[Q] Wi-Fi doesn't work anymore - Nexus 4 Q&A, Help & Troubleshooting

Hi guys, I need you to help me with my N4 because as it is said in the title, the wireless connection has left working (since yesterday).
I'll put you in situation: Yesterday just after touching the icon to open the navigator (waze) the device showed an "interference" on the screen and turned off. It was difficult (at least 10 tries before working) to restart the phone, and that interference was again on the screen at the begining of the first seen of the deskboard(you know, the main screen with the widgets and all this kind of things). When I came home 4h after this strange happening I realize that the Wi-Fi didn't work.
This morning I've been trying some things like shutting down the device for around and hour and try again, disabling the NFC or restoring the default settings but no one of these tries has worked so... I'm worried.
The device runs Android 4.2.2, never has been rooted or flashed or something like that.
Can you help me with this trouble?

You can't connect to a wifi network or you can't activate the wifi module?

I can't activate the module. Anyway, I've been speaking with Google's support and it is possible that it has been caused by an short-circuit on the mainboard so they're going to change the device for a new one (thanks to the warranty).
Thank you very much for your interest.

Help - Bluetooth and wifi keep turning themselves on

Hi, guys. Hope you can help...
We have two xda execs on o2. The first is fine - no real probs. On the second, wifi and bluetooth keep activating themselves and are a drain on the battery.
I can't seem to turn it off - The turn on wifi and bluetooth boxes are checked in settings even though I unchecked them half an hour ago when I last turned off bluetooth and wi-fi.
Am I missing something obvious?
Thanks
I would gladly swap for my XDA which keeps switching Bluetooth OFF! lol.
Sorry, I couldn't help from posting given that a significant number of XDA users have the complete opposite problem..
Other than that, I can't help you. I assume you're not running any third party software on there to monitor BT / WiFi ?
Not sure which is worse!
I'm not running any monitoring software.
gaspx: didn't you resolve it yet!?

@Vijay, nearly! -- I think ozBT is going to be the saviour for my XDA, but today it was my BT headset which had stopped working(!!);
Actually, come to think of it, ozBT will also switch off BT / Wifi, so you could do worse than downloading that Goldie..
http://oz.sciox.org/ozbt.html
Although i'd be more inclined to look at what software you have installed on your Exec and try and find out which, if any, has BT/WiFi hooks that may be turning them on automagically.
Failing that, Hard Reset the whole thing (after a backup is taken of course..) and see whether the problem is still happening on a fresh device.

O2 Xda Stealth, Wifi card not detected.

Hi guys,
Inherited a Stealth few weeks back but i realised that the Wireless option (to turn it on and off) doesnt work, nothing happens when i try to turn on my wifi, so i did a hard reset, but after the hard reset, it doesnt even detect or show up my wireless options. Any ideas guys?
What ROM are you using ??? I had a similar problem with my stealth for over 6 months after upgrading ROM....I tried every thing including careful changes in registry ....the problem was only solved after downgrading to the original ROM more than once ....I still get minor problems when WIFI wouldnot load but works after repeated soft reset ....I suggest you try to soft reset few times an see if this solves the problem....best of lucks....
hi man,
Thanks for replying.
I am using WWE_RM061208. Everytime i restart the phone it says, "Unrecognized card in slot" i am assuming this is the wifi card? any ideas? which version rom should i be using? It asks me to enter the device driver/name or something. thanks.
The unknown card is the wifi card....I used to get this notification daily for over 6 months when the wifi was not working .....Try soft-reset few times and if the notification disappears then wifi should work.....Is your ROM Original or cooked???? have you upgraded the ROM at all??
HI man,
Yes i have upgraded the ROM from www.mwg.com but it doesnt really do much, some of the settings still are around. Any suggestion which ROM should i use? What ROM are u using man? I tried soft reseting a few times but it doesnt work, it still comes up.
The ROM from mwg is original and I used it for downgrade from wm6 (YUC)..... is the wifi working when you hard reset the device ????....I used yuc wm6 but because of wifi problem there, I downgraded from mwg and then upgraded again to yuc wm6 from here

Hello All,
Since a fortnight, am observing strange problems within Network (clogs) and Virus Attacks on my Internet Cable based connection. This is a 256 Kbps line.
Problem I can see is:
a) A script or attacked is launched from a remote server/machine. It's domain address is 222360.com. Attacks happened from union.222360.com, s.222360.com and now with v.222360.com.
b) Once the scripts is launched (.js script), it gets hooked within my browser (Firefox 2.0.0.11).
c) Then, my internet activity will be disrupted severely for some time!! (can't open any page). I am using "Adblock Plus" within Firebox to block this script off.
d) Is there is no script, an attacked is launched on the open HTTP ports or on Yahoo Messenger.
e) Ultimately, an attack is made in form or Trojan or Exploit to gain access or to steal information from my system.
I can see the following logs from the NAV 2007 firewall.
I have similar problems with my stealth..
But worse...
My wireless manager only shows Bluetooth and Phone..
No more Wi-Fi thing..

I had a similar problem with wifi for over one year . I had to down and upgrade my stealth 3 or 4 times and finally worked alone after repeat soft reset ...another problem is that you may see wifi icon but doesnot work on pressing it...try removing the battery for 6 to 12 hours and restart again...now at this time I did soft reset for my stealth and the wifi didnot load but iam sure it will work after few hours or tomorrow
First of all thank God,because sending this guy(Yuc) to us..you gave a new life for our O2Xda Stealth,like a candle shining in the dark..Trilions thanks to you.
Actually i would like to ask somebody's help about ZiIME.CAB.. i deleted phoneime.dll but still can't delete zisip_Opt.dll.. it said "Cannot delete file ZiSip_Opt:the file may be in read-only memory,on a write-protected disk,or currently in use by another applications"
is there another way to delete this file?
Secondly how to kill "cprog.exe" in Task Manager?
Another silly question is can somebody upgrade O2XdaStealth GPRS Cellular Data Link to 3G or 3.5G..or is there any Booster for Internet connection?
the 02 xda stealth camera. it was its quality built-in GPS receiver, CK3300 adds navigation functions to the benefits of the CK3100 kit. It enables the driver to access wirelessely NMEA-0183 standard GPS data via Bluetooth . Those Data can be used with all Smartphones or PDAs. The GPS output may also be utilised with the Route 66 navigation software for Symbian mobile phones, allowing not just house-number precision navigation but also up-to-date traffic information.
After almost 9 years from this post, my stealth is still alive

[Q] Some apps can't connect using wifi (but can using 3G) on my Motorola Defy

Hello,
If you don't want the boring details of how I discovered the problem feel free to skip the next couple of paragraphs and go straight to the technical details.
I got my first Android phone (Motorola Defy) a couple of weeks ago and at first I was only using it with wifi because my data plan wasn't activated yet. While playing with it a little I realised that I saw a lot less ads than my boyfriend on his 6 month old Defy. I thougt it was weird but, well, seeing less ads is not a big problem.
Then when I got my data plan I saw that when I wasn't home I saw a lot more ads, so I began to suspect it had to do with how my phone was connected to the internet : wifi or 3G.
Next I wanted to try out Astrid and when I tried to log in using my Google account it failed repeatedly. Until I disabled wifi and it logged in fine using 3G.
Then I installed RTÉ DocOnOne to listen to documentaries while falling asleep. When wifi is enabled, it cannot start up because it can't connect (network timeout). Over 3G, no problem.
At first I thought it was my router blocking ports or something but it happens with different wifi APs and more importantly my boyfriend's phone, connected to the same access point, loads everything without a problem.
Let's sum up:
Some apps can't access the network using wifi but work fine when using 3G.
It happens regardless of the wifi AP (tried 4 different ones with different routers) and another phone using the same app connected to the same wifi AP can access the network just fine.
If I initiate the connection using 3G then switch to wifi (typically I launch the app with 3G, switch wifi on without closing the app), it still works after that (RTE DocOnOne has no pb streaming the documentaries once it has launched)
My phone is a Motorola Defy, French retail ROM, not rooted, no motoblur account (skipped the configuration), Froyo 2.2.2 (already on the phone when I got it), system version (if that means anything to you) Version.34.164.3.MB525.Retail.en.FR, kernel 2.6.32.9-g050ccf2, build 3.4.2-164
I can't give as much details about my boyfriend's phone (that doesn't have the problem) because he's not here right now but I can tell you that it is a Motorola Defy too, French retail (I think) ROM, Froyo updated from preinstalled Eclair (using the official Motorola update), not rooted, with a motoblur account
I have no idea if that's relevant or not, but my phone has the "google maps 5.7.0 crashes on Defy" issue (18446 in the android issue tracker) and my boyfriend's phone hasn't.
Has anyone encountered this issue before ? I couldn't find anything on this forum or with a google search.
Is there any tool I can use to try and find the cause of the problem ?
Thank you for reading all this, sorry if my message was long but I wanted to give as much detail as possible to help the nice people who may find what is wrong with my phone
I didn't read all..
but if your phone don't have problems then check this:
1. go to settings
2. Select "Location & security settings"
3. enable this "Use wireless networks" Location determined by WiFi and/or mobile networks
4. test does it work...
Hello manumanfred,
I did what you suggested (actually it was already checked) and the problem is still there (tried unchecking it too).
I am not sure why you suggested it, was that related to some phones having wifi problems in some countries ? I read a thread about that when I was researching my problem but it is different. In my case, wifi works most of the time, but some requests always time out.
Thanks for trying
Anyone else has an idea of something I could try ?

Hello, did you solve the issue?

Optimus 7 E900 WiFi is dead?

Hello, does anyone have an idea what's wrong with a E900 I have? It used to work just fine, and it still does, but it keeps deactivating WiFi. It also is not able to find _any_ WiFi network at all though it says it is searching. The rest works. Anything I can do apart from sending it to LG?
The phone is running 7.5, though I'm trying to update it to 7.8.
A hard reset didn't help. And as soon as I go back to the main settings page (from the place I can activate WiFi) it is turned off. So go in there, turn on, go back, off. Rinse and repeat.
Sounds like a defective part to me...
Bluetooth does work, and so does the FM radio. Aren't they all supposed to be in one chip?
I've had some problems with my E900 which only a double hard reset solved the problem, but nothing with the wifi. But always worth a try
I have a similar problem, after a certain update, wifi is buggy, and doesn't get a proper ip from my router. I'm positive it's a software problem. Any suggestions?

Wifi stays on but constantly disconnects from network.

Just as the title states, I'm having major issues with wifi. It's the phone, it's not the network or router because it works well with all of my other devices. I've tried resetting the router anyway, I've removed the network information in the phone and reentered it. The only thing I think that might have affected it without me knowing at the time was when I left the phone in my car and it overheated. I actually did that twice. If that is what caused the issue then I think I'm out of luck and it's likely not repairable. My first thought was the wifi antenna or something but because it does still connect I don't think that's it. Anyone else have this happen?
How you check your WiFi preferences?
By default WiFi disconnects after certain time...
Make sure is set to "NEVER"
Does it say "Connected, no Internet" and then disconnects and tries to connect again?
Is it switching to 4G because better signal? Turn off aggressive wifi handover in developer options if set. Check other settings too.
Turn off mobile data and see if behaviour is different as a quick test.

I can not find this setting, what menu is it under? I checked in Wi-Fi settings and Wi-Fi>Advanced. I've had the phone for some time now, this happened all of a sudden.

In the notification bar it would still show Wi-Fi signal status (on, with full bars) but it would go from displaying "network name" to simply displaying "Wi-Fi". If I long press it takes me to Wi-Fi setting and I can reconnect manually. If I turn wifi off and back on then it DOES NOT auto connect back to the network, despite the fact that the network is saved.

It happens when I have full Wi-Fi signal. Auto switching is apparently turned off, as mentioned above. When I turn off mobile data, it still disconnects from the network, leaving me with no data connection at all. Developer options were off, but I turned it on and checked but that option is off.

What Android are you using?
You could update to 7 / 8.0.0 US Beta or use a custom like me. Im currently on Android 9 Treble Pixel Experience and its working nice.

I'm running 7.1.1, B35. It would be nice if it was just a software issue, although I hate having to back everything up and wipe it. I haven't been keeping up with development, how reliable are A2017U flashes now? I think I remember them being risky with this phone when I first got it. Is any functionality lost? I would prefer to wait for the OTA 8.0 update since it seems to be coming but maybe...
I'm having this problem but mine says that the wifi manager has disabled wifi permanently. I can start it manually and it will connect to the internet for a few minutes then revert back to disabled. This happened after the 7.1.1 update.

ZTE Germany just released a message on their Facebook saying they're in their last stages of testing the Android 8.0 Oreo beta and will release it officially soon. This can be as long as one to three months away, or even longer.
If you're running stock, then flashing a custom rom will provide you with more functionality and performance. Battery life will definitely be shorter though, so say if you're getting 6-7 hours of Screen-on-Time on stock 7.1, you'll get around 4-5 on a custom rom. This entirely depends on your usage however. Flashing custom roms is quite easy and risk-free if you know what you're doing, and follow a good guide. Check Oki's guide on how to flash an 8.1 treble rom if you'd like. The current LineageOS 15 and 16 builds drain quite a lot of battery compared to other roms. If you'd like a good and stable Android 8.1 Rom, I'd recommend NFound's AEX 5.8. If you're like some of us (me included), you can live life on the cutting-edge and flash a Android 9 Pie rom. I wouldn't recommend it though as unless you know what you're doing with a GSI, DON'T flash one.
Always backup before attempting anything.

A few weeks ago my Axon 7 started doing the exact same thing that you describe. Were you able to find a solution?
Same for me, I'm having the exact same issue.
Did any one of you find the solution for it? :/
