I have same issue, but in addition many a time, when I switch on Bluetooth, the WiFi connection drops.

There is in fact an issue with wifi on the Nexus 4.  I've written it up here:

http://things-linux.blogspot.com/2013/01/do-not-write-on-board.html

Thanks... but that is not the same issue...  I can leave wifi on all the time and it will never drop connection.  Even when screen blanks out.  The wifi will only drop when I turn on bluetooth.

The issue with bluetooth killing wifi is a known Android 4.2.1 issue.  Whether or not it is related to other wifi issues has yet to be determined, since the cause of the wifi bug has not been made public.  I have also seen the bluetooth killing wifi bug on My Nexus 4, all I have to do is turn on my paired Plantronics headset.

And for clarity, my wifi doesn't "drop" either.  But after the screen has been blanked for about a minute, it stops communicating.  A simple ping test to your N4 can verify this.  If you turn the screen back on you still see the wifi icon, but it will be greyed out. After a few seconds with the screen on, it will turn blue again (and ping will again reach your device).

Yeah, I had a discussion with a level 2 Google Play support rep.  They said they are aware of the issue and to please be patient for an update.  I think we need to make this more publicly known so that they get on top of it...

My wifi icon is always blue (when bluetooth isn't on, that is)... even after the screen's been off for quite some time and then turn back on.  Still blue...

Thanks for the update.  How did you get to discuss this with a level 2 rep?  Did you call Google Device support and escalate?

After a long discussion of "It must be your router..." or "It must be your bluetooth device..." or "you must have installed some app that's causing that..." or "those radios have nothing to do with each other..."  I proved to the first rep that my router + bluetooth device doesn't have any problems on my Nexus 7.  Then explained that I can get the same results on both Nexus 4 (dropped wifi) and Nexus 7 (perfectly working wifi) at multiple router locations - not just mine.  I then proceeded to uninstall every downloadable app... still the same problem...  I then reset my phone to factory settings... still the same problem... then I booted my phone in safe mode... still the same problem.  She was stumped... it was clearly a Nexus 4 issue as no outside force was causing this issue.

It took all that running around to present my case to a level two.  And of course... level two knew about it and said be patient...

Figures.  I've done essentially the same thing trying to track down the wifi sleeping problem.  I've RMA'd two Nexus 4's, and the third one has the identical problem as the other two. It's about time for me to call them back again.

Level one said I could do a warranty replacement, but if they don't find my issue, they would charge me full price for the new Nexus.  Didn't want to risk it...  Just send the update!!!

Interesting!  The reps gave me no problems whatever when I described the problem, said they'd RMA the phone each of the two times I called and described the problem.  In a subsequent follow-up email one of the reps said they'd never heard of the problem, so I sent them my write up (above) as well as this link:  http://code.google.com/p/android/issues/detail?id=40065

I told them they could read all about it there.

I've got this same problem on both of my Nexus 4s and one Nexus 7.

I've experienced the bluetooth bug on my Nexus 4, as well as several problems with WiFi.  However, I thought I'd share a few positives about the phone:  http://things-linux.blogspot.com/2013/01/the-good.html

I just posted about this in issue # 40065 (Comment 422 and 445) and that has been assigned an owner.
hopefully a fix is being cooked and its here soon.

I usually take calls via bluetooth and it is posing a challenge now with constant skips when the WIFI is on. :(

An estimate of when Google will have a fix ready for the N4: http://things-linux.blogspot.com/2013/01/count-down.html

I experience the exact same issue and I have submitted my bug report on Nexus 4 help page.

I am having the same issue. Was given an rma number but told I will receive a refurbished device and if there was no problem found with the phone, I will be charged...


I will be filing a complaint with the BBB. Putting a consumer in this type of position is completely unacceptable.

@16, agree this is unacceptable, especially since Google has finally acknowledged that Android 4.2.1 is the source of the wifi and bluetooth problems, not the Nexus 4 hardware.  See this blog post for details:  http://things-linux.blogspot.com/2013/02/the-natives-are-getting-restless.html

Once there click on the code forum link to see all the feedback there, or you can go directly to the Google developer post acknowledging specific problems: http://code.google.com/p/android/issues/detail?id=40065#c803

I have the exact same issue, wife works until I connect a Bluetooth headset then the WiFi will constantly drop and reconnect.  Making it impossible to use the Bluetooth headset over a WiFi connection.

I got N4 two days ago and found the same issue which makes it impossible to use skype with a bluetooth headset. Looks like it's been a while. Wondering how long they still need to fix this annoying problem... Or maybe I should just think about return the device?

+1 from me. As soon a phone calk starts over Bluetooth the WiFi connection dies. If I do a VoIP call over WiFi with a BT headset, the call will die because the WiFi connection dies. This is unacceptable for a flagship phone in 2013.

I am seeing something similar as well. Leaving Bluetooth off solves the problem, but isn't exactly an ideal workaround.

Got the same issue. :-(

Same here as well.  

individually they work fine, but it is impossible to use both wifi and bluetooth together.

Just updates my nexus 4 to android 4.2.2 and the problem is still there. Every time you use a Bluetooth headset when WiFi is on, WiFi connection will die.

Exactly same issue. I only found it when I tried to do VOIP using a bluetooth headset and the call won't go through since the WiFi will drop.

I got the latest 4.2.2 and tested and this problem still exists in 4.2.2

Same here, pls fix

Same in my NExus 7 with 4.2.2. waiting for a new release, google?

Took me one day to notice I also have this problem on my 4.2.2 nexus 4. Even in "safe mode" The second a Bluetooth device becomes active WiFi drops out, the bar goes grey or disappears. How can this problem not have more publicity. Any news of a fix on the way would be much appreciated

Fix asap!

I have the same issue in my Nexus 4. This issue is not random. But its there in all Nexus 4 devices and consistent.
@google - please fix this ASAP.

Pretty amazing that this device was released in NOVEMBER and such a bug was not discovered before release or fixed 4 months later.
This is basic QC testing of such devices. They might have used such a cheap BT/WIfi chip to cut costs that it might be impossible to fix.
That's LG quality for you.
I went back to the Note II because i can't work without BT and WiFi for my voice calls.

Google, this matter needs attention.

Same here. Pretty useless when used wifi+bluetooth. I am connected through slimport to my TV and BT mouse and keyboard that seems to be working fine but WiFi keeps dropping connection, it just disconnects and does not even see any networks and the, after some time, reconnects. So even a try to watch youTube over wifi while having any BT devices connected is not possible. This needs fix it sucks like this! And we need option to shutoff screen while HDMI connected ... Come on google developers you are working for 100k salary make this happen and fix it.

I have the same issue. But just occasionally. I have the impression that the wifi keeps connected when it's under "heavier" use (e.g. pings from a computer). But if it disconnects from wifi i'm able to reconnect it with just entering the wifi settings screen.
I will try some more in the next time.
