[Q] Lollipop WiFi issues - takes long time to turn on or not turning on at all - Nexus 4 Q&A, Help & Troubleshooting

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.

Bell JK4 - Wi-Fi Discussion

After upgrading to JK4 via Kies I've noticed some strange Wi-Fi behaviour. It seems to manifest at different times and for no apparent reason, so I'm starting a thread to see if a) anyone else has this issue and b) if so, how does it manifest for them.
First manifestation: after turning on Wi-Fi through Notifications the text switched to "On" but the Wi-Fi symbol did not turn green. Going into the Wireless and Network settings on the phone caused a temporary lockup, when it did let me in Wi-Fi was showing "Error". A reboot of the phone fixed it, temporarily.
Second manifestation: after turning on Wi-Fi through Notifications the text switched to "On" and the Wi-Fi symbol turned green, but it did not connect to my wireless network automatically like it should. Going into the Wireless and Network settings on the phone caused a temporary lockup, when it did let me in Wi-Fi was rapidly switching from a "Turning on" state to "Turning off". It did this about 10-15 times in a few seconds then went to "Error". Turning on and off the Wi-Fi again solved this issue.
Every time I solve this it seems to come back within a 24 hour period. I didn't have this problem (from what I can see) on JK3. I factory reset before and after flashing to JK4, and I flashed JH2 back just to be on the safe side beforehand.
Let the discussion begin!

I quickly tried out after reading your post, and I did confirm your first issue happening, but only when I turn my Wi-Fi on and off really quickly. Also my phone didn't lock up as you described either. Basically, I could only make that issue to surface once I turn off the Wi-Fi, and then turn it back on as soon as my phone reports it is disconnected. When I go into Wi-Fi settings, it does say "Error" there, but if I check the "Wi-Fi" there again, it connects automatically.
I almost never use Wi-Fi because I get 6GB of data, but I can see this becoming a very annoying issue if you have to use Wi-Fi frequently.
Edit: Actually, I ran into a different issue just now. I kept on playing around with my Wi-Fi, and confirmed this happening: Wi-Fi text turns to "ON" but the icon doesn't turn green. When I go into settings, it says "Turning Wi-Fi On.." or something similar and is stuck there. I wasn't able to turn on nor off the Wi-Fi. Reboot fixed issue...for now I guess.
I have also had this issue but I believe it has to do with trying to turn on wireless when your preferred network has a very weak signal. When I'm next to my router, I can turn wi-fi on and off rapidly with no issues. I have only had the issue in my room which has a much weaker signal.

i was having problems with my wifi today...i wasnt able to pickup any wifi signals and i couldnt manually turn the wifi on either...i got a few force closes on some apps and decided to reboot the phone, hopefully sovling the problem...instead i got stuck in the boot loop at the i9000m logo and now my internal sd card is done....hopefully i can return this pos at bell(im on rogers) and do a hup through rogers for the iphone4...at least thats a stable device.

I've never tested right beside the router, but my room is next to the room which has the router so I would think I'd have a fairly strong signal.
Interesting, though...

I tested my Wi-Fi pretty much right beside my router as well...like less than 3 feet away. My phone was reporting it was seeing an "excellent" signal.

I find my wifi on my phone to be pretty solid.
I have an occasional issue where it does not see my wifi router at work, but all I do is turn it off / on and off she does. Just happens with the work router. Never had an issue with my linksys at home.
I've experience this issue with JH2 and it was caused by a change to fast in the settings. Just give your phone some time to connect and get identified on the network before you turn it off ans don't torn it on right after you disconnect it and you should be fine.
Been having the same issues since upgrading to JK4. Wifi gets stuck in "enabling" state occasionally when it try to turn it on. Sometimes I have to go as far as restarting the phone to get it to work again. Not a huge deal but still a nuisance.
I have seen both of these situations occur once after applying JK3 from Odin. It was shortly after booting it up for the first time including the "ERROR" text. I attributed it to a one-time glitch and it has not come back since. When I am home I force WiFi on and leave it in that state until I leave the house for work the following day so I am not constantly messing with the settings.
I get a similar issue butt only when activating my mobile AP.

I've been having a similar issue with my wifi since upgrading to JK4. I've gotten the "error" message on enabling wifi, but as others have mentioned it may be because I'm re-enabling it too quickly after turning it off. However, in one instance yesterday I tried re-enabling it several times after turning it off via the control widget and was ultimately forced to reboot before it worked again. Also, this morning I found that after leaving home and coming to work, I was still only seeing the wifi hotspots near my apartment rather than the ones in my new location (one of which I have saved and automatically connect to). I had to reset the wifi to find the local hotspots. Other than these wifi issues, I'm really loving JK4 so I just hope they get sorted out.

Wifi issues?

After I got the touchwiz update and the second smaller one my wifi is messed up. It doesn't stay connected once the tablet is left alone for a couple hours. The signal strength color turns to white instead of blue when it does this. To remedy I have to turn the wifi on and off on the tab. Anyone else with this issue?
I am not seeing this issue. Have you tried a factory reset yet?
check to see if you have wifi set to never sleep (in advances settings). i had similar issues and setting it to never turn off worked for me. no battery drain issues with that setting either.

Thats bugging me too. Not always but from time to time I see "No internet connection" when the tablet is left alone. Before the updates I never had this. The other issue is wifi roaming. To get connected again I have to push power button, sometimes unlock screen, even sometimes it waits until the wifi settings screen. Dumb!
Ya I have it set to never turn off. I would hate to have to factory reset it and lose all my settings and Apps got a ton of stuff on this bad boy.

Apps are easily re-downloadable. If you're rooted then install Titanium Backup and back up all your apps with settings.
Do you have aan older router? I have the same problem (I have to turn wifi on/off if I leave the tab alone for 20+ min) but only at my office where my router is a bit older. At home with my brand new Linksys I have no issues.
My wifi is set to never sleep btw...

Problems with WiFi Connectivity Since the Last Update....

Guys,
I updated my tab a few days ago. Now the market looks different but unfortunately I'm facing another irritating problem which I have no clue how to solve.
Every time that I turn off the tab, and let it be idle for 10 minutes, when I turn it back on, the WiFi icon will show no bars - which translates into no internet connectivity. That happens while the WiFi button is still pressed (green in the pop-up menu). In order for the device to connect to the net I need to turn the WiFi OFF and than ON and it works.
I checked the WiFi sleep configuration and they are set to "never turn it off" I also rebooted the device but with no change.
Please let me know what to do... as this thing sometimes just drives me crazy.
Thanks.

Flash a custom rom bro. Otherwise you are stuck with Samsung's awesome bugs. If you don't want to flash a custom rom there isn't really much you can do about it considering you're not rooted. What did you update to? KMP???
I did the regular Samsung update -the latest one that was released a couple of says ago. The problem with rooting is losing the coverage I have for insuring the device... which I'm reluctant to do. I'm sure it has a solution somewhere...
Yes I confirm.
This "reconnect" issue is being discussed on many forums with no solutions yet. (except custom ROM)

Wi-fi is bricked

Ok, so my phone has this problem where it keeps turning on and off randomly, which I think is now known is an issue with some LG G2's and you know I hate it but I guesss I can live with it. Even though if any of you have a solution for that please tell me. But now one time when it turned off and then powered back on, the wifi stopped working. I don't mean my network, I mean the actual wifi on my phone. When I scroll down my notification bar, the wifi logo is grey but it's flashing, like it usually does when you turn it on, but it doesn't turn blue. When I got to the wifi section on my setting, the on and off switch is greyed out (but faintly blue, even though you can't touch it), and when I tap on the wifi section itself, it just says "wifi turning on.." HELP PLEASE

Android N wifi issue

Decided to install N a few days ago and test it out, everything was going fine but after returning home from work today my wifi will not reconnect. I've added the info for my wifi back in several times, the phone says the network info is saved, but it never connects or even appears in the list. Don't really feel like wiping again right now, so did anyone else run into this and manage to fix it? Any ideas? I've already tried all the usual stuff, but no luck.

Apologies if this is a silly response but is N official? I thought it was a beta? I'm assuming if that's the case then you'll get variable success with connectivity and functionality.
Do got have the most up to date vendor and is the kernel your using optimised correctly or should you expect issues!

Definitely not a bug. I have been using the preview since day one, and WiFi is working completely fine. Here's what you can try - wipe cache from recovery. And then if it still doesn't show up, you may try resetting your router settings.
I have faced such issue, but that would be subjected to all my devices connected to that specific router. Caused generally by lousy internet connectivity, or some router issues.
I had already tried doing both those things but the problem still persists. I guess I'll just have to try a factory reset or wait for the next update and see if it resolves itself.

The next update is near. In case you can't wait, factory/reset would be good option.
Went ahead and rolled back to MM and everything was working well, then I reinstalled N and wifi was again working without issue. I just returned home from an interview though and wifi will not detect my network again. SSID is still saved, but won't appear in the list or connect. Did a cache wipe from recovery, re-entered my wifi info, reset modem and router, but still no luck. So it appears to be something that I can replicate, and only with N. Here's hoping the next update fixes it.
I'm on the N beta preview 3, and my wifi will randomly stop working on my 6P. I have to switch it back each and every time. Also, when I return home, my 6P won't automatically reconnect to wifi like it did on MM. Definitely seems like a bug.
I am using the latest preview. Wi-Fi won't connect. It shows both the 2.4 and 5 ghz options as saved, but it won't use either one. Older version of Android connects fine to same router. I have a NetGear router.
same issue
Yes I would like to report having this issue as well on the 6P in N beta. I have a 5x on MM in one hand 6P on N beta in the other . 5x has connection fine 6P does not using 3 different routers.
Android N on 5x experiencing same issue. Any resolution?
I can report the same. Has anyone discovered a fix?

Mine works well however if you turn it off and then travel away from your router with wifi off; it will fail to reconnect upon returning to your home wifi and turning it back on. Do you ever turn your wifi off for an extended period of time?

WiFi Issue
Don't know if related. In my case, cannot turn on/off wifi. Even while of it shows the progress bar as if it was looking for networks. Have no wi-fi at this point and unenrolling from the beta isn't sending me the rollback to marshmallow. This on a Nexus 6P
Temporarily fix
I found a temporarily fix till the next update (hopefully) fixes it. Hop to advanced setting and click on wps button. Wait for 5-10 second then click cancel. Hop back to wifi list and you should find your SSID. Sometimes it won't connect even though it's saved and appears in the list. What you want to do is keep clicking on connect. This should help, atleast it does for me. Nexus 5X on Android N.
