from everything on auto settings to static channel/transmit power and been trying vht40/80 but makes no difference. If i have smart network switching on i get disconnected and put on LTE instead. All my other devices have blazing WiFi speeds as usual. I'm gonna try turning of nearby device scanning and see if that helps.
I started a thread in the ubiquiti UniFi forum as well but i cant link that here(not enough posts on this xda account)

I'm having the exact same problem as you. Wifi connects at full speed at first, then after a while speed drops. Has gone down to 1Mbps numerous times. Disconnecting then reconnecting fixes it for a while then it starts all over again. I'm connected to a TP-Link AC1900 running dd-wrt. May try going back to stock firmware on the router to see if that helps.
So has anyone come up with a permanent solution to this? I'm in the same boat with my ac-ap-pro and s8+. Disconnects every 20 seconds or so.

S8 Internet connection may not be available issue

Just got the S8 and I have 3 Wi-Fi access points at home to cover the whole house. My S8 has been registered with the passwords for all of the APs but it continually rejects the connections with an exclamation mark after the WiFi icon having connected and then shown a message that the Internet connection may not be available. The Internet connection is available as other devices are connected and using it perfectly. If I switch the Wi-Fi on and off and reboot the S8 the issue corrects itself but I should not have to go through that nonsense every time I come home and want to use my Wi-Fi. I have explored the advanced options on the connection settings and they appear to be quite limited (DHCP Etc). Is there some way to solve this issue? I have no problem with other android devices connecting to the same hotspots. Any ideas that might lead to a solution would be appreciated.

I had this problem when i first got my s8 from vodafone but when i got this latest update it's been good no issues with internet anymore.
I have this problem as well with my S8 from Verizon. Worked flawlessly for a week and them today I get this error. Very frustrating. I know the SMG955U from Verizon is already unlocked but is there any way to put the International ROM on the phone seeing that the Verizon and the International are the same?
I've tried all the resets etc and the WiFi connects but I get the 'Internet connection may not be available' message.
Update 27/04/2017
Thanks for the reply. My S8 developed some interesting issues including the switching on of 'do not disturb' mode intermittently and along with the Wi-Fi issue the mobile data was failing in areas where a full 4G signal was present. Rebooting, resetting etc did not resolve the issue and I returned the phone to CPW for advice. The staff at the Glasgow store wasted no time and exchanged it on the spot after some negotiation with their technical service centre. Full marks to CPW for the prompt service and I can report that all of the previous issues have now been resolved with the replacement handset. I thought it worthwhile to post this information so that others who experience similar issues may be able to get a similar resolution.
Poor WIFI performance
I also have issues with the wifi of the phone, /i will get the terminal replace some time today or next week.
1. WIFI keeps disconnecting, actually it's flapping connct&disconnect for 5-10 min until it finally connects, on this matter I have seen on the acces point that it tried to allocate an ip from an unknown without asking DHCP server for an IP renew it actually tries to alocate itself the last known ip, and clearly disconnects because of lack of internet access, this happens normally as power saving mode is on, disabeling power saving and assigning a static ip on the phone seems to resolve the issue.
2. poor wifi signal... no fix for this thus far
- i have 580Mbps speed connection on my S5 and only 120-240Mbps on my S8, steaming not working and connection in general very bad, time ots and stuf, although I position myself at 10cm away from the wifi router antenas i only get 540Mbps signal, although I have an AC1750 router , s5 gets 840 in the same spot... I think the modem(that is part of the Exynos chipset) does not work wekll with Atheros based AP´s , I have an Archer C7 with 2.4ghz QCA9558 chipset capable of 450 Mbps theoretical speed, but only uses 2 antenas as s8 only has 2 from my knowledge and reaches a max of 140Mbps(should of connected at 300Mbps at 10cm in theory ) with the s8 and QCA9880-BR4A on the 5ghz side of things with a theoretical speed of 1300Mbps should work at 866 with the S8 because of the 2 antenas of the S8.
phone changed 90% of problems fixed
Hello, just got my phone replaced, tha new unit has way better wifi signal considering I hace atheros router and the phone has broadcom 43xx chipset... worth considerign changing to a broadcom router...
Hi,
I have found a solution to this problem.
1. GO to wifi settings
2. Forget the wifi network
3. CONNECT AGAIN BUT BEFORE CONNECTING GO TO ADVANCED OPTIONS AND CHOOSE STATIC INSTEAD OF AUtOMATIC. Enter in the ip address etc and connect.( It requires to be entered manually) Problem will be solved.

Change the DNS...
Hi there..
I had just the same problem with s8 plus and s7 edge(after updating to android 7.0), it kept saying "internet may not be available", I changed the DNS to 8.8.8.8 and tue problem solved. Go to SETTINGS》WIFI》SSID》MANGE NETWORK》change the IP SETTINGS to STATIC》then change the DNS1 to 8.8.8.8 hit save and you are good to go.
Sorry if there are any mistakes. I am new to XDA and not good in english.

There are 3 WIFI Router that covers my house. I have problems saying internet might not be available every time I connect. This is very annoying. Other Phones in the house like Iphone do not have the problem.
What I noticed is that the IP range of my router is:
192.168.1.1
But my S8 says he is connected but the IP is
192.168.0.100
Anyone have same problem?
Thanks!

Just got the S8 and I have 3 Wi-Fi access points at home to cover the whole house. My S8 has been registered with the passwords for all of the APs but it continually rejects the connections with an exclamation mark after the WiFi icon having connected and then shown a message that the Internet connection may not be available. The Internet connection is available as other devices are connected and using it perfectly. If I switch the Wi-Fi on and off and reboot the S8 the issue corrects itself but I should not have to go through that nonsense every time I come home and want to use my Wi-Fi. I have explored the advanced options on the connection settings and they appear to be quite limited (DHCP Etc). Is there some way to solve this issue? I have no problem with other android devices connecting to the same hotspots. Any ideas that might lead to a solution would be appreciated.

I found a quick work around on how to fix this temporarily until Samsung issues a patch.
just turn off 5ghz SSID broadcasting and you should be ok for now.
here is a quick how to video i made on just in case.

I'm having a very similar problem with my home WiFi and my Verizon S8+ I bought from Samsung's website. I've tried switching from DHCP to static and entering all my info. No luck. I've also switched my dns1 to 8.8.8.8 and dns2 to 8.8.4.4, and my WiFi router is set to 2.4ghz only. No success in resolving the issue. Currently my phone will show the "internet may not be available" with the added exclaimation point for a few minutes when first connected, then the exclaimation goes away and I'll have regular full speed internet for around 25-45 seconds before it goes back to a non-internet state. Any suggestions?
Try changing in your router the security setting. If your using WPA2 AES/TKIP, change to just WPA2 TKIP and see if this works for you...
I was having the same exact issue for months. I changed to TKIP only and have been rock solid ever since. No more ! at all... I'm gonna switch to just AES today and see how that works.
Changed to WPA2-AES and within the hour had ! back and no internet. Went back to TKIP and rock solid again. Looks like a possible bug with AES to me. Sticking with wpa2-tkip setting for now.
I'm having this same exact issue.
Anyone who knows what to look for to fix this, what info or files do you need from me? I'm at the end of my tether with this ****
I am having the exact same issue on my galaxy tab s2, even on the replacement. Due to the being such an intermittent problem, it wouldn't do it when Samsung support checked it out...
This happens on both 2.4 ghz and 5 ghz frequency for me. I've tried downloading a wifi fixer, I've reset network settings, and turned off nearby device scanning. I've also tried doing what a forum suggested by changing the ip settings from dhcp to static but it wouldn't connect to wifi at all. Not sure what else to try...
I read that it may be due to nougat 7.0 software. I was suggested by Samsung to first put the tablet on safe mode (this disables third party apps, and would reveil if an app was causing the problem) but the problem still persists. Also did a hard reset on the first tablet I had but it still done the same problem...
I always thought that this was a is problem in 7.0, and was addressed in 7.1. Hopefully, when the next major update comes out, this issue will be resolved.
Oh come on Samsung!
It's been 4 months since the first post and still no solution.
And it's a basic wifi connection!
Internet may not be available! = Samsung may not be available
Heya all. First post I guess
Edit: Gah it was the second. I have to controll myself better and not spam.
So I had the same problem and tried more or less all.
My "solution" was to disable the firewall on the router which means some settings/security there was triggered. My guess is that it's the "Smart Network connection" that trigger it if the phone have both poor Wi-Fi and 4G. It then jumps back and forward = firewall detect strange behaviour and block. That's why there are so many strange "fix" related to the router - hidden network - no security - disable 5Ghz and so on.
Can someone please test asap as I have a plan But if it's not this to test

WiFi unstable

WiFi is very unstable when you aren't next to the access point. It keeps switching from WiFi to data connection.
Furthermore, when gripping the phone from the upside without a cover (near the camera), the WiFi connection will not work anymore.
Someone is experiencing this problem?
same to me
WiFi works normal here... No deathgrip
Maybe you can try enabling Aggressive WLAN to Cellular handover at developer settings under the networking tab to fix your issue

Well, the problem in my case was that I have two access points with the same name at the two sides of the house, and from my room the second AP has a better signal, but it had some trouble and it wasn't working, so the phone wifi was switching from the first to the second continually.
However if you hold the phone from the upside, there is a very strong loss of signal. A workaround is to use a case.
I can say that wifi antennas of this phone are not that good, like the iPhone 7.
My previously Xiaomi phone had a better wifi signal on very distant access point.

I agree: not a solution.
I've changed ssid of 5Ghz wifi (now is different from 2.4) and wifi don't disconnect random anymore.

Yes, the same SSID on different AP / technologies makes only troubles.
Never use the same name for 2,4Ghz and 5Ghz. Unfortunately many providers have the routers that are configured this way.

I've configured my router with same ssid to use band steering (i can't post link: search "band steering avm" from a search engine)
That technology do exactly the trick: switching from frequency bands, but even disabling it Mi A1 doesn't manage WiFi correctly and don't suppose to do that!
Hi Guys
Is there a solution for unstable wifi connections.
thank you
