WiFi keeps dropping - Doesn't connect to Internet - Nexus 6P Q&A, Help & Troubleshooting

Hello good people of XDA,
Bought an used Nexus 6p from a marketplace and found out WiFi keeps dropping. It connects to a network and within few seconds drops off. Doesn't even open a webpage or connect to internet for the few seconds it latches on to network.
Below are few troubleshooting steps i have tried without much luck
1. Made 2.5Ghz and 5Ghz SSID different (Completely disabled one each time and tested - Didn't work)
2. Tried connecting through Static IP
3. Wipe Cache Partition
4. Tried with all kinds of routers and 4 different internet sources at friends and family places
5. All other devices in my home are connected and have no issue. Only issue with this phone
6. Went back to stock MM ROM (6.0.0 (MMB29N)) without any luck
7. Tried with the latest 7.1.2 (N2G48B, Jul 2017) without any luck
8. Tried a few custom ROMs without any luck
9. Went through XDA forums to find if any other solution
10. Changed router setting to a specific channel
Anyone knows what gives? Is it a hardware malfunction?
Any help is much appreciated. Thanks

Have you tried flashing different radio? Not sure if it will help but I've been using version 3.75 . The latest 3.81 was having drop offs with my cellular.

Does Wi-Fi work as expected when cellular data is turned off? If not, you may have found your answer. Tried a network settings reset? Under dev settings there are a couple of toggles related to cellular/wi-fi handover. One is aggressive Wi-Fi to cellular handover, and the other is cell data always active... try reversing those. Lastly look in the phone settings menu (*#*#4636#*#*) to see if anything looks wrong, or if a different setting may work better.

It happens to me alot, Just try another rom (nitrogen for example) rarely happens to me on nitrogen.
If that don't help, try removing the password from your router (make it open without password) and test if it works (it should work) if it don't,
Try connecting your phone to the router through WPS.
If it don't help, try adding your device manually through router configuration.
Try the above and let me know the result

Can't connect to WiFi using Touch HD

Hi everyone.
First off, I know there are a million and one other threads.. believe me.. I have searched!
Basically my phone won't connect to my network. It was working fine earlier today. I've tried changing all the security settings in my router (turning off encryption for example). I've tried soft resetting and hard resetting the phone.
Nothing seems to be working. It finds the network fine, but it just says 'Connecting' then goes to 'Available' but it won't use the wifi connection.
Any ideas?
Thanks!
Have you tried connecting your device using a friends wifi router to see if this connect you
Nope. I forgot to add that I will try connecting to work's WiFi tomorrow!
Anything to try in the mean time?
Try these:
1) disable frame bursting
2) disable big packets and other methods of wifi speeding
3) force 11b
4) use WPA-PSK TKIP only
5) check if you have MAC or other access filtering
than let us know

1) Can't see any settings under my router.
2) Tried disabling gnitro (Belkin router), no difference.
3) No difference
4) Already on that.
5) Turned off.
It's so odd. Works fine with an N95.
I don't think it's anything to do with my router because like I said it worked fine earlier on in the day then suddenly stopped. The router settings hadn't changed.
Edit: I've tried turning the router security off altogether also. I really don't feel it's an issue with my router.
Tested the phone at work. It works fine.. so I don't have a clue why it's not working at home? Surely the router can't be incompatible with the phone.. especially considering it worked at one point.
Very weird! I got fed up with my router so decided to restore the factory defaults and start from scratch.. worked straight away! So I restored the settings back to exactly how they were before (using a backup file I made).. and it worked!
Just posting incase it happens to anyone else anyway.

Maybe uve tried this already but could be the fact that your home internet access point is listed as Work rather than internet, used to have an issue with mine cause of that.
I also have this problem.
Reset did not help.
Listed as internet or work did not help in both cases.
Real weird!!
I've got the same problem, all of a sudden my hd won't connect to my router.
I can connect to open networks (wi-fi hotspots etc) so i know the wifi in the phone is working ok and my partners diamond can connect ok to my router, so the router is obviously ok.
Have reset the router as well and haven't changed any settings on the phone.
Don't understand!!!!
as other users point out within other threads, it seems that Blackstone has a problem connecting to wifi networks when WPA Authentification is enabled
try to disable it. it worked for me and soem other guys
good luck!
I could connect to my router fine using my laptop.. but I still had to reset my router to the factory settings before it worked again on my Touch HD.. then I could enable WPA and everything back again. So try that!
i thought i had a similiar problem, mine wouldnt connect to wifi, kept switching itself off. figured this is normal when its connected to usb. unplug usb and it turns back on!
I own an HTC Touch HD since January and have a similar problem, only it surfaced last week. Before I had only used the WiFi connectivity briefly. The problems started after I installed an AP on my house expressively for the new PDA. The node is fully open and set to B/G/N protocols.
After a couple days of medium (couple hours per day) use the WiFi connection suddenly quit, the device would try to connect (the top bar showing the WiFi connection animation continuously) and after a few moments gave up with a dialog box stating the current network settings were wrong (even thou they worked fine a few hours earlier).
I tried several hot and cold resets, but only solved the problem after flashing a new ROM; even then the same symptoms reappeared after a couple of days of regular use. Again no re-setting would cure the problem, and now not even flashing the ROM again would work. Nonetheless, some hours latter the WiFi would connect perfectly with the same nodes it refused to before, and in very short time.
I have witnessed this cycle twice and have yet not been able to find a trigger for it, but will keep my eyes open for any tell tale signs, and post any findings here.
Hi
I used to have problem using any secure wireless connection. Then I realized that you need a personal certificate to use secure wireless networks. It uses certificate to encrypt connection between access point. I have access to a windows certificate server so I created a personal certificate with private key and import it to my mobile. Now I can login to any secure wireless network.

That solution doesn't seem to work for this problem.
Resetting the router does seem to work.
I don't get why resetting the router works.... other devices can still connect no problems before resetting, so it only seems to be aproblem with the hd.
It also sux when you are using a public router with this problem that you can't reset.
Connecting to Belkin router
Guys, I had the same problem as well. HTC touch HD used to connect to the router fine but after installing an update/upgrade it would pick the signal from the router but would not connect. (I was using WEP authentication at this time)
SOLUTION:
Go to belkin router configuration on the web.
Under security change the Securtiy Mode to WPA/WPA2-Personal(PSK)
Change authentication to WPA-PSK
Select Encryption to TKIP and enter your password.
GO to your HTC touch HD's WiFi setting and turn Wifi ON. Select your home network SSID and edit it using the information you used on the router i.e. WPA-PSK ; TKIP, enter your key/password and click next, next and finish.
Worked for me....hope it helps.
WIFI not connecting
That truly is extremly nasty.
I have the same issue - wifi found, correct password (WEP, WPA all settings) but no successful connection.
Took an old HTC 3xxx - runs immediately.
I can not reset the router - there are too many users, they will kill me then.
So I installed an Access point (Sparklan WX 7800A) to play with.
Notebooks (HP, MSI and ASUS) have successful internet access, also the old HTC 3xxx.
But still the HTC HD does not connect.
Tried "WIFI Monster" - shows the wifi, but does not connect.
(But it deletes all wifi entries easily - so you can set them up new)
Tried with NO security/password: same issue.
WEP, WPA (all kinds): no connection
There must be something to be changed in the registry - but I have no idea what & where.
Or is the wifi that useless ?????
Maybe someone can help
Ciao
Mike
I had the same problem. But the problem stopped when i connect my htc HD to my laptop and used activesync to connect to internet. After i disconnected it, open wifi and... works ok!!

I do not have the issue, but maybe you can try this.
1. Open phone dialer (Phone App)
2. Dial *#0011#
3. The ServiceMode screen will be open. When it is open. Tap on menu button on top right.
4. Select "WiFi"
5. Find "WiFi Power Save Mode"
6. Press the "ON" button to turn the "WiFi Power Save Mode" off. (It will show as "OFF" if it is off)

Ok i just found out its only doing it at home, i tried wifi and my work and it works perfectly doesnt disconnect and connect, but at home it does, though it never did it before and i didnt change or do anything to my router or my phone which i find very strange.
thanks for the help guys i appreciate it a lot, does anyone know what i can do?
have you found a fix to this yet? I'm having the same issue and getting ready to just return the phone and buy something else. My home network is fine, the other tablets, phones, laptops are having 0 issues, Yet my GS5 is either dropping or something, it seems to run horrible slow and things just time out.

No, and the reason that we don't know is that you didn't provide any useful details about your situation.
If you think that someone can do more than make a random guess implies that you think that there are only one or two possible causes. But most issues, including this one, have hundreds of possible causes. So random guesses are not terribly useful. Nor are we psychic, so the only way to efficiently narrow it down is to look for anomolies in your configuration. Which you haven't described.
You should be providing as much technical detail as possible, e.g. what is your home router model & it's firmware version and configuration details, phone firmware version, any specific error messages, any observed pattern, a logcat if you can and anything else that seems relevant.

Have you tried changing the channel on your router?
Sent from my Nexus 7 using Tapatalk
Change the router channel
Change the router SSID
Default the router comfiguration
Change the router operating mode
Update the router firmware
Move the router to a different location
Use a different router
Unplug your neighbours new 50,000 watt pirate radio station
Update your phone firmware
Buy a different phone
Sacrifice a piece of triple chocolate gnocche cake to the pagan God of chocolate and wifi
All random guesses with roughly equivalent (and small) chances of success.
Or one could try troubleshooting the issue methodically.

Hey guys,
I had this problem before, This is an issue with your samsung device and your ISP. They aren't compatible with each other.
Solution:
You must just block clients3.google.com in your modem/router. You can use Block Web Sites section in your modem/router.
Every thing has a solution.
Enjoy your device WIFI.

I have teh same issue on my S5 Cricket. The WIFI does NOT disconnect. Its connected however I don't have internet connection. Turning the WIFI on and OFF fixes the issue, for a short while until it happens again in an hour. Sometimes I slick on a link and wait and wait just to find out the darn WIFI is not connected to the internet. (probably not even connected to my router properly eg, I cant see my laptop shared drives for example).
This has something to do with saving battery or somthing. WIFI internals shut down, even though the icon on top of the screen still shows I'm connected.

Your phone thinks that your WiFi is unstable and dumps the connection to go back to 4g. Why exactly, who knows, but it's easy to turn off the "smart" network switch. Simply hold down the WiFi icon for 2 seconds to get into the connections section. Right there at the top is the smart network switch section ... just uncheck the selection box. Easy.
Lastly, people like fffft need to get over themselves. The fix for the original poster's question was easy, but since fffft didn't know it, he decided to instead attack in order to make himself feel superior. How sad and pathetic does someone have to be to troll forums looking for opportunities to attack and belittle someone else?

The issue is resolved simply by going to the advanced settings in Wifi and disabling 'Always allow scanning'.
Hope this helps.

Well I know that Smart Network is turning off wifi.. problem is that i have a fiber at home!! So what kind of problem smart network finds on my broadband?? ?
solution to wifi disconnect problem
I was looking for an answer to a different wi-fi question when I saw this.
I'm on AT&T with my S5.
Under the Wi-Fi settings I have an option for "Smart Network Switch" which says it Automatically switches between Wi-Fi and mobile networks to maintain a stable internet connection. Anytime a computer says it automatically does something for me; I typically say no thanks. I don't typically like my devices making assumptions of what I like, don't like or want to do. So I have that option unchecked. I never have an issue with the network stability once I've connected to a specific wi-fi connection.
Not sure if that will help you all or not. But thought I'd share.
so under Settings --> Quick Settings --> Wi-Fi you will find a check box option named "Smart network switch", untick it, this should take care of the problem.

Same problem
Hi, I have the same problem. Here some info:
- Device: Samsung Galaxy S5 (SM-G900F), Stock, not rooted
- Android version: 5.0
- Kernel version: 3.4.0-5640614 (2015-09-01)
- 'Smart network switch' is turned off
- 'Always allow scanning' is disabled
The problem started 2-3 days ago. When I turn on WiFi/WLAN the phone constantly turns it back off and on again. Didn't happen before, didn't change anything on the router (I have no access to it ) and didn't install a new app (as far as I can remember). I don't know if it only happens on this access point.
I made a log file (adb logcat) but am not sure if it contains sensitive information, is it save to share online?
The logcat doesn't contain any sensitive passwords.

I'm have the exact same problem.
Samsung Galaxy S5 (SM-G900T)
CyanogenMod (13.0-20151203)
Android 6.0 (Marshmallow)
Baseband (G900TUVU1ANE6)
Smart network switch: disabled
Always allow scanning: disabled
What's happening is as soon as my Wi-Fi finishes authenticating and connects, it is immediately disconnected and tries again. No other devices in my house are having any issues, so that eliminates the router. When I factory reset my phone the Wi-Fi begins to work again, so that eliminates my phones hardware. The confusing part is that I installed a bunch of apps such as AdGuard that could possibly cause an issue but everything worked and this started out of nowhere. Also, I factory reset my phone AGAIN and AGAIN, everything worked and out of nowhere while I was looking at my screen while idling, I watched as the Wi-Fi connection dropped and began the disconnect/reconnect loop...
I'm assuming it has to be a software issue because it only started when I updated to a newer Cyanogen. I'm about to test if other Wi-Fi networks have this problem and I'm also going to look through and post a log.
If anyone has any questions or suggestions that may lead to a fix, PLEASE help!
Thanks
Well I factory reset again, this time wiping the internal storage and everything is now fine. I did look at my logcat and there were Wi-Fi errors but I forgot to post them...

WiFi Constantly Dropping and doesn't reconnect

Hi,
I have a Samsung galaxy S5, and the phone keeps dropping the WiFi constantly, and notifies me every time with a notification "Sign into WiFi network" (I don't have to sign into my WiFi network), and after a while (like ~5mins) it disconnects by itself with this message"Your Device has been disconnected from this network, your session has timed out". I have done the following things:
- Disable Smart Network Switch -- No Help
- Keep WiFi on during sleep (always) -- No Help
- Always allow scanning (checked) -- No Help
- WiFi timer (disabled) -- No Help
- Forget the network and reconnect with the network -- No Help
- Tried both 2.4GHz an 5GHz frequencies -- No Help
- Changed ROM (at first it was XtreStoLite then I have changed it to OmegaROM) -- No help
- Flashed Stock ROM (firmware) with Odin (UK-ROM-OPEN) -- No Help
- Wiped everything (Data, user Data, System, ...) -- No Help
- Changed Router's SSID -- No Help
- Reset Modem's Settings -- No Help
- Changed Network Channels -- No Help
- Changed Network pre-shared key - Password -- No Help
BTW: I have like 10 devices in my Home and none of them have problem with my network, So I assume the problem should be from the S5!
Device: Samsung Galaxy S5 SM-G900F
Modem: Netgear R7000 Nighthawk
It will be greatly appreciated if anyone could give me another solution.

Just wondering, are you using a particular custom ROM ? If so maybe try another one to see if it fixes the issues.
Also if you could can you get a logcat of before and during the error occurs and i will look through it see if i can point out the problem.

Thanks for your reply, Yeah at first I used "XtreStoLite " then OmegaROM, after OmegaROM, Stock ROM, and now I'm back to OmegaROM, at first the problem solved but after I have restarted my phone, the problem came back.
I have created a logcat using adb, I hope it helps.

Does this happen on other wifi networks or just your home Wifi, as it appears that it is down fluctiuations in Wifi Signal, i would suggest changing the Wifi Channel Settings on your home Wifi Router to another channel.
The LogCat shows the changes in signal stregnth followed by a network drop, it at no point says that the Wifi Module has turned off !

Thanks for your reply, I've changed the Wifi channel like you said, but no luck, I've flashed a AOSP ROM (Cyanogenmod) and now the problem is gone, no problem at all, so I'm glad that there is no issue with the wireless adapter, I assume, that this problem is related to Samsung's Touchwiz based ROMs , maybe changing modems will solve this issue ?

In that case i would try donwloading a stock ODIN firmware from Sammobile.com and then installing that Via Odin, looks like it could be a baseband issue !
I would go to sam firmware and then choose the correct ODIN software for your device and try that !
I bet it fixes it. Also as you have installed CyanogenMOD i would try installing a different Kernel Also as this may be causing you a problem.
wifi disconnect
I had the same problem on my Gs5 on my work wifi.. was a google.client issue. This thread worked for me.. i had to do "plan b" and enter the stuff into the network config of the phone, actually used the inputs from one of the replies:
http://forum.xda-developers.com/and.../howto-wifi-drop-caused-sign-to-wifi-t2862509
Had previously tried everything you listed as well.

Wifi on Lolipop 5.0 G870A will not connect

For the last week or two I have been unable to connect my phone to wifi networks.
At first the problem would be that I was getting disconnected from any wifi network I joined, now I can't connect at all.
The wifi networks page sometimes (not always) does not detect a strong network even if I am standing a few feet away and the phone has previously connected and other APs are connected and working like my pc
If I try to connect then I get the "Connecting" status followed by "Saved,secured"
I have searched the internet looking for a fix to this and tried wiping the cache partition, forgetting the network, airplane mode toggling on and off, apps that wipe the known network list and some others including lastly a factory reset on the phone but nothing seems to remedy the issue.
From the wifi router I have tried using an unencrypted (open) connection
Now I think I may also be having problems with the bluetooth connecting in the car but I haven't had a chance to really investigate that one yet and it may or may not be related to the last factory reset.
My phone is not rooted.
Build no. LRX21T.G870AUCU2B0F3

Can anyone offer any assistance to my current issue ?

I have just confirmed that the Bluetooth in my car is not detecting my phone when it scans (the phone bt is switch on and the visible box being checked) so that's both radios with similar issues.

I just stumbled on a clue, while using an app called 'wifi cleaner' there is a feature allowing you connect to wifi networks within the app. I type in the password, authenticating is shown on the screen followed by "incorrect password".
I know the password to be correct..

I was wondering if you ever got this issue fixed?
I thought I had but the problem comes back in a different way.
Sometimes wifi connects but only connects at 5 mbps.
Now wifi will not turn on at all. ( radio button is greyed in settings)
I did find a thread on xda where some Motorola users were having the wifi off issue and it was due to a missing system file which could be replaced on a rooted device. However I don't have root on my s5 g870a and it's not likely I can get it.

5Ghz Wifi help.

Ok, so I have a us997 LG G6, and it refuses to connect to my home 5ghz wifi (NETWORK_SELECTION_DISABLED_ASSOCIATION_REJECTION=1), its done this on nougat and oreo, i figured it was something wrong with the wi-fi radio/chip, whatever, but today I looked into it more, get ready, because hopefully someone can explain this on to me...
1. If I try and connect to my home's 5GHz wifi it has the error "NETWORK_SELECTION_DISABLED_ASSOCIATION_REJECTION=1" then the network disappears completely. (Wi-Fi analyzer shows nothing on 5GHz)
2. (at this point i tried to see if it was all 5GHz networks or just my router, so i started a hotspot from another android phone (Galaxy s5) and connected to it, and BOOM, connects right away (5GHz, channel 149, 'Very good' signal strength (makes sense, the devices are within a foot of each other), ok.
3. So I set my router to channel 149 and connect to it, it connects but has very poor signal strength, despite being no more than 3 feet from the router... honestly, i'm lost now, so I figure ok...
4. I turn off the hotspot on the s5... and IT DISCONNECTS (from the home network), and then the home network disappears... honestly, what... so now i am completely lost, I just want my 5GHz wifi. please help XD
(any other device i try connects completely fine to my home network...)
(AND on top of this all, I can make a hotspot on the G6 on 5GHz and it works just fine, devices connect with proper speed and 5GHz band!)
edit: If i am connected to ANY wifi network (5GHz or not) the 5GHz home networks shows up, but it still cant connect, when i disconnect from all networks, it disappears again)
TEMPORARY SOLUTION:
Disable WiFi
Go to the service menu (us997: *#546368#*997#) (h870: *#546368#*870), goto field test > WiFi test > select 'core both'. Press start
Go to the root of the service menu again, goto FTM test > select 5.0GHz, press start, you should see a 'Start Successful' message.
Exist the service menu enable and disable WiFi a few times, and that should fix it... Thanks to: cabal06ba for solution!
I don't know the details but when I unboxed and rebooted G6 for the first time, it didn't catch the 5 GHz signals either. I've searched some and found out that this was a common issue. Some people said "restoring the phone to the factory defaults" solves the problem. I've immediately done a restore process and 5 GHz is working like a charm now.

I've reset my phone a bunch of times between updates and rooting mishaps, and nothing (not in the mood to do it again), i will try resetting network settings.
edit: resetting network settings didn't do anything...

Network Settings Reset didn't do the trick for me either but with help of your first post edit I've found a fix (long-term functionality not yet approved):
1) Go to phone and dial *#546368#*870# to enter the hidden menu
2) Go to field test > wifi test > OTA
In my case it was disabled and enabling solved the problem! (actually I don't even have a clue what this setting is exactly for, found out through trial and error)
3) Then went one step back, entered FTM test, set 5GHz, started and boom, "start successful"! (before it had failed)
4) Finally I went back to regular WiFi-Menu, was switched off so had to turn it back on, no networks, off an on again, 5Ghz was back and still is after several reboots + resetting network settings once again to double check.
Hope that works for others as well!
Don't have an WiFi hotspots that are 5ghz near me now, I will test later, but I have tried using the WiFi test to enable 5ghz before and it didn't work
Edit: Well it said start successful, so hopefully it worked (BTW if you are on a us997 device replace the 870 code in the number with 997)
Edit 2: Devcheck reports '5Ghz support: yes', previously it reported no. Thanks!
Edit 3: Still does not stay after disabling WiFi
Also Even after a factory reset, still stuck on 2.4G

Without a registered SIM card, wifi works at the lowest common denominator on the G6: 2,4ghz channels up to 11 and 5ghz 36 to 48.
So where mobile signals are too weak, wifi is also limited.

I have a registered SIM, I'm on Verizon, Mobile signal is weak everywhere but standing outside a tower because its Verizon...
Once the phone had been registered with the provider, wifi is fully supported even w/o mobile network. Provided the SIM stays in and you don't perform a factory reset.
I had to get a nano sim in order to use my G6. It "unlocked" my G6's wifi, but i continued to use my trusty S5 for a while, so the G6 reverted to bad habits.
Part of the G6's antennae are in the metal frame, but i don't know which ones. These work best while kepping gripped, with no insulating case. While not bridging them all electrically with your hand, which is no good.
The first device with frame antennae, the Iphone 4 had to be modified for this reason. The first batch required the use of a rubber case or frame.
In my case, 5GHz did not work as long as the bootloader was unlocked. Even after I reinstalled the original OS via LG Bridge / Repair. Once I re-locked the Bootloader again, the LG6 connected to 5GHz.
I hope there is a way around this. Probably this behaviour don't apply to custom roms.

I'm still having the same issues, doesn't matter if it's stock ROM or custom , really don't want to relock my bootloader.
