[Q] Nexus 4 Wi-Fi issues.

First - Hi all, long time reader but this is the first time I've needed to start a thread - so sorry about my first post being a problem/Q!
I've not had my Nexus 4 long, but have got some pretty annoying Wi-Fi issues. I've searched for answers but it seems that people have different Wi-Fi problems and I just wanted to see whether my issue was a common one and, if so, is there a fix on the horizon?
My issue is that I can connect to some routers but not to others (work, home, most open networks)... when I connect it simply says "saved, secured with WPA/WPA2" but wont then connect.
Phones running stock 4.2.1 with franco kernel r28 and the things I have tried are:
Resetting routers
Assigning static IP address
Wi-Fi direct from my Nexus 7
Cleared cache from recovery
changed the Wi-Fi band from 'Auto' to 2.4Ghz and 5Ghz
Flashed new kernel
Very frustrating and because of my signal the lack of Wi-Fi has made me go back to my old phone while I wait for a fix... which connects perfectly to the networks (S3 running CM 10.1)
Is this a 4.2.1 issue - as seems to be the consensus with other Wi-Fi issues or possibly a hardware issue?
Thanks for any info!

There's one fix you've not tried which might work for you (it didn't for me). You would have to be rooted though, which is going to system/etc/dhcpcd and changing the permission on dhcpcd-run-hooks to read and execute from "others". This help some people out but turns out for me that my router isn't compatible with my phone. (DSL-2780).

I've noticed that some of the mobile devices(eg iPhone 3gs, SGS2) are quite sensitive to wireless channel which your router/ap broadcast on.
Try manually switch to channel 6 or 8 that solved my issue - I don't believe in incompatible routers usually problems are related to config.
It is more complicated with an access to the public WiFi as you can not modify the setup.

I have tried this on the routers which I am able to change the channel of and it didn't change anything.

Just to update.
I've now tried this and still can't connect to the affected Wi-Fi networks, probably going to have to wait for 4.2.2 to see if that fixes it...

I had troubles connecting to my wifi network here in my house, which worked pretty good with my galaxy nexus, what i did and worked was deactivating the option "avoid poor connections" in wifi advanced settings, you should give this a try

Fixed it for me

Thanks Chad, it was driving me crazy the constant data drops I had when trying to listen to streamed audio in XiiaLive Pro. Which worked flawlessly with my old HTC Desire.
Did as you said, and perfect now.

I too have wifi issues with my N4. We have several phones at home - an HTC Aria and believe it or not the SGS1, SGS2 and SGS3!
All of them connect with no problems. My brand new N4 will see the router but refuses to connect until I toggle wifi on/of serveral times in succession, sometimes 6-8 times!
I have avoid poor wifi disabled but it does not help
I really hope El Goog fixes this asap as it is very frustrating.

I've had this issue forever. Android phones hate low or overcrowded signal. Though my nexus 7 always works fine. Makes me think it is the lack of WiFi antenna strength

BLUETOOTH not WORKING WHEN WIFI is TURNED ON AND CONNECTED

aka "Bluetooth kills WiFi"
google nexus 4 4.2.2
Build number JDQ39
When WiFi is turned on, AND CONNECTED, and I make a call using Bluetooth device the connection starts cutting. The WiFi icon in the notification bar disappears then appears again, the radio icon starts connecting/swapping between to 3G or H also the 3G/H icon changes from blue to gray, during this time the connection drops.
If the WiFi is off everything works normally. I talked to Google but no help there, it's like the first time they hear of Bluetooth issues.
The issue is same with stock ROM or AOKP built 5 on NEXUS 4
However, I use the same Bluetooth, voyager-pro hd+, with galaxy nexus 4.2.2 build jdq39 and I have no issues with it. not rooted, stock ROM
Any ideas or fix. If it was something to do with rooting or custom ROM why it was not fixed after I restored it to stock ROM? and why no issues using it on galaxy nexus having the exact same software?
Edit: just tried this on 2nd brand new nexus 4 in our household, not rooted or modified in any way, same issue
OK. THAT'S KNOWN ISSUE https://code.google.com/p/android/issues/detail?id=41631
Google Issue 41631

BLUETOOTH not WORKING WHEN WIFI is TURNED ON
I'm having the same issue. Bluetooth and wifi do not play nice. Not sure if its a software or hardware bug.

Pulled a Linksys E2500 5GHz router I wasn't using out of the closet, and disabled the onboard routing crap on the uverse 2wire router. Nexus plays nice with bluetooth at home now, even in 2.4GHz mode. Gave me a reason to stop using the uverse crap, but it's still kind of annoying that the N4 is so finicky with wifi. I'll stick it out!

meh, I am returning mine and sticking to my old galaxy nexus. I need bluetooth ON and WiFi ON all the time
will buy it again if fixed or just get n5

No problems with Wi-Fi or Bluetooth together :thumbup: I'm using MW600..

Do you listen to music only? Do you try to call someone and have productive conversation over the Bluetooth, while WiFi is ON and connected? If the WiFi is ON but connected the problem is not that bad.
I tried with two devices at home, then called a friend, that lives 1000 miles away, with N4. same results. Total of three independent devices tested.
I am using Plantronics Voyager HD+, one of the best headsets out there.

I use my bluetooth for everything.. And works fine:good:

This happens on my N7 running 4.2.2. I have been using a MOGA controller and a Motorola S10 headset.
Everything with work for about 15 min then my network will disappear. When I go into WiFi, it shows no available networks, even though there are like 15 near me.
The only way to reconnect is to disable Bluetooth. Networks immediately show back up and reconnect. Then I can reenable Bluetooth and continue.
I had this issue with MOGA controller originally and wrote them. They said it is an issue with the N7 and N4 and to disable WiFi when playing games. I tested and the controller is perfect with WiFi off.
Streaming Netflix while paired to wireless headset works for about 15 and then quits. I have to toggle Bluetooth to get another 15 min out of it.

Yeah. My N4's been dropping wifi when bluetooth is in use ever since I got the thing. Got tasker to turn wifi off when bluetooth is connected, and vice-versa... Sad I can't use both. Nice to have a 5GB data plan. Comes in handy. But still, should not need to work around it.

I can't even get my N4 to connect to the bluetooth in my car if wifi is turned on. It's supremely annoying. Combined with the not being able to turn bluetooth off (because you can't turn it back on without a reboot usually) it's making me hate this phone.
Anyone else have bluetooth connectivity issues with wifi on?

Tasker - a great solution.
Wish Google/LG fixed this already.
BT/WiFi collisions are a pain in the ass for mobile device engineers. But that's no excuse for Google to sign off on this product with such a bug.

Have excatly the same issue with my N7. According to where I bought it it's a known issue but you can't RMA it since it's a workaround (do not use BT and WiFi at the same time).
It's crap cause I bought the tablet to get rid of cables and use to control my music. Now I first have to download by WiFi and then turn it off to use BT to control my receiver.

If memory serves, Google has actually said this is working as intended and won't be fixed.

wait, so then can someone explain to me how I can stream Pandora over wifi through my Jambox? Is that not possible?

So, anyone got a solution? This is making me very angry!

Yes, the problem in the united states is with AT&T wifi router. So for people in the USA if you have att router or live in area where you have apartment complexes etc and suspect they use ATT you will have a problem. The solution is to go to WiFI settings > Advanced and choose 5G only. DO NOT use "auto" or "2.4G" option. This solves the problem. In other countries would be some other router problem. the WiFi chip on N4 does not play well with some routers around when operates at all frequencies.
That's why the confusion. some people say "all works fine" other reporting problem not suspicion they have ATT router or live near residency with one.
If you rely on wifi mostly and no 5g option then no solution.

Has nothing to do with ATT router.
I have a WNDR3700 and it happens to me on my N4 and N7's when at 2.4ghz (you can see the (dis)conntects)- moving to 5gig solves it but I loose a lot of range... (Just watch your signal meter when you are steaming over net/BT and switch between 2 and 5g - you will see the difference in behavior)
It's a Qualcomm driver issue that has not been fixed - boo on LG and Google for allowing this to get into their flagship devices and leaving it in this state for so long...
I should fire up my old N1 to stream music... Shame...

I have the same issue. I have a nexus 4 stock 4.3 rooted and if I have the wifi on and connected, when I make a call with my Jawbone Era headset I can't listen well the other person. His voice has a lot of pauses. When I turn off wifi everything is OK. This is very annoying.

[BUG] WI-FI not working properly while bluetooth is ON

When I have bluetooth activated connected with any device, the wifi doesnt work properly. What i meant with this is the wifi signal and the network speed. Also the mobile data is not affected by this. So i would like to now if someone is having this problem too?

In this phone wifi and bt are on one antenna (surely)

[Bug?] Bluetooth and WiFi doesn't work in Conjunction.

Idk since when I'm having this issue but it's quite prominent and disturbing, when I'm connected to the Bluetooth speaker and my WiFi at the same time, the WiFi randomly disconnects and connects automatically and in some case the device doesn't even detect my WiFi network for quite a while. I need to confirm whether I am only one having this issue or it is present in others' handsets as well, thank you.

Which system version are you on? Are you rooted? Did you do any modifications to the system?
I'm on the 8.1.10 and it never happened to me

I'm not having that issue, and I use wifi to listen to tune-in radio while using my BT headphones at the gym. Been doing this for months.

I'm on the same version too but I do have that issue maybe it's limited to my phone only. Thanks for the replies tho.
Hey, forget about the disconnecting part but can you confirm if the WiFi drastically slows down when connected to Bluetooth or even that issue is limited to my unit?

@matcho13579 doesn't seem to have the issue so I guess something is wrong with our devices. I'm still confused weather or not to take the device to the service center.

Looks like it's the case. I'm using MiBand 2 as well, so Bluetooth is always on and I'm not facing such an issue (I'm running Stock March update with MetaPhoenix kernel)

My wife's Mi A1 has the same problem too, so I think it isn't a hardware issue...

I think the problem is that there is a problem and it should not be there in the first place also read my original post, I have that sort of issues too.

Hello, I have the same problem... I tried a lot of custom rom with android 8.1, same thing... I tried to modify bluetooth parameters. The bug stay...

I think its a "common" issue since wifi and bt use the same 2.4 ghz band, im not 100% sure about this tbh, but i think this is what happens

Yes, it is!! I tried a 5 ghz wifi this morning and have the same speed with bt off and on. So the problem is the interaction wifi/bt on 2.4 ghz.
I also tested a Redmi Note 4 Global in a 2.4 ghz wifi, with and without bt activated and have no issues on the speed.

Voice quality is terrible when using a bluetooth headset with a voip app on 2.4GHz wifi.
I have also had instances where bluetooth device gets disconnected when wifi is turned off.
My 4 year old phone does not have this problem.
There is definitely an issue with this phone. Hopefully a software bug.

Either it's a hardware issue or the problem is caused by WiFi interfering the Bluetooth signal as they both work on the 2.4Ghz band except if you're on 5Ghz WiFi. If anyone on 5Ghz WiFi has the issue too then this might be a hardware issue. I've sold my phone and got a OP3T and it slightly suffers from the same issue too so I guess it's not an hardware issue after all.

i have exactly same issue on android 8.0

Hi, I was able to solve this problem leaving all the modem / router configurations intact and acting only on the phone without needing root or anything else: it was enough to reset the network configurations of my Android device.
Follow the steps below:
1) Settings
2) System
3) Advanced
4) Reset options
5) Reset Wi-Fi, mobile & Bluetooth
6) Reset Settings
Once completed, reconnect to Wi-Fi (enter the password as if it were the first connection) and try a speed test to confirm the resolution.
Procedure tested on Mi A1 with Android 9 Patch July 2019.

Most my devices experience issues when using 2,4Ghz wifi and bluetooth at the same time. So when i use wifi it is set to 5ghz and work just fine.

In my opinion 5ghz routers are cheap enough to do some update
This maybe some config issue but i am not networking expert.
For example In lg g6 case using 2,4 means that wifi reaches only 50mb/s but on 5ghz its 100mb/s because config is not set correctly.

You might be able to change the channel on your router and find one that doesn't interfere with bluetooth as much. If you google "bluetooth wifi interference" you should find some things to try.
