Wifi/Settings Crash - Nexus 4 Q&A, Help & Troubleshooting

Recently Flashed Semaphore Kernel 1.7.1 on my N4 running October 7 Carbon Nightly and everything was working fine until it disconnected from the WiFi and wouldn't reconnect. I attempted to reconnect by going into Settings and settings wouldn't open until showing a message about settings stopped working. Rebooting the device solves the issue until it disconnects again.
Steps I tried to fix it:
I factory reset and flashed the latest nightly and gApps then reflashed the HellsCore kernel.
Everything worked great until this evening the same issue occurred again, I could not access the WiFi settings after it disconnects from the Wifi even after rebooting this time it still wouldn't connect, a dirty flash of the ROM on stock kernel allows the phone to connect to wifi.
Help?

[Q] Changed Kernel and wifi won't connect anymore

So I tried to search, but was flooded with the incremental mac address issue instead.
I was using PRJ's desire build and then flashed over to MDJ. Rebooted, and the wifi just wouldn't connect. Wifi works and scans, but won't connect.
I task 29'd. I cleared the SD android folders and reinstalled magdlr. Same thing is happening.
Any solutions? It's driving me mad. I'm on the latest tmous radio.
So you didnt just change kernel you actually changed rom?
If you are having issue with a specific rom you should post in the rom thread or search for the issue in that thread.
I had a wifi issue with MDJ 1.9, I rebooted a couple of times, started and stopped wifi and it fixed itself.
No, I first flashed prj's rom. Then I changed the kernel to MDJ. Wifi stopped working so I figured flashing prj's all over again to restore prj's kernel would work. Nada.

[Q] Wifi won´t activate on stock 4.2.2/cm 10.1

Hi Guys,
I have a problem with my nexus 4. I wanted to use cyanogenmod instead of the stock rom, so i rooted my device yesterday and flashed the latest stable build of cm (10.1.2).
Everything worked fine, except for the wifi; it won´t turn on. It get´s stuck on the "turning on wifi"-page, wtih the button in off-position and saying "turning on wifi".
I´ve read some threads were people had the same problem, but nothing seems to fix it. I made a factory reset, wiped cache and dalvik, fixed permissions, but in didn´t work on cm 10.1.2.
So i tried a different build, cm 10.1.1 stable, but the problem persisted. I tried the same things I did on the 10.1.2, but it did not help. So I tried using the latest nightly, but that didn´t help either.
I thought i go back to the stock build to fix it, because it still worked after I rooted the device and still had the stock on it, but unfortunately that did not fix it. I made a factory reset, and wiped cache and dalvik again, but it just won´t work.
Long story short, i don´t know what to do now I rooted and flashed several devices before and never had a problem that did persist even nafter i tried multiple buidls of cm and wiping everything everytime; so if anybody has any idea where this problem comes from and how i could fix it that would be really great

Im having a similar problem, i think we have to flash a different radio ?
Still nothing
Flash a different radio? What excactly does that mean? I must admit I have not heard of that :laugh:
By the way, I just unrooted my device and relocked the bootloader, but that didn´t fix the problem either.
Stock CM Kernel? If so, try flashing kernels with prima drivers. If the problem persists, I guess it may be hardware. On another note, do you have bluetooth or GPS on? Try turning those off and try connecting.

I just tried the franco R163 with prima drivers, that did not fix it. But, speaking of the bluetooth, i´ve just noticed that the same problems occurrs with that. I trie to turn it on an it stays at "turning on bluetooth" without actually turning on. Maybe that helps to know what the problem is.
What other kernel with prima drivers would you recommend?
Edit:
I´ve read through a few threads on that bluetooth-issue, which apparently is more common than my wifi issue. I was wondering if my wifi-issue could have something to do with the bluetooth, because other users who have said bluetooth issue found their bluetooth temporarily on after reboot; then after a while the bluethooth issue appeared again.
In my case the bluetooth doesn´t appear to be on, but i was thinking that maybe it is, but the software fails to display that and that that is interfering with my wifi.
Could that be a possibility?
Out of the box my nexus 4 refused to connect to my TPLINK wr941ND router, wifi was set months ago, nexus 7 works as charm same with evo 3d and others. I thought wtf and turned on wifi on broadband modem, it showed up on nexus 4.... And suddenly network from router poped up as well. I switched off wifi on modem and nexus lost wifi from router. At this moment I went for a walk... When I come back done factory reset, reboot the router, no effect. Changed settings from WPA2/QSS to WPA without QSS - no change, then I changed channel from #13 (best in my location, all my neighbours using #1 and #6) to #1 and instantly nexus found network.... So it seems that sumthing is apparently with wifi, when I changed channel back to #13 it drops the connection and says that networtk is out of range. So finally I checked all the channels from 1st to 13th and it works from #1 to #10, 11 till 13 dunt work. Maybe this info will help sumone with simillar problems.

Try to do a complete factory reset and a clean installation of cyano rom... Maybe will fix the problem
Mahdi-ROM

Just reflash the ROM? And update your kernel man.

I dont think that the problem was the rom... Maybe the kernel... In this case you can try the lastest franco kernel :good:
If the problem reappear I will flash the Franco kernel
Well with Franco kernel Wi-Fi doesn't open at all...

Internet not working through wifi or 3G/4G

Last night my phone started acting up on the recently flashed official CM13 nightly 25-3. So I tried to restore my nandroid backup of the CM12.1 version but got stuck in a bootloop. I manually reflashed CM13 but can't get internet through wifi or cellular data, wifi is off and keeps displaying "Turning on wifi" with a grayed out toggle in the on position, Data is on but there is no H or LTE displayed next to my signal. Calling and texting work fine though.
I tried going back to stock Cyanogen OS with the windows toolkit but still the same issue. Installed Chroma kernel and flashed the Marshmellow firmware but still no fix.
Anyone have any ideas how to resolve this?
Edit: Data works now, it was an APN issue. Still no wifi though. And apparently Bluetooth isn't working either

Wi-Fi not connecting

Yesterday my Wi-Fi broke; it doesn't connect anymore. It sees the connection, and saves it, but doesn't connect. This happened on the latest version of RR for the vs995. It worked fine on RR for several hours but then I turned it off and it would not connect again. I tried a clean flash of RR, tried restoring my backup of Weta, and tried a clean flash of Weta. Nothing works.
I'm hoping there is a fix for this without having to return to stock. Thanks for any help.
