WiFi connectivity issues after Lollipop factory flash - Nexus 5 Q&A, Help & Troubleshooting

Hi there.
I tried searching the forum first before posting but couldn't find anything else that was the same issue.
I flashed the Lollipop factory image (LRX210) onto my Nexus 5. Everything works fine expect when connecting to my home wifi.
The phone acts like my home wifi is a public connecting and is always asking me to "sign into network". But if I ignore this message, disable my data (because Lollipop now defaults to using mobile data when wifi connection can't be established) the wifi seems to work fine and I can load webpages, use apps etc.
My wifi router is an Apple Airport Extreme 6th Gen and I've tried changing the channels for both 2.4ghz and 5ghz
From searching around I've seen various posts about wifi problems with the Nexus 5 after Lollipop flash/upgrade, but noting I've read seems to be the same issue as me.
Anyone else experiencing this issue, any ideas on how to fix? Or should I wait for Google to release an update to fix other wifi bugs and pray this fixes mine too?

I managed to find a fix for me which worked!
I flashed the radio img file from the ktu84q build and voilĂ , no WiFi problems at hone.
Sounds like an issue with the lollipop radios so hope that gets fixed at sine stage

[Q] No Images when on WiFi?

I am running stock Kit Kat except that i have my phone unlocked and rooted.
What is happening is that when i am connected to wifi i am unable to load images on the play store, or any browser. Games work, video works music works, but images wont load.
I have no problem on my nexus 7 connected to wifi or any other device i have ever had. If i disconnect from wifi and use cellular it all loads just fine. Can anyone lend a hand on this for me?
Thanks
update: turns out that you tube thinks i have no network when on wifi, but other apps seem to work and think they have a network just fine.
Update: must be something to do with the router, when i connect it to a wifi hotspot it works fine. ???? thanks anyway.
Doesn't seem to be an issue with the radio on the phone, especially if you can connect to other hotspots without issues. Factory reset the router, that should fix the problem.
Try checking to see if you have any adblocking on your phone and disable it and try loading pictures up.
Thanks I'll give them both a try.

OK so no add blocking and that couldn't be the case as you tube and hangouts and google+ all behave as if I have no network. I will try the router reset and cross my fingers. I just updated the firmware on my netgear r6300.

Ok after testing resetting the router gave back a small bit more but non of the Google services act right such as no images in YouTube but I am at least not getting a no network error. This same issue now exists with my nexus 7 2013 after installing kit Kat. Now I am pretty sure its not my hardware, instead its the modem that's installed with kit Kat on both devices.

Nexus 5 Wifi Issue

So I've had my Nexus 5 for roughly around a month and I hadn't experienced any issues others have had with wifi not connecting until now. My N5 will show im connected to my home wifi with full bars, but going into quick settings shows it to be orange. Suggesting there's no data transfer, I cannot use any internet based apps with wifi. I've tried some suggestions, switching my router off then on, rebooting the phone, turning some settings off in the advanced panel in wifi settings. All have failed.
I was just wondering if anyone else has this problem and if anyone has a fix to it.

There was a thread around here somewhere that suggested turning off your mobile data helped fix this problem, I think it was in the N5 General forums.....here it is:
http://forum.xda-developers.com/showthread.php?t=2550690
Don't know if it'll help or not, just saw your thread and had just looked at the other one, figured I'd toss it out there.
Thanks for the reply, just tried that solution but still no luck.
I have a similar problem except that there are phases of wifi not working.
Sometimes I would have around 20-30 seconds of WiFi not working and there would be no data transfer.
Speeds are still fast when it is working however.
I played a little with only using mobile data and no wifi, and everything worked. (Small sample size however).
Seems like this is a WiFi only issue.
So somehow overnight the wifi has managed to fix itself, will report back if the problem returns.
The issue with the wifi returned unfortunately.

Don't know if you've tried this but change your WiFi frequency band in advanced setting to either "5 GHz only" or "2.4 GHz only," whatever your router uses. Might be worth a try.
Thanks for the help, but I've tried changing some settings in advanced wifi settings but it hasn't worked. Even what you recommended I've tried that before and it didn't work.
wifi issue
Also I have the same issue - Im connected to router by wi-fi, home and work and time by time (5x a day) wifi stops working. Wifi is enabled in settings, but there is no connection. Restart the cellphone helps, but after that, maybe an hour, it appears again.
Issue was in 4.4 and still appers in 4.4.1.
Yet did not found how to solve it.
I have the same issue on my gnex running shiny 4.4, but I also had the same issue on 4.3. Tried the wifi options, nothing worked. Unfortunately, no solution for this device that has to last one more week. The double swipe down and tapping wifi gets the connection back, but it is only a work around.
The N5 connects seamlessly to my home and work wifi. A few days ago, I flashed the hammerhead factory image, TWRP and the 4.4.1 update.

Hey,
I have the same problem with 4.4.2.(factory rom, no root or not unlocked). Sometimes the wifi not works and get orange. I must put airplane mode to fix it. Its annoying.
But as well happens to me:
When I go out from office or home (where I have wifi connections saved in phone) the phone automatically switch to data plan from carrier. But when I come back the phone stays with data and there is not automatic switch to wifi. Sometimes it help to put wifi off or always airplane mode on/off for a while.
I do not know if it is normal behave of android but I would like have automatic switch to wifi.
I tried to change wifi details (changing bands, etc.) but not helped.
Please help. Thank you.
Is custom ROM or kernel will fix it??
For some unknown reason, as soon as I updated my router's firmware, the problem disappeared.
Updated Android 6.0 solved the issue

So I had the unfortunate experience of having my wifi go down while on vacation and for 3 weeks I spent a good chunk of time wiping and reinstalling multiple versions from Cyanogen, Paranoid android and 4.4 - 5.1 to no avail. I just did another factory wipe today and installed the new Android 6.0
The Finger Pointing Game is OVER
Read through 30+ pages of other android users with similar experience and some people send their units back to LG and some even managed getting a new handset. There was never any hardware issues with my unit I just couldn't turn on the WiFi but after the install WiFi works? Guess next time you push a software update to our Phones CHECK YOUR SH*T google and Maybe DON'T Take 3 months to FIX your F*CK Up.
I have a similar issue. Since Lollipop my phone almost never automatically connects to my WiFi anymore. What's wrong?

Lollipop Wifi Issues

Is anyone else experiencing wifi drop outs since updating to lollipop? I can't stay connected to my wifi for more than 5 minutes without it dropping out. When i go into wifi settings it keeps saying authentication problem even though my password is saved. It will suddenly reconnect when it wants to only to drop the connection again minutes later. Ive tried going into my router settings and switching channels but that did not fix the problem. If anyone else has had this issue did u happen to find a fix for it?

Yes I too have this problem. Wi-fi can be fine for a while then it suddenly drops out and when I try to reconnect to my home router or any other it simply says authenticating then saved but never reconnects. Then randomly it connects when it wants. Tested the connection on my S4 with no problem but Nexus 7 (2013) had great wifi before the Lollipop arrived. Wish I had stayed with Kitkat. Cant find a fix anywhere so now my nexus is as good as useless to me. Very very disappointed Google member! ????
Hm do you guys also have a slower Internet connection after upgrading to lollipop? Somehow my Internet was lot faster on KitKat
I've deffo got a reduced wifi range since updating to Lollipop and it does seem to be a little slower also when data gets flowing
I'm too after lollipop upgrade I have lot of wifi and network connection lost in mobile 3g....
I flashed the kk radio and don't have anymore issues. Yes, kk radio with lollipop works nicely. Seems the issue is the lollipop radio.

The 5.0 factory images don't come with a radio.img, so we're presumably still using the same radio - are you using a cellular nexus?
Isn't WiFi a kernel thing rather than radio? My N10 which is having WiFi issues on Lollipop has no radio

After Lollipop (5.0), I had problems with my wi-fi connecting with my same Netgear N600 router/system I have always used. My phone would see my router both 2.5 and 5 GHz, but I would input my password and my phone would connect for a split second, then disconnect. I was able to connect to other open networks at church, stores, etc. by just inputting the password and would connect and stay connected. The phone also remembered passwords.
This seems to have worked for me:
I have McAfee Mobile Security and turned off web security and wi-fi security temporarily.
From Settings<Wi-Fi click 3 dots upper right corner<add network and manually input the network name<changed security to whatever you are using WEP, WPA/WPA2 PSK, etc< then input password <and save.
I entered the information for my 2.5 GHz and the 5.0 GHz strated working too.
Hope that helps someone.

I will definitely try that if I can get it to turn on. It just sits there for ever saying turning on WiFi and won't actually turn on!

Never used 12 or 13 anyway (still had problem on 11and lower. I use 5g while using the kk radio, I have not tried with lollipop radio. Essentially, let lollipop works with 5g as long as you have the kk radio installed. Thanks for your help, it's really amazing it hasn't been fixed by Google yet.
tried kk radio last night and it was deffo better than the lollipop radio but still got alot of dropouts which never happened on KK, had to turn wifi on and off again to get signal back
Possible solution to wifi speed issue.

Try changing router dns, router wifi channel uninstall Adobe Air and anti virus.
I has having a 30 second delay getting a website to pull up or data access in all apps.
I did a bunch of things all at once so Im not sure which of the 3 fixed it.
I removed Google dns from my router.
Changed my wifi channel from auto (was on 1) to 6. Most of my neighbors were on channel 1. (interferance maybe(.
Removed AVG
Removed Adobe Air.
Yes I should only do one thing at a time but I was getting pissed.
Both my Nexus 5 and Nexus 10 had the same problem. My Nexus 5 worked perfectly fine on LTE though.
So I think it was probably the wifi channel or the dns server settings had gotten messed up somehow and changing these cleared it up.
I'm having the same problem on my Nexus 7. Wifi is slow and drops out every few minutes since I installing Lollipop. I factory reset and flashed the official 5.02 and it didn't help. Wifi was perfect on Kit Kat.

[Q] wifi and mobile network keeps disconnecting

Hi
i'm having some issues with the radio on my Nexus 5, it startet after i upgraded to 5.0.
I did this by first deleting all user data (i use stock fw, no root), then by flashing the factory images with fastboot.
What happens is that wifi keeps disconnecting very often, like every 2-3mins.
if i turn wifi off, the same dropout happens with the mobile network..
I thought this was just a bug that would be fixed in later releases, so i waited.
5.0.1 OTA popped in and did not fix my issue, so i did a factory reset (read that in 5.0.1 android resets more thoroughly).
Still it keeps disconnecting.
now when 5.1 was released i flashed that image (didn't edit the flash-all.bat file so there was another wipe), it still disconnects.
Can anyone help me diagnose this problem (i can try to do a logcat?) can i flash the old radio from 4.4 safely?
is there anyone having the same problem like me?
I don't have quite those symptoms, but I do have a Wi-Fi problem, ever since 5.0. My Wi-Fi connection drops at random times. You can see the drop outs on the battery page, and it just stops whatever network activity was happening at the time. If I'm using Chrome, I know it's going to fail when the progress bar goes to about a cm then stops. If I toggle Wi-Fi off and back on, or sometimes if I simply wait for about 30 seconds, it works again. With 5.0.1, I was using the 4.4.2 radio, which was a lot better, dropping the connection a lot less often. I hoped 5.1 would fix it, and it's better, but it still happens sometimes.

My problem has, though it is worse on some networks. It's worse on my own home router, for example, which is an Asus RT-N66U running Merlin firmware. It happens less often here at work, but it has happened here. Both of these networks are 2.4GHz only. It happens just infrequently enough that I can live with it, but it's annoying.

My N5 WiFi is always rock solid on baseband M8974A-2.0.50.2.22 on 5.02 Euphoria.
I connect regularly to an Asus RT-AC66U router @ 2.4GHz running Merlin . So I doubt its' router related.

Well, i only use wifi at home so i'm not sure.
I've been testing with wifi off at home to rule out wifi, but it keeps disconnecting on mobile network as well.
It doesnt happen during calls, just while browsing etc, using mobile data.
It also keep switching between LTE (with low signal -117dB) and Hsdpa (better signal, -117) so i tried locking it to use only GSM/CDMA, that didn't help either.
Now i tried setting up my old router to try anoteher wifi network, no luck..
Guess i must try kitkat radio, see if that works any better
edit: that didnt work either

I've been trying to isolate this problem forever, and I'm starting to think it is something about my router, after all. Could you possibly post the settings from your Wireless General and Professional tabs in the Merlin firmware?
I now have a perfectly stable phone. Nexus 5 with 5.1.1, rooted, TWRP recovery, Xposed alpha, otherwise stock. I found the source of my Wi-Fi disconnect problems: it was my Belkin WeMo switches! I unplugged them, and I haven't had a disconnect in over a week. I haven't experienced a single other problem with this setup. (knock wood)

Wifi constantly reconnecting at home

A few weeks back I've upgraded my OPO to Android M using a ROM from XDA. Since then, my phone will constantly connect and reconnect at my home wifi, but *only* at my home wifi. All other wifis work without any issues. I did not change anything at my Wifi Setup at home, so this has to be somehow related with Android M, also no other device at home is experiencing the same problems.
I've tried multiple different ROMs since then, even installing new Modem, Kernel and Firmware but the problem still persists and it's driving me mad because OPO will burn through its battery in no time constantly reconnecting..
Anyone got an idea on how to fix that?
I got the same issue. Can't find a solution

It would be better to ask in the thread related to the ROM you have installed.
