[Q] Mobile network stopped working - Nexus 4 Q&A, Help & Troubleshooting

As mentioned in the title, the phone can no longer find a mobile network to connect to. It says "Error while searching for network", when I try to manually select a network.
It all started with 3G and mobile data not working well together - the phone would rapidly disconnect itself from the current mobile network, and then reconnect after a few seconds. I "solved" that problem by disabling 3G.
Then, the phone started losing even the 2G signal, but I could get around that by manually searching for a network, and it worked like that for two days.
Now, the phone is refusing to connect to any mobile network, and I can not even search for one. Meanwhile, everything else, like WiFi, is still working.
I tried flashing factory images (4.4 and 4.3), as well as various radio images (none of them with LTE enabled), but nothing seems to work. Do you have any ideas?

I got same thing after upgrade to 4.4.1. Started over flashing from factory 4.2 and the phone upgraded automatically to 4.4, still no mobile data but wifi is fine. Everything is stock.

Wifi not working after Update

I followed the directions on the link below to update my phone instead of waiting for ota update.
http://www.mobilecrunch.com/2010/02...-android-ota-update-when-you-can-have-it-now/
Now my wifi won't work. It shows that it is connected, but it won't work with browser, sync or other apps.
I have never rooted phone, or flashed different radio.
I have tried removing ap connection and re-establishing several times with no luck. the 2g seems to work fine.
Any suggestions? Anyone else having this problem?
yeah there seems to be a issue with the new radio. My GPS stopped working after the update.
my wifi disconnects quite a bit more. i have better reception with the phone, poorer reception with wifi
FWIW, mine actually stopped working before the update, and still doesn't work afterwards.
+1 on the wifi issues post update. My n1 is freaking out on the select a network page - you click the network you want to join and the whole page refreshes and says there are no networks available. a restart fixed this once, but it happened again a few hours later when trying to connect to another network.
i did not force the update - clean OTA push.

[Q] Network Error

Hi!
After Updating to OS 7.10.8107.79 and Firmware 2250.21.21201.401 (Internet Sharing Update) I constantly have problems with my Internet.
If I turn on WiFi and leave Mobile Data on, pages in IE take ages to load and after finishing they just stay white. People Hub will also take forever to load, and there will not be any new newsfeed.
As soon as I turn off either Wifi oder Mobile Data everything works just as expected. If there is no Wifi signal and Wifi and MobileData is on everything works also just fine.
Anyone else experiencing the same?
BTW: Yes I did try a hard Reset, and yes it did solve the problem, but as soon as i used Internet Sharing again, everything went back to as it was before, and I don't want to reset my device every time I use Internet Sharing

[Q] I9505 loses mobile internet connection when it connects to LTE/4G

I have had this phone since its release in April and everything worked fine until October.
My phone started to disconnect from my mobile networks internet connection. Upon closer inspection I noticed it happened the moment my phone switched from 3g to lte/4g.
After showing lte in my signal bar it disconnects and stays that way until I turn mobile data off/on again.
Using the "3g only" option fixes the disconnection problem.
I have been on the same ROM from August to October, changed/flashed nothing.
Tried hard reseting the phone, no change.
Tried flashing newer radios and custom roms, no change.
I am starting to think it's a hardware fault.
If somebody has any knowledge about this I would be grateful if he could share it with me

[Q] Nexus 4 with AOKP won't connect to Wifi, "WPS failed" error

My Nexus 4 isn't connecting to wifi. More specifically, if I am connected to a remembered network, my phone does not automatically reconnect when I leave the range then come back into it.
Now, there are 2 wifi networks in the apartment and I've tried both. I actually just "forgot network" on the last remembered network on my phone because I was trying to connect to the better one.
Since I've done that, I am unable to connect to wifi at all, because the only way for me to connect to wifi before was to restart my phone and have it automatically connect to the remembered network.
Now that I don't have a remembered network, I cannot connect to anything, and my Wifi page on my phone will not show any wifi networks available and it won't even give the option to turn on wifi or to refresh the list. I have to reboot my phone, making sure the wifi is off first (using the toggle on the dropdown notification menu), then I can at least refresh the empty list. When I refresh the list, it gives me an error, "WPA failed. Retry in a few minutes."
I need this fixed. I live in a basement apartment and my cell signal is usually unavailable while I'm home.
I was running the AOKP 4.3 milestone when I started having the problem, then went back to stock, put on a 4.4 nightly ROM, had the same problem, then went back to the same 4.3 milestone. Unfortunately, I didn't leave my phone on stock 4.4 long enough to see if the problem persisted there.
Is there anything I can do at this point before going through the process of bringing my phone back to stock again?
Thanks
Update: After restarting my phone some 20 or more times, I was eventually able to see the list of networks and put the password in for the new network. So I at least have wifi now because my phone automatically connects.
However, all the problems stated above are still the same. I lose connection and cannot automatically reconnect when I go out and back into range of the signal, and can only regain the connection when I restart my phone and it automatically connects to the one known network on reboot.
If there's any information or anyway to try to fix it, I'd love to know.
Thanks

WiFi Connectivity issues in Ad based networks

On days, I hav tried to connect to WIFI network of Moscow Metro Stations. I tried it before and everything works. But suddenly I started to have issues while connecting. I can't find out the reason. I tried to reset all, hardware format, restore with factory images nothing works. I contacted to support of the WIFI, they say that there's something in phone that switch to mobile data instead of wifi as for Accessing to wifi, it redirects to page where I need to view some adds. I looked at wifi preferernces and turned off Smart WiFi Switcher. I tried to turn mobile radio off, airplane mod nothing works. What to do to get WiFi work in this situations ?
