Weird wifi behavior - Nexus 4 Q&A, Help & Troubleshooting

Hello everybody since a few weeks I've been having a weird wifi problem. Sometimes, at random times the wifi disconnects from the network it has been connected on for a while and if I go into wifi settings I see that there are no wifi networks available at all. The only way to fix it is to turn it off and on again. This is really annoying expecially for missed emails and notifications. I really don't understand what the problem is. I've tried 2 different roms, pac before and slimakat now, always doing clean installs. I've also tried different kernels and I'm now on hellscore. I also tried different radios including hybrids (I use one now for lte). Nothing seems to make a difference... Could it be some kernel undervolting setting? I also have suspended back off wakelock, but I guess that's another issue. Also I tried wifi optimization on and off... Any help is appreciated. Thanks

If flash the factory image and see if the problem still persists. If it does you probably have a hardware problem

Ok thank you. Could undervolting be influencing it? It mostly happens when the phone is in deep sleep or when I get outside a building and I'm connected with wifi and then I got out for a few minutes and back in again...

[Q] How many of you are experiencing SOD issues on the Nexus 4?

Hello everyone,
I would like to know how many of you are experiencing the different kinds of SOD on the Nexus 4.
I found few references to the SOD issue, but no one could tell exactly why this is happening.
Some say it's a software issue (some say it only started to occur at JB)...
Some say it's an hardware issue.. some of them RMAed, and got a new phone with exactly the same SOD issue.
I would like to dedicate this thread to this problem and see how many other Nexus 4 users are experiencing this SOD.

Never had one so far. Running stock 4.2.2/Franco kernel nightly_110
-Edit- currently undervolted -75 mV.
just stop messing your phone up with stupid OCing and benchmarks... This issues are installed to protect the hardware from crashing... ( Red light of death... )
My phone just fine. never had this SOD.
Never had an issue on this device. On my old phone, dropping the min CPU speed too low would cause it a LOT.

You don't have an option for unable to turn on phone without a reset: no blinking led. This is also a scenerio.
Please take a look here! http://forum.xda-developers.com/showthread.php?t=2195278
I've tried almost everything (wipe& re wipe , install stock ) and nothing seem to solve it.... most frustatin thing is when I hit "home" after playing heavly and ...bamm it goes black screen & hav to reboot pressin home&vol+
Are you using a custom kernel to undervolt? That can cause SOD.

Im using it now (customROM&UV) since it doesnt affect my issue.... I tried completly stock for 2 days and keep crashin... or at least on g.earth as I didnt install any app/game to be sure its not an app related issue.
Cant figure out what happens, it can play games w/o any issue, but sometimes when I change orientation it just goes black
PD: I dont hav enough time, but ill do a logcat to see what can possibily make it freeze
My case is not listed in the poll options:
- the phone went into standy, good battery, no calls, no high loads;
- LED was inactive totally.
- then I was unable to turn it on normally (only through reboot).
While in this state, trying to call the phone resulted in "long" tones, i.e., like the network saw the phone. The phone did not ring.
This happens with the latest stock firmware on the 2nd day of my use. Non-reproducible. Phone returned.
Would be delighted to learn if that's a hardware or software issue
Not necessarily SOD but experienced extreme battery drain under these situations
1- Charging via USB and left phone connected after PC shut down.
2- Charging via Wireless Charger left it on the pod.
In 1st ASA pc is shut down
and
In 2nd ASA Phone charged completely , as I suspect the charging process goes backwards ! It someone drain current from your battery to the power source.
AFAIK none of these issue are positive with normal good old AC charging. However you can still use a workaround by using the app called "Safe Charge"
This is my experience

Does Nexus 4 still have delayed Wifi notification issue?

EDIT: Just read a thread that was 4 days old that says the issue still exists unless using a specific kernel that fixes it. Mods can delete.
Bug is still here.
I haven't experienced the bug. Only had my Nexus for four days though. Maybe I'm just lucky.
The bug is still around, but it seems to depend on the model of router that you have - i.e. some people get it, some don't.

When I'm at home my phone is always connected to Wi-Fi and pretty much in deep sleep since I only use my tablet unless I'm making a phone call. As soon as I get a gmail message or talk message, I hear my phone go off at the same time as my tablet. I would imagine if this bug existed on my phone there would be some sort of delay..? Perhaps the bug only affects certain message apps?

It might depend on router model as well.
But clearly changing those setting doesn't help
You can fix it by editing configuration in a file and rebooting,
however, someone said this will cause some small effect on battery life.

Hi everyone.
Last year I changed many smartphones, but notifications delayed have alway been with Nexus devices over 3G network.
I had a Gnex and now a Nexus 4, and this problems is exactly the same over and over........delayed notifications on a variable time...maybe 15 or 30 minutes.
Everything ok instead with other terminals as SGS2, SGS3, Xperia S, T and Z.....
How is it possible that after many years Google has not yet solved ? bah...

[Q] Google Nexus 4 Loses Network Connectivity

Hey guys,
I recently got a Google Nexus 4 and it seems to be losing the network connectivity frequently.
It keeps saying No Service / Emergency Calls Only.
I haven't made any changes to the phone yet and its still running on Stock Android (Android 4.2.2)
I read few other threads on this forum and came to know that there are others who are facing this issue
and one of the solutions is to reboot the phone. However, doing this frequently doesn't seem to be feasible.
I'm in roaming. Could that in any ways be affecting the network signals.
Please let me know if there are any other solutions as I would like to avoid using a custom ROM/ CM as of now.
Thanks in advance
It's a known nexus 4 issue. It has been reported. Let's hope google modifies that for newer releases if it's a software issue and non hardware...
Cheers!

So till it gets fixed, rebooting the phone is the only solution ? Would frequent reboots (say every few hours) do any kind of damage to the device ?

Not totally true....
I replaced my antenna section and this solved my problem.
So it can be hardware related for some.....
Others solved it with a new sim card or flashing the latest baseband. But its a known and annoying problem.
I tried everything and the last option was replacing the antenna section. I work in a mobile repair centre so it was no problem for me.

I reckon it could be due to the sim card, cause the card is kinda old (4+ yrs). Don't think its an issue with the antenna since it works fine in the home network. Only while in roaming it keeps flipping a lot.
Will try and get a replacement SIM for this. Can you point me to some tutorials/guides for flashing to the latest baseband.
Some can solve their problem by enabling and disabling airplane mode instead of a full reboot..worth trying.

Have tried that. Isn't as effective as the reboot is. Hope Google fixes this soon
Hey guys
Just curious, could a factory reset help alleviate this issue ?
I have that problem, when I dont haVE roaming enabled. Enable all roaming and it should be good
Recently faced this issue.
And how can this be a hardware problem when not all are facing it? If minority is facing this issue than I doubt it's a hardware fault.
I noticed when I am undervolted past -150 I tend to lose service frequently.
Sent from my Nexus 4 using xda premium
I have that problem, its very random. Lately though everything works fine, voice, ect. My data though is another story. I have the custom APN in, and my data goes from 8-9mb down to less then 1mb, then no connection back to 1-2mb, back to 8-9mb. Bizarre to me. I work in IT, so im on wifi all day every day, its not a huge deal just really annoying. Most of the time though, just using airplane mode fixes any connection problems i have.
I have tried the Airplane Mode. Doesn't help at all.
And even I have noticed that if the signal strength goes beyond -150dBm it does lose the signal. Happens more while in roaming.
No solutions other than reboots so far.
Flash the 27 modem it fixes a lot of this

4.3 Wifi issues?

Anyone else having wifi issues with 4.3? I am 100% stock unrooted, installed the official google factory image with fastboot doing a full wipe including user data. I have been running AOKP and have gotten sick of the issues this tablet has and though that going 100% stock to see if it solved any of the problems. I have only been installed since last nigh but I am already having wifi issues. The wifi seems to loose connection and has to be toggled on and off to get it going again. Anyone else seeing this?
I can confirm this.
I actually think my Wi-Fi is even better now.

I had the issue you described on 4.2.2 but not so far with 4.3, only time will tell. I'm getting random YouTube app freezing but these do not appear to be WiFi related. I flashed the 4.3 update over my existing 4.2.2. Stock image so have a different base then yours.
No problem with WiFi, it also seems more stable now.

As others have said, I've found my wifi reception/stability has improved with the 4.3 image. My older 802.11b hotspot didn't work with the N10 reliably before the upgrade to 4.3, regularly dropping the connection. Now it works fine, and always at full "bars" reception.
My 5Ghz 802.11n AP worked fine before, and still works fine now.
Hi, I too have had poor wifi on my wife's nexus 10 since 4.3.
Every night for last couple months my wife and I have played ticket to ride in in bed. From the moment she reset it to apply the 4.3 update (between games) she has suffered from dropouts and the game continually disconnects. Was running perfectly for months until this update was applied.
Given that she updated between games and we noticed the issue immediately after the update I am sure there is a change for the worse in the wifi configuration under android 4.3.
I am also experiencing wifi issues with the stock 4.3 update. No SoD so far like with 4.2.2 but since 4.3, wifi quality will degrade when I am using it heavily. I will still have 2-3 bars but the connection will slow to a crawl until I toggle wifi off/on. (I feel I should add: quality router, multiple devices without issues) The only thing I have done to this ROM is chainfire root. It seems some have the issue and some don't. I'll prob try and install again tonight to see if it helps.
I have been experiencing a loss in internet connectivity after 1-2 hours of inactivity now that I am on 4.3. The WiFi icon turns gray but stays connected to the router. I rebooted the router, but no help. I have advanced settings set to WiFi always on. I had WiFi optimization on, and am now testing to see if things change with it off. I never had any connectivity problem with 4.2.2 and nothing else has changed. If this keeps up, I may flash back to 4.2.2 till things get better.

That is a very simple fix if you just asked around, or searched and you would see the three primary causes.

I ended up using an app called safe charge that seemed to do the trick. What were the other causes or fixes for this? I just wanted to go stock for a bit while AOKP and CM get the 4.3 builds up and running so i would have a reference to compare the performance and stability to.
I have filed a bug report for this here https://code.google.com/p/android/issues/detail?id=58206&thanks=58206&ts=1375129699

The leading causes of sleep of death issues are:
The CPU governor uses hotplugging, the majority of the users on this tablet get SoD with hotplugging on
Voltage was tweaked a bit lower and is not enough to run your CPU properly
You are running Franco's R12 kernel which has a very widely known SoD issue.
It is also possible that the version of the AOKP kernel you may have been running had the same tweak that Franco did and was also causing a SoD. 90% of the time when someone has a sleep of death issue on this tablet it is because of something from the kernel that is causing the issue, you can try out KTManta or Trinity kernel (also both of them have beta kernels available for 4.3).

FWIW, after turning the WiFi optimization off, the WiFi status icon has remained blue and I have not lost the internet connection when sitting idle for hours.

WIFI Drops after in deep sleep

I'm having this issue:
Wifi will drop connection after a period of time when the screen turn off and when it enter in deep sleep (some seconds after the screen is turned off). Shows normal signal strength but I dont receive the notifications (whatsapp, maildroid, etc,etc)
With mobile network does not happens.
If you want to try this issue, turn off the screen, wait 1 minute and send from other phone a whatsapp message to the G2, in my case the notification will never appear.
How many of you has this issue?
It happened in Nexus 4 and seems is happening in Nexus 5

"keep wifi on during sleep" doesn't work, even people with the new Nexus 5 has the same issue
Maybe it's your router timing out and losing it upon reconnecting (stuck in connected state)? I once had that problem on my Spectrum and know it was a part android issue. Had to set a static ip between router and phone. Issue disappeared when I went to CM. No issue on my G2 with "shadow connections" or disconnects.
check your battery saving settings, with one setting, switch off radios when not using this occured

First, pure stock and had the issue, now Rayglobe and the same issue... I dont know if its a fault of the 802B ROM, I want to understand this.
If the battery charger is attached to the phone, there is no issue...
I can't wrap my head around it. Tried and not having issue plugged in or not. Try the static ip. I had the issue with my Spectrum ONLY on my last router with many other devices connected. The hardware and software combo just didn't get along dynamically. That device was the last I have seen the issue.
