Android 5 Lollipop Wifi Bug fix - Nexus 5 General

Hey guys I had this bug earlier today, here is how I fixed it. Fairly strait forward change your wifi channel to anything other than 12 or 13. Video below if you need it.:

I just saw your video but I think the problem im facing is that too many wakelocks thats draining my battery.
Also im an old follower to your youtube channel your work is great

Thanks m8, all my nexus devices are having wifi issue with anything above channel 11, really odd bug can cant get 5G working at all so no AC currently.
Such a strange little bug.

I'm having problems connecting to a Channel 11 WiFi that I don't have to its configuration. This happened since the L Developer Preview and is still there after the 5.0 release.
However, it worked perfectly fine on versions 4.4.4 and older!

A bug report is here.

Thanks, I was on the point of rolling back to 4.4.4 as I wasn't able to get wifi to work again, other than from Safe mode.
However it seems to be working now that I've shifted my channel from 13 to 8

I have the same problem here, finally i'm not the only one having this issue. Fixed after changing Wireless Channel number to 11 from 13 and i'm not sure if this is also related with Wifi drain bug.

Has no one tried:
settings put secure wifi_country_code UK
I'm not in the UK so I can't test but...

Has anyone tried the 5ghz channels? I'm testing on my Shield tablet and I can only see channels 36-44, whereas with Kitkat all the channels were accessible. I've started a thread here http://forum.xda-developers.com/shi...less-detection-lollipop-t2945899#post56965354

Can you explain where that code should be used? and what it will do?

You run the code in terminal or some other app that passes shell commands.

My wifi won't even turn on it just says turning on and doesn't actually turn on! Will changing the channels help that! I am not rooted!

I'm also facing a problem with wifi on my Nexus 5 (D821) with Android 5.0.
I can't connect to my wifi repeater TP-LINK TL-WA850RE, the device says it's connected but shows that "!" sign.
I don't know if it has something to do with wifi channels, since the repeater works fine on another devices running Android 4.4.4 and Windows, PCs, etc.
Don't know if it's another wifi bug on Lollipop or what.

Try just flashing the kk radio. This has worked for several people.

Not rooted ATM but that's one option I'm considering! Cheers

Am I the only one facing the following issue; in my battery stats, WiFi is shown as always on. Now, I turn my WiFi off when I leave for work and WiFi scanning always available has been turned off. Why does it still show my WiFi as on?

Nope, you are not the only one, I have the same problem. I actually did a clean install of Lollipop, it was terrible. Battery pretty much drained in about 8 hours with less than an hour of screen on time. I have reinstalled again (this time installed 4.4.4 and then doing an OTA). Lets see how that fares. Overnight, with minimal apps running I got from 97% to about 74% (7 hours) with wifi off, but in battery stats wifi is being shown as on.

Massive wifi bug on stock Lollipop

I have a variant of this, I've tried with both the .03 and .04 radios, it's the same, so it's not the radio itself:
I lose coverage so I get the wifi icon with the exclamation mark, instead of it reconnecting automatically. Switching wifi off, then back on, allows me to use wifi again.
I'm using the NX5 AOSP ROM, 5.0R6 (LRX21T)
We all get different experiences, but it sounds like the root cause is likely the same.
Give as much information as you can (Android version, radio, which particular ROM, usage), otherwise it's impossible to understand what could be causing the issue.

Did you do a clean install or did you just install it over your 4.4?

once you click "flash all.bat" it formats and cleans everything, so I guess I clean flashed it.

I guess I'm just wondering if these are issues are due to not starting a clean slate. I typically try to do a clean wipe of the internal NAND whenever it's a major revision change (4.4 > 5.0).
But if the bugs are persistent for those of you who did a clean install...maybe it's better to hold off for now.
I did a clean flash all as well and have the same issue where WiFi is never turned off. Wtf google. Battery was awesome right before the update

Thanks for the info. I guess I'll hold for now.
as for me, usb tether always turns of itself when i wake/turn the screen on

wifi works fine
Mine would lose connectivity, meander about for 30 - 60 seconds, and reconnect. I set the WiFi antenna to 2.4Ghz (from Auto) and turned off "Scanning always available" (although I doubt the latter had anything to do with it) and it's been fine ever since. This was on a clean factory install -- no root, no OTA update; pure OEM Lollipop ROM.
Whenever i go to settings > Wifi settings the phone freezes for a couple of seconds and then it crashes. This happens like 70% of the time.
Anyone else having this ?
I dont have any wifi etc problems
Only thing i have noticed so far is the recent apps bug that shows up sometimes

Phone: Nexus 4
OS: rooted Lollipop LRX21T
Bootloader: unlocked
stock Recovery
Bluetooth tethering between nexus 4 and nexus 7 breaks every 30 mins or so.
You have to reboot to get it working again.
Decided to take the plunge. Installed lollipop. Am happy to say that I do not have this issue occuring to me though.
yup, wifi issues for me.
Notice it when I get home, my wifi will not connect and when I go to check the settings it has been turned off. So of course I try to turn it on but everything I try does not work, I am unable to get it to turn on. Only a reboot will get wifi working again.
Not happy at all about this. and a couple of other features. Now I'm wishing I never did the update. Google you have taken my expensive smart phone and turned it against me.

It could be a combination of your router and something they've changed in how Lollipop handles networking.

I have the same issue. On my Nexus 4, I just set it to 2.4 GHz only, as 5 GHz has never worked since 4.3. I can only connect if I hold the phone up to the router. On my Nexus 7 where 5GHz actually works well, I like the fact it prefers 5GHz.

[Q]Wifi keeps getting disconnected after upgrade to Android 5.0.2

Both my phone and my wife's phone encountered the same problem.
I therefore do not think it is an individual thing.
It never happened before until we upgraded the system to the latest lollipop.
Any suggestion how to fix this?
Cheers!

Do a reset (obviously), if that doesn't work, run a software repair on Sony PC Companion.

I had similar problem, my phone had a little problem with authentication and regular disconnecting from wifi. I tried many things like hard reset, software update, router software update etc. even I came back from Marshmallow to Lollipop for a while, but nothing helped me. The solution turned out to be channel in my router. I changed it to 3 after that to 13 - but my phone works only with default channels like 6 or 8. After change my wifi get back to life and now work perfectly. Try it in your case
Channel - This field determines which operating frequency will be used. It is not necessary to change the wireless channel unless you notice interference problems with another nearby access point.

Best answer I've got about this issue. My home router is on channel 6 and the Wifi is really stable. The two work routers that I have access are on Channel 3 and 11 T_T

WiFi stops working

I noticed that WiFi stops working on my new G4 pretty often. The WiFi icon is on, and the connection is "up", but the data transmission stops working. I see the top arrow blink (is that transmit?) but the bottom arrow doesn't come up anymore. Trying to do anything fails and times out.
To fix, turning the WiFi off and back on makes it all work again.
Anyone else experience this problem? I know @jonathan3579 reports the same issue.
I am connected to 5 Ghz using an Asus RT-N66 running Merlin firmware. I have no issues with any of my other devices.
Using the "Switch to mobile data" option helps a bit by falling back on LTE when the WiFi stops working.

I'm having the same issue at home. I could be watching a video and suddenly stops. I don't know if it has to do something with root. I noticed it starts happening yesterday. I never had this issue and I got this phone sine 5/27 when it was released. I'll do a factory reset.

I'm not rooted and mine has done it ever since I got it (and did a factory reset before setting it up). I doubt resetting yours will fix your problem.

Are you having this issue everywhere you go or just one specific place?
I had not noticed it at work, but I only got on the WiFi yesterday for a little bit. This morning it failed on me, so, that's two for two. Haven't used it in many places.
The hotspot works great though. I tether an iPod Touch in my car automatically whenever I drive and I haven't noticed any issues there.

I'm at work and I have been watching multiples videos and no issue at all.
I just noticed this today happening to me too. =(.
Pretty great phone otherwise! Also connected 5ghz to a RT-AC68U (the T-Mobile cellspot), flashed with an older Merlin firmware.
Had to reboot to get it to behave again.
Me too
I've been having this issue too. I've noticed that I lose data and WiFi calling simultaneously. I thought it was my router because we were having issues with the router dropping phones and laptop, but now with a new router it is only my phone that is having a problem.

Running DNSet has definitely helped with keeping the data flowing, and I appreciate that.
WiFi calling is still dropping. When I look in the settings it says "enabling" and just hangs.
What internet provider do you have I'm assuming Comcast

This issue appears to be due to the 5ghz radio. I am not sure if it is software or hardware, but if you connect to the 2.4ghz band, the issue will go away.
Its most likely a issue with lollipop

Lollipop on the G4 maybe, but I have used a Nexus 6, a Moto X and a Dell Venue 7840, all running Lollipop, without issues. The G4 is the only one that has this issue. I never tested my old G3 on this network with Lollipop, I sold it before the update rolled out.
Problem fixed?

I switched to 2.4 ghz and WiFi calling appears to be staying connected. My provider is Oceanic Time Warner and my router is T-Mobile cell spot.
Fingers crossed and thanks for all the help.
Did these wifi problems start after root?
Mine were happening before root, I think. I switched to T-Mobile cell spot router right before I rooted because my old router was regularly dropping connections, and I have been paying attention more since I rooted. I am also caring for 11 month old twins, so things are kind of a blur. What I am saying is I might not be the most reliable source. I can say that switching from 5ghz to 2.4ghz seems to have solved my WiFi issue.

Nexus 6 signal drops and goes back only after airplane mode or changing 2g/3g

I've noticed that when using Mobile data internet connection (I use 3g only because my card doesn't support LTE) goes lower or completely to the 0 level, everything seems to work, but the notification just goes insane most likely. After I turn airplane mode for a while and disable it immediately it catches more signal as it should do all the time. It happens even on the latest 6.0.1 radio. Anyone had this issue out should I consider it as a hardware issue. Would be glad if someone gave me some feedback.
I also have the same bug with 6.0.1, it is a software bug not a hardware issue.

Yeah but my issue is a bit diffrent because I can acces internet with no problems, only the icon seems strange. There are no exclamation marks also.

WiFi disconnects constantly

It happens mostly when the screen is off (even though I have the always on setting enabled) but also when using the phone normaly. Suddenly I get a toast that I was connected to my WiFi. I've also checked the router logs an I see that the honor 5c is constantly disconnecting and reconnecting. Does anybody else have this problem? I'm on latest emui 4.1.2 without root or any other mod. I played with different channels and frequencies but that didn't help at all. Any ideas? I think it has to do with the battery optimization settings of marshmallow but even on the performance setting the WiFi connectivity just drops.
Whoever finds this will be my hero
In the wifi settings, just check that, "Keep Wi-Fi on during sleep" is set to always or not. If not then set it to always.
Edit : Sry i haven't read ur post properly. Is this the problem from the starting? Coz i don't have this issue.
I think I noticed this problem since the beginning but after flashing the latest 4.1.2 it got worse. Skype and WhatsApp calls get disconnected while screen is off (after 15 seconds or so).

Hello,
I have exactly the same issue. I checked also dhcp mode in the developer tools.
Did you found a way to solve it ?
Changing the router solved the problem.
