I had CM11 on my Nexus 4 and did a full wipe, then flashed the official Lollipop image (using flash-all.sh script). The process went smooth, without any problems.
Now, I am having WiFi issues. When I turn on WiFi from quick settings it changes the icon, but doesn't connect to the network yet. If I try to access WiFi settings it opens them up, but I can see only the actionbar and a blank white screen. No networks shown. Sometimes I even get "The app is not responding dialog". It sits like this for about 30-60 seconds and after that it connects to the network and I am able to access WiFi settings.
Sometimes I can't turn WiFi on at all. Quick settings don't change the WiFi icon to the ON state. If I try to turn it on from the Settings, the switch does literally nothing - not even "Turning WiFi on..." shows up.
I tried to reflash the system - still get these issues. Tried reflashing just the radio module - didn't fix it. No idea what to do. KitKat worked just fine.
Does anyone else have similar problems?
Same issues, but on a Nexus 10.
I have exactly the same issues as you, but on a Nexus 10. Running LRX21P 5.0 Lollipop.
+1
I used Wugfresh 1.9.6
Downloaded and installed LRX21T
Did a complete wipe (cache and factory reset)
Did a selective restore of ~75 apps from Google backup
Played with the machine for hours.
Rebooted, now got no wifi
Anyone suggest a workaround?
EDIT: I came across this post in the Nexus 5 Thread , where he suggests changing your router's channel to something below 12. I changed mine from 13 to 8 and now wifi seems to be working.
EDIT2: Sadly the above was a red herring. The problem seems more complex. Hopefully Google will release a fix soon

I don't think my problem depends on the available WiFi networks. But thanks for the response.
I have the exact same issues, Wifi doesn't turn on at all. It doesn't matter if I press the quick settings button or the button in the menu. It says Wifi on, but nothing happens. After the screen goes dark, Wifi turned itself off again.
Any suggestions? Thank you!

I'm having the exact same issue. Wiped with ADB and flashed LRX21T factory image from Google's website. No error codes during flash.
Wifi is great - if you leave it on all the time. As soon as it turns off, it will NOT turn on. I get no error message, no timeout like it usually does when Wifi isn't working properly, no crash report. Nothing. Just a stalled Wifi acting like it's turning on. If I exit Wifi settings page, and come back, it shows as being off. Turn it on, and it just hangs the same way.
So frustrating.
It's for sure not the network I'm on, as it also doesn't turn on when I'm not near Wifi, or when I'm at a friend's house. Rebooting the phones makes the Wifi work again...until it turns off for ANY reason. Then we're back at square 1.
I'm having this same issue...
My WiFi seems to turn itself off. Then there is no way I can get it to turn back on unless I reboot the phone.
Very frustrating.
I have the same issue.I sideloaded the OTA and everything went great,no errors during the installation.I was on stock 4.4.4.
When I turn on the Wifi it takes around 30 sec to connect to a network.If i click on the Wifi menu in the setting it usually freezes or I get a black screen.After that Wifi works fine,but another thing I noticed it doesn't remember new networks.I don't know if a factory reset would help...
Anyone find a solution yet? Did a factory reset eliminate the problem for somebody?
I got the same thing. Currently, I'm using Power Toggles to do the on/off setting.

Are you saying that Power Toggles fix the problem?
I'm facing a different issue. Whether I have WiFi on or off, it always appears active in the battery usage stats ('scanning always available' is off)
WiFi was off when the screen was off from about 3 am to 2 pm.

I am having the same issue. very frustrating. it was working perfectly last night on my home network, but now it wont connect to my work network. it has the same issues as everyone else. the wifi toggle will turn on, but it will not show any networks. then after a couple of seconds it will turn itself off.
^^i am having that issue as well. the battery usage stat page is showing wifi as on even though it is off.
Have the same issue. After some standby time, turning Wifi on again, it showed me networks where I am not close to anymore and didn't show me the actual networks where I am right now. This seems to be a serious bug that needs fixing. I don't want to reboot my phone to fix it. Didn't Google delayed the Lollipop-Update because of some Wifi issues?
I have all the symptoms listed in this thread. I filed a bug report too: https://code.google.com/p/android/issues/detail?id=80028&q=LRX21T
Found this thread when this problem popped up for me after flashing the factory images one by one. Might try to find a source-built ROM using a later version to see if it got fixed.

I have a stock unrooted Verizon Galaxy S5. For several months my phone has been plagued by several issues at startup. Whether I reboot the phone or start it up after the battery has died, it always enters an odd state immediately after loading and seems to get stuck in this state for an undetermined and variable amount of time (anywhere from a few seconds or minutes to hours or even overnight).
While in this state, this is what happens:
1. Screen stays on. Once I unlock the phone, the screen stays on. The side button doesn't do anything to lock the phone or turn off the screen. Holding down the button, however, still triggers the power menu. The screen timeout never triggers, even though it should turn off the screen after 2 minutes of inactivity.
2. WiFi and Bluetooth turned off. Even if they were turned on before I powered down the phone, they are not enabled when the phone first boots up. I can manually turn them on but the WiFi will not connect to a network, even if one is available. It may show it is connecting to the network, but it gets stuck at "Checking the quality of your internet connection" and continues to use the 4G network for data connectivity. This happens no matter what WiFi network I am within range of, so it's not an issue with the network or router itself. If I am not near a network at all I will still experience the other problems of not being able to lock the phone, etc.
3. Startup applications don't load. I have Tasker on my phone, but it doesn't load and show it's notification bar icon.
Otherwise, I can use the phone normally and open applications, surf the web, etc. It seems that loading some applications and using the phone eventually causes the phone to exit this mode, but I haven't been able to find a single particular application or series of steps to fix the problem. If I power on the phone and don't use it that just seems to make it take even longer to fix itself.
Once it gets out of it's weird state, the WiFi connection will become active (it will turn on WiFi if I haven't done so manually already) and it will connect to a known network if one is available, the phone will lock itself or I can do so from the side button, and things like Tasker and Power Save mode will turn on.
I am stumped as to what could be causing this problem or how to fix it. It seems the phone may be doing some kind of check, maybe related to Knox, that hangs during startup and prevents certain things from working until it straightens itself out.
Any clues into what this problem is, what is causing it or how I could further analyze this problem and determine its cause would be greatly appreciated.
Never heard of or experienced these issues. May want to contact Samsung.
Have you installed any official updates from Verizon at any point? I've heard of phones having phantom problems like this after receiving a bad update. I would definitely contact Verizon if you did update at any point. If not then like BigBot96 said, contact Samsung about the problem.
My wife's Note 2 did something similar when the battery died. I had to factory reset. Her phone was rooted/unlocked & running a custom TW ROM, though. May I suggest doing a complete factory reset and Odin. Backup data to computer or external sdcard since this will clear the entire device.
Edit: After rereading OP's post it actually sounds like an app is hanging at startup which could cause this behavior. A logcat should tell you what's going on.

when turning my wifi off it seems it goes into some weird loop of turning on and off constantly by itself, it doesn't seem to be trying to connect just flipping the wifi switch on and off none stop.
noticed it because i had a huge battery daring overnight and while trying to fix it i saw the switch going off and on all the time.
when turning it back on it seems to connect normally .
did a network setting rest but it did nothing ...
I'm guessing a factory rest will fix the problem but I'm hoping to avoid such a overkill solution :crying:
does anyone else had this problem and can help me fix it?
thanx!

original samsung rom.
just happened (i have the device for a a while everything was fine) its the android system that drains the battery in the battery status.
when i leave the wifi on it stops and works fine ...
Have you turned off ''Keep Wifi During Sleep''? I know this can drain battery.
It's not so easy to troubleshoot on an orginal none rooted phone.
You can try clearing dalvik and cache.
Turn it off and then on holding power and vol down button, then clear cach/dalvik and restart.
Try uninstall update beaming service for samsung then restart
If still persistent try uninstall update microsoft onedrive and skype then restart, just in case
I found it after factory reset (forgot internal data backup :crying and update all apps, this problem occuring after the last 3 updates (beaming, onedrive, & skype) which more suspect beaming service update make that problem
Your not alone
You're not the only one who suffer from this exact problem, on Friday or Saturday the same problem started occurring with my phone too, WiFi turns on and off in a loop and huge battery drain!
I saw an increase of 6% of battery drain per hour, so I ended up on 9% total drain every hour. :crying:
I have original Samsung Rom and phone worked prefect until now, no settings or apps installed before this happened either.
What rom version are you guys on?
I'm having the same issue. However, I'm on PhoenixX Rom. Major battery killer and has only just started happening within the past few days.
Since my phone has been unplugged, 3 hours ago, looking at BetterBatteryStats, It is showing com.google.android.gms as having quite a LOT of wakeups. 40 per hour (everything else is about 2). Don't know if this is normal as I don't remember it before the Wifi issue.
Looking into what the wake ups are caused from, Location and heartbeat were the major culprits. So i have turned of WIFI scanning when not on and also the body sensors for Google Play. We shall see.

Easy fix. Just disable Wi-Fi scanning.

its not a fix at all . it dosnt scan for wifi , just turning it on and off non stop.
like pressing the light switch agin and agin
I had this after installing "GoodLock" software from Samsung! Uninstalled and everything is ok
same here, just noticed I wasnt on Wifi and the switch is just flicking on and off by itself. Standard S7 with all the updates installed
Been struggling with the same for some days (4 - 5) I haven't been able to get exactly whats triggering this. I'm on stock rom with root. I've reinstalled firmware clean again and re downloaded my apps but it is still happening randomly. Some times after a few attempts to switch wifi on (even when it is toggling by itself) it manages to keep on. Sometimes restarting makes it work again. One thing I'm almost certain its that this usually happens after I turn wifi OFF and then try to turn it back on.
It's been crazy and the phone starts to overheat after a while off this on-off loop.
Any ideas?
its very wierd it started to all of us in the past few days-weeks . seems like samsung has a bug they need to hurry up and fix.
AT&T just pushed out the October Security update for the S7 family, I'm guessing something that came along with it is creating the problem.
mine did a software update last week and I've been away in airplane mode so it could have started then. I've just disabled scanning and that seems to have got round the issue and I'm now connected to WifI
I'm not sure whether it is a Samsung Issue or a Third party one... It is true that something recently affected all of us, but as far as I know, it could be a third party app that wasn't well developed for our phone.
I've noticed the same problem on my phone and it's also only started up in the last few days. On stock Sammy rom, unrooted. Will be monitoring this thread to see if the experts here can narrow down the culprit.
I had the same issue and I was able to stop the toggle by turning off the wifi scanning in Location - Improve Accuracy - WiFi scanning. It's a fix for now. I think it may be an app that may have been updates that is persistently looking for location updates.
Anybody else having problems with the YotaEnergy application? The screen that notifies me that YotaEnergy has been turned on (YotaEnergy mode extends your battery, etc, etc...) keeps showing up constantly every few minutes while I'm in the process of using the actual e-ink screen, which is no end of annoying. Furthermore, I can't disable YotaEnergy altogether, because it cannot be turned off when my battery is below 50%, ignoring all of my settings telling it not to turn on at all.
Is this a defect in my phone? Can I get rid of the horrible thing altogether?
In case anybody has an ideas, I've now updated to the latest OTA CN update, and the situation seems to be that the YotaEnergy settings are completely locked. Any changes I make are immediately forgotten, and it's permanently turned on. If anyone has any ideas, I'm kind of desperate. I'm on vacation and am hesitant about bricking it in my attempts to fix it. Does anyone know if it sets settings on a plain text settings file? Maybe I can manually change it that way?
Hey guys,
This problem has been going on for a week or two now. Phone worked great when I first got it, but something must have changed (newest Verizon update, perhaps?)
Let me preface this by saying I've seen this happen both on Wi-fi and 4G. When on Wi-fi, and it happens, I've tried turning Wi-fi off and still get the same errors.
The apps affected seem to be random. A couple days ago it was Google Maps, I was getting the "offline navigation" prompt. Today it was Chase (couldn't screenshot it), TeamViewer, IMDb and so on.
Here are some screenshots. Note the time in the pictures.
- First encountered the problem when opening TeamViewer.
- Did a Speedtest to confirm that yes, I'm really on 4G as the phone shows, and it's quite a stable and fast connection too.
- Let's try some more apps. Here's Target's Cartwheel
- Delta app? Same problem.
- TeamViewer Host app. Same problem as the client.
- IMDb. One more random one not working.
- Lastly, I went back to Pokémon Go to confirm I DO still have network connectivity (not sure why the screenshot got ghosted like that, but you can see I just redeemed items from a Pokéstop I was near with no errors)
So as you can see, the phone itself, as well as certain apps, work fine. But others don't. I tried turning airplane mode on and back off, disabling/enabling mobile networks, nothing works. The only thing I can do is reboot the phone.
Any ideas? This gets incredibly annoying as I can't seem to go a whole day without *some* app whining that it has no network access. Some apps work flawlessly every time (like the aforementioned Pokémon Go) but others don't.
By the way, that little screenshot button in the bottom left is from this neat app called Custom Navigation Bar. I'm pretty sure that has nothing to do with this problem, though, all it does is add buttons.

Do you have powersave mode on? I've had some problems with it enabled..
No I don't have power save mode on. Should I turn off the power monitoring of apps as well? Didn't think that mattered as long as power save mode was off.

I turned all the power saving stuff off and still have this happening. As in, I set it to not even monitor how much power each app is using.
