[Q] Mobile Network Randomly Dropping - Nexus 6P Q&A, Help & Troubleshooting

So, I am not sure what the cause is but I notice when I go to school my Mobile Network randomly drops and comes back. My buddy also has a Nexus 6P and his never drops. Is their an app to reset a Mobile Network? I used to have this issue on my Note and putting the phone in airplane mode for a little would fix the issue but it isn't working on the 6P

Nexus 4 losing mobile internet when idling a long time in wifi

Hello all,
currently my Nexus 4 is losing it's mobile internet connection when i am a long time connected to a wifi. I am on O2 germany as a carrier, when android was much younger, like 1.6 i had the same issues, but somewhen on android 2.X it was fixed.
Somehow it looks like in 4.2 it's now the same issue
When i am just a few minutes in the wifi and lose wifi connection like moving away from the building everything is fine and the nexus 4 is switching to mobile internet
when i am a few hours in the wifi and to the same it's not switching, i've got cell connection for call and text but no Internet,
switchting from 2g to 2g/3g fixes it then, but it's somehow annoying
any ideas or anyone with the same issue?
edit:
seems that people are having the same issue on the galaxy nexus too, but even with older android versions

it actually happens to me as well. I live in Australia and thought the problem lies with my provider. And yeah I can get the 3g connection back when i tried to change to 2g then back to 3g connection. Has this issue been reported before? hope it can be fixed soon.
This has happened to me twice since I got my N4. I'm in Canada btw. I wonder if it is a frequent problem out there.

Me too...is there a fix?

my solution so far is: airplane mode on -> airplane mode off
This is what I usually end up doing. Although it sucks that a phone of this caliber has problems with this.

Im having the same problem. Doesnt matter which rom im on. Been on stock, modaco, and some PA rom with this problem. Also used matr1x kernel and franco kernel. Solution for me is to jump into airplane mode and back.
I'm in the same boat and only quick fix is airplane mode on/off.

I have the same issue.
I dont know whose fault it is, Google, LG or my carrier... but it's quite frustrating from time to time.
I thought i had solved it by activating "choose automatically" in mobile network settings> network operators.
It worked yesterday and this saturday, i didnt drop 3g connection when i disconnected wifi.
But i lost it again this morning as i left for work, just like last week...
I've had this problem since 2.1. I seem to remember it being on the Google fix boards. The aeroplane on/off is the easiest workaround. But, still, it's annoying, and it is also not consistent. If it makes you feel any better, the same issue arises on iphones. This suggests it is not simply an android issue, it might be interesting to know if bb or wpx does it.

i think the issue is neither LG nor Google
i think it's something with qualcomm driver and the provider
because on older devices i had with qualcomm chips had the same issue
the sgs2 and the hox which had exynos and nvidia chips didn't had the issue

Idk if knowing that others have the same problem makes me feel better, i just hope they can fix it.
That's likely the one, I'll rely on your veracity.

I have the same issue, and not thought about the airplane mode. Thanks guys

so if you check the google support forum thread
it looks like a lot of users are having this issues
i don't undersand why google is not even giving a statement
It happens to me very often, because I turn off data overnight. Airplane mode doesn't help, the only thing that brings connection back without reboot is Mobile Networks -> Network operators -> search... It finds my operator again and connection comes back. I had the same problem with Galaxy Nexus 4.1.2 (fixed in 4.2, though), but airplane mode did the trick there.

Internet stops working when left idle for long
I bought the phone a week back & am facing the same problem.....not just been with Wi Fi even if the phone is left idle the internet stops working & i have to restart......post that it comes back to normal & active.
Its quite annoying to restart phone every now n then everytime internet stops working.
Also, tried Airplane mode on/off its worked.
Are there any experts that can help to resolve the issue for a better & permanent solution....?!

[Q] wifi & mobile network grey bars

I recently bought my wife a nexus 4 abs she's been having a problem where when she disconnects from wifi her mobile network won't connect, it says 4g but it's greyed out. I know she should still have connection but she doesn't, everything just times out. Only thing that fixed it was a reboot, anyone else experience this issue? And she's on stock rom, not rooted.

No worries it'll reconnect to the servers.

This only happens to me when my WiFi connection decides to disconnect! Both my Service and WiFi gray out when my WiFi does not work. I have a terrible at&t internet service! But other than that it works properly.

Does it just never turn blue after turning off wifi? Its supposed to turn off mobile data when wifi is on to save battery. It could just be an issue with your carrier
Well like I said a reboot does fix it, from what I understand it's just when disconnecting from wifi. The time interval was about 10 minutes and her mobile data still wasn't connected. We're on tmobile btw. I thought it might just be an n4 issue, I don't experience that issue on my one.

4.3 keeps dropping internet connection?

Hi, I've had my nexus 4 for about a month now, when I got the phone I automatically updated to 4.3.
Since the very first day I've had it, it has kept dropping internet connection randomly multiple times everyday? The signal bars will go from blue to grey and stay like that until I either reboot the phone or turn on airplane mode then turn back off again.
Its becoming a constant hassle trying to use the internet because it keeps hanging.
Has anyone else come across this problem? If so what did you do to fix it?
Thanks alot

Do you mean WiFi or carrier data? And how good is your carrier signal? You can try flashing a different baseband.
For WiFi, try turning off Wifi Optimization.
Its the carrier data that keeps dropping, I also get full bars most of the time.

Its surely a baseband problem..nothing to worry..
Just try different basebands and test them and see what works for you,but for that you need to be rooted..
Before you asking or creating a new thread refer to efrants thread for unlocking and rooting.:good:

Wifi issues do I need to switch while I still can

I just got the s4 and its total stock but it keeps dropping on and off wifi. In fact in settings it sometimes says I have poor wifi conection. But I know my router is good and my wifes g2 has no problems. I read online there is alot of issues sinve the 4.3 update and even after the patch. I also read samsung is not going to do anything there blaming sprint or your wifi. Should I switch to the g2 while I still can or hold out for a fix or does anyone know a fix?

Also it took 4 hours to set up phone. Most was the crazy slow download of apps from play store and updates from play store. Small apps would take 10 minutes to download then about 5 to install while on my wifes g2 same app same time downloaded and installed in under a minute

WiFi switching on and off is probably under wifi settings. Just turn it off and it will stop switching on and off.

I tried that even did the ##code to get into WiFi and turn off WiFi saver. Nothing worked and then it started saying no mobile data connection but I was on lte and it worked. Plus I was getting that Knox problem so I just went to the g2. Thanks though

Keeps losing LTE data!

Nexus 6p on nougat 7.0 every once in a while the LTE symbol disappears and I have no data. Only fix is to reset phone! Tried toggling cellular data, and toggling airplane mode, sonar it's worked once to return data. Otherwise power cycle returns data. Anyone else experiencing this! Phone is refurbished but has been working great. Just trying to figure out if this is software or hardware related....thanks.

Same here!
Via Nexus 6P
Every few days i see H+ but that's about it. No loss of data here and on Nougat 7.0
Did you do a Factory Reset after you updated? If you didn't I would recommend that if it persists.
LTE issues has been around for a long time. What carrier are you all using?

T-Mobile....yes did factory reset.

I am on Nougat and my reception has decreased. I am on AT&T and I'll be on H+ while an iPhone right next to me will be 4G with 3 out of 5 bars. Something is up with the radio on Nougat........

On T-Mobile here as well having the same issue, LTE will disappear and I'll get a notification saying Data Service is blocked and a reboot fixes it for a bit then I lose service again.
Mine in T-Mobile was doing it too...

Those LTE issues were fixed (for most anyway) a few security updates ago.

Am on the latest version of N and have been experiencing the LTE drop on AT&T for quite some time, even on previous versions of M.
Now my.freaking texts are starting to not go thru. Random. Only cure reboot. So battery sucks, losing data, and texts randomly fail. Ugh! I want a mr1 or marshmallow back!

The software itself yes, but carrier wise no.
T-Mobile has been having ongoing LTE issues for some time now in some areas. When I had my Note 5, had to constantly reboot to get LTE or any other data connectivity back.
I think it's only the T-Mobile and Project Fi (T-Mobile side) are having issues still.

Same here and when it happens, i use app lte on off app. Easy.
I have this same problem on TMO. If I try to use any radio higher than 2.50 (have tested all the way up to 3.75) my data will suddenly drop completely out of nowhere and not come back until I reboot. There seem to be certain areas near me that always make this happen when on those radios. I wonder if this is a regional issue or a hardware issue, doesn't seem to affect that many people.
I've also been dealing with issue. I'm almost certain it's an issue just with T-Mobile and maybe the phone communicating with towers. Went to d.c. not too long ago and didn't experience any issues but the same day I retuned to Pittsburgh the issue returned

My stock 7.1.1 6p on t-mobile has just recently been having this issue. I was considering factory resetting but my wife's 6p sometimes has the same issue so maybe it's t-mobile. But why would rebooting fix it? Is this still a problem for other people?

This issue seems to be occurring to me as well. T-mobile is my carrier. It is really annoying since the only way out is to hard reboot the phone. You can't go into airplane mode and turn it off to get a signal like normal. Not quite sure what the issue is. It has happened on both stock and flashed roms. I have tried to see look at a logcat of the problem but it is a bit above my technical understanding.
I'm on the latest radio and bootloader and the problem is still occurring.
I think it happens when:
- Going away from wifi-coverage
- Going into area with poor cellular coverage
It's possible that being on 2G/3G may avoid the issue, but of course the speed sucks. I just tried going on 2G/3G and toggled wifi a few times. So far, mobile data is still ok. But the instant I enable LTE, mobile data is loss. Switching down to 2G/3G doesn't help. So another possible cause is:
- Switching from 2G/3G
My guess is that there is a bug with the LTE code on the phone that got introduced with a recent update.
Has been happening recently to me too as of last week. Random connection dropping for a few seconds. Usually, it will reconnect quickly and it'll show full signal, then it might die, or it might stay connected.
