Android 5 Lollipop Wifi Bug fix

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.

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.

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 didn't seem to have this problem at work, so I'll monitor it again today (I just got the phone 2 days ago).

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.

Wifi Calling Stuck at Enabling

Hi Guys,
The wifi calling feature on My T-mo Galaxy S6 is not working at all. Whenever I try to enable it, it gets stuck at enabling.
Toggling Wifi on/off or rebooting the phone has no effect.
Can anybody help?
BTW I am on G920TUVU2DOF8 build, rooted, TWRP recovery and UniKernel.
Thanks

I have the same problem, unless I'm at home on my cellspot. Connecting to anything else is a no go. Still 5.0.2 rooted with ping pong for now. Sucks to have a major perk like WiFi calling not working for a flagship phone. Anyone have any clue how to fix this?

So is there nobody who uses wifi calling or wifi calling is working great for you guys?
I can't believe that there are not many complaints around this issue. The T-mo signal in my house sucks and I was kind of hoping that I can use the wifi calling feature instead.

Mine seems to work fine.

Try calling your phone from another source and see if that congratulations you have used wifi calling message pops up.

Possible fix
So I know this is a dead thread, but I found a possible fix if the airplane mode doesn't work. I shut the phone down, pulled the battery out and hit the power key a bunch of times. Doing this without the battery seems counter-intuitive, but it discharges capacitors when you do it on laptops, so I thought I'd try it on my phone. Put the battery back in, started the phone and wifi calling worked again.

This actually works for me. I just installed an App called TalkaTone(FREE but requires registration) and called my T-Mobile number and let it ring for a few times then hung up. Wifi calling finished enabling and started working.

Still no solution
I've been using note 3 for 4 years and currebtly it has phronesis rom 7.0.
Last week, after i charged with my powerbank, suddenly wifi stopped working, stucked at 'enabling wifi'. I rebooted a few million times, cleaned unnecessary apps including the last ones, hard reset, reinstalled rom, shook it, dropped it to the floor, threw it to the wall, but didnt help at all. And i thought it's a got broken as it's already 4 year old phone.
A few days later, when my charge was at 3%, the back of of the phone, right next to the camera heated too much, despite i was doing nothing, i got panicked and remowed the battery.
10 min later, placed it again, booted the phone, and tadaa, wifi was working, the back side was keeping cool, phone was smoother and charge level was %35 or so.
Then i thought, wifi issue was not a hardware thing but instead it was related to wrong battery stats. When the charge level was again 2% i removed tge battery again, waited fir a few min and placed again. It was again %25 percent,( didnt last long though,) but wifi again was not working.
Moving from that point, i fully charged the phone, calibrated battery, removed replaced etc... but didnt work.
I deleted the file data/misc/wifi, it didnt work.
Afaik blutooth and wifi use a common chip and if wifi is failing cos of a hardware issue, blutooth is not supposed to work as well. Yet, my blutooth works fine. Just wifi.
I dont know how to fix it.

Try it
I have no S6 , but you can try the Wifi Calling tool .

WiFi Problems

I am running Global 10.2. I got the phone on Saturday and since then I am unable to get wifi working properly. It will work for maybe a few minutes and then cut off. I have tried two different routers.
I am unrooted. Is there anything I can do apart from returning the phone or waiting until I can unlock the bootloader? TIA

I am having the same problem as you with my Mi9 very anoying works fine with the Hotspot shared from my Samsung S9+ but not all apps work via the home routers tried on 2 routers same thing MIUI update server is not reachable I also find Netflix doesn't work via home wifi from the MI9 but both Netflix and MIUI update work from the samsung phone hotspot netflix works fine from my other Android phones I own on my wifi though
Hope the fix this soon its very anoying.

Same problem for me : Wifi sharing is not working for all apps. It works for Chrome and Dropbox on my pc, but it seems some apps are not working. Those works with regular wifi. For exemple, nodeJS is not working fine.
Is the Mi9 blocking some ports ?

I got this problem too
I solve with set the hotspot band to fixed, 1 or 2.
But I have to set this every time I switch on hotspot.

Same problem

hi guys i m using the mi 9t and i have the same problem on 10.3.11, have you solved it or do u have any ideas on what is causing this stupid issue ?

happen to my mi9t today and i think it's kinda related to the co-ex problem between modem & wifi (problem not fix even rebooting the phone and restart wifi)
u can try the following step: settings-->wireless &networks --> more-->reset wi-fi,mobile &bluetooth
it works weel for me

Question Redmi Note 11 Bluetooth interferes with Wifi

Redmi Note 11
For the past three months, I am facing this odd situation where as soon as I turn Bluetooth on, the wifi disconnects. I have tried everything that I learned from Google and even reset my phone twice, but no solution so far. I have tried 5GHz wifi but still the same issue. I cannot use Bluetooth headphones or connect my phone to the laptop or smart watch while connected to wifi. I bought this phone in February 2022. It worked fine for a month and then this problem started. Please help.

If you haven't physically damaged your smartphone, then my guess is that you are experiencing a software (driver) problem -- in that case you have 2 options:
report this issue to Xiaomi & wait for the next MIUI release,
install (after unlocking the bootloader) a custom ROM (replacing MIUI) -- you can choose whichever you like:

a custom rom won't fix it i guarantee it , its a hardware issue . ive had the same problem with various devices over the years , phones , tables and laptops . the wifi and bluetooth signals interfere with each other . try putting your wifi on 2.4ghz bands b / g and see if it helps

I tested your issue twice just now. Connected the phone to a 5Ghz Wi-Fi then turned on the Bluetooth, after that I it paired with a sound system. The Wi-Fi never disconnected during the process. Maybe you have too many wireless devices in your area. Do more tests in a different location. Try flashing a different version of MIUI global if the issue persists.

Surprisingly your suggested solution was spot on. I had two smartwatch apps on my phone (one for Haylou, and the other for the Mibro smartwatch). I uninstalled both, restarted my phone and turned on both bluetooth and wifi. No more disconnection issue. Now have to figure out which app is actually causing the problem. Before your reply, I posted my problem on many forums and searched google, but no effective solution till your reply. Thank you very much.

Thank you for your reply, brother. But how can you test my issue when you don't have the problem in the first place? Regardless of which network I am using (home, office, friend's house) and on which band I am (2.4 or 5.0 GHz), as soon as I turned on the Bluetooth, wifi disconnects. Swapon88's suggestion really worked. It was the smartwatch app.

I am also facing a similar issue. When I am connected to Wifi and Bluetooth simultaneously, wifi disconnects after a few minutes and no Access points shows up in the available networks section. Wifi reconnects when bluetooth is turned off.

Yup, that seems to be the case. Can confirm such 'issues' happened on my moto g3, moto g5 plus, rn8 too because of interfering frequencies that causes either Bluetooth or wifi to disconnect (shortly).
