After OTA 4.1.2 Update, having wifi issues/problem

I was using MrRobinson's stock rooted rom. When OTA 4.1.2 came out, I unrooted, installed patch, ran CF-Autoroot then I'm back to rooted again. However I did notice, every now and then, my wifi stays connected but connection dies. Internet connection is simply dead. So I don't get any email notifications if ever I get new emails. To fix this I have to turn wifi off/on and internet is ok again. I thought maybe I did something wrong so I wipe cache/factory reset, odin back to full stock non-rooted, installed OTA then use Exynos Abuse/Exploit to root. I am still experiencing the same issue. Att Smart Wifi is disabled. Wifi is always on under sleep policy. I have scorched the net and I can't find any solutions Any help would be much appreciated.

Mine is on the oem update no root even, and my wifi sucks now. The signal and connection will be good but it can't up or download anything. Wifi speed and cellular data speeds are all sub 1mbps also. ATT wifi is disabled also.
The only thing that helps me is to just pair to another wifi source, and go back if needed. Annoying! I'd love to find some solution also, I don't mind rooting if need be for it also.

Already have the phone more than a month, don't think I can swap it out
EDIT: Btw, no issues on custom roms, only having issues when using stock rom

You can still do warranty to get a new one just call att and tell them your situation with it. This would be my best recommendation to you. Or just root and keep running roms. This is one phone that I havent had the urge to customize with a rom or anything yet

Thanks for the recommendation but I also felt the same before. I thought the phone was fast enough that I didn't need to try custom roms. After trying Scott's ATT CleanRom SE, that idea was simply change. If you haven't, you should try running custom roms. Although, I would still want to know if there is a solution to this problem when running stock rom.

I've had similar issues since OTA upgrade to 4.1.2... Wireless auto connects to my wireless when i walk in the house, shows connected, but cannot actually download/upload/browse/etc unless i manually turn off wireless and then turn it back on, it reconnects, and works fine. Seems an issue the phone is having transitioning from celluar network to wireless...

Thought the question remains, why when using custom rom, you don't get this kind of problem...

Perhaps it's a minor bug somewhere and the custom ROMs happen to pull that wireless code piece from something other than official 4.1.2 where the bug (if it is one) is located.

Yeah but hopefully it will get fixed soon. As I was looking for solutions, some people think it's their wifi routers that are having issues.

Perhaps it's an issue depending on what broadcast freq is being used by the router.

True, but 4.1.1 didn't have this issue. They must have changed something.

I don't know if it is related to the issue in this thread, but I had a problem with the phone since I got it of the WIFI constantly connecting, then disconnecting, then connecting again. I solved it by changing the security model of the router from WPA/WPA2 to WEP128.

Yeah saw that thread somewhere but this is a whole different issue. Wifi stays connected but no connection to the internet. You get connection timeout.

Yeah mine just quits. A note 1, a note 10.1, 2 ipads, 2 iphone 4's, and xperia ion and three separate computers have had zero issues on any of the wifi networks here. In fact, if I leave it be, it will not work on the phone, and it now seems to block all the rest from access! If I turn the wifi off on this, perfect immediately afterward. Strange.

did you try just simply reset your router?

I had all the problems in this thread after 4.1.2 A factory reset fixed it.

I'm using the international ROM (custom but fairly stock) and started experiencing the same issue when I switched ROMs.
Toggling the wifi always fixes the problem, but it's not a permanent solution. The problem seems to happen when the device goes into sleep mode for me.

I have the same issue, and this is one of the only posts about it. Have you found a way to fix it? I'm at a point where I'm about to just sell this. I can't get anything done. Do you by chance have T-Mobile?

Same issue. T-Mobile here. Doesn't disturb me enough to sell the phone, haven't had the issue since going to a custom ROM. I'm sure it'll be fixed with OTA's or whatever.

Hello
i have the same problem
i am on VIPNET Croatia
is some fix coming soon
it is very annoying

Really nice to know I'm not the only one. But my god, it's getting worse as time goes on. I'm at the point where I can't even get data unless I reboot the phone 5-6 times, and only for a few seconds. I am completely out of ideas.

please can you tell me witch coustom rom did you put in htc M8
and solve the data issue
i am going crazy with this phone
and i want to put same coustom rom like you
to get problem fix
please help

I have been using my m8 since the day I got it back in early April and have never experienced that issue. I am also on tmo but have the dev edition with stock rom but I live in the city so I always get a strong and good signal.

Possible solution
My M8 worked great for a month when about a week ago I've started having serious issues with the HSPA data.
After working great for a few minutes the data stopped working.
The H icon showed that traffic was sent from the phone but no traffic received by the phone.
Sometimes the data connection was restored by itself and sometimes I has to toggle the data connection off/on to have it restored.
It both cases the data connection failed again after several minutes.
All the diagnostics app showen that there was hspa connection.
After trying almost anything I could think of I found out what causes my problem:
It's the F**** NFC!!!
I've forgot that a week ago I've disabled the NFC thinking this will save battery life (though the battery life is great).
Turning the NFC on (followed by a power-down/power up cycle) solved all the data connection problem.
I've verified several times that NFC disable is indeed the cause of my problem.
Hope this helps others on this thread.

SMS Issues since Lollipop update

Has anyone been having delayed text messages being sent and received since the update? My wife has been having this issue with her M8. It's been intermittent but it happens almost every day to her.

I have also been having this issue. Sometimes a text message takes an hour or more for me to receive it or my recipient to receive it, other times I'll receive up to 4 of the same message in quick succession. It mostly happens when I have Wi-Fi calling enabled, as text messages don't seem to play well with it. For some reason, it completely disables the cellular radio instead of working in conjunction with it. Drives me crazy.

My wife's phone has wifi calling enabled but had cellular as the preferred connection method, so it would only switch to wifi calling if there was absolutely no signal. So I don't think in her case wifi calling was the issue. I completely turned it off just in case tho. I'm having her try another messaging app just to see (Google Messenger vs. HTC stock), but I don't think that's the problem.

Also remember that the only app that can send mms messages over wifi calling is the delivered one that comes with the phone. Any 3rd party apps (like handcent, chompsms, etc) will not be able to send mms messages over wifi calling.

Hi, I had the same problem plus mms would be sent nor downloaded. I was using the messenger google app though, switched back to stock message app and it resolved the issue

I called T-Mobile and they had me clear the cache from the Messaging app, and then reset the APNs back to default. So far so good... Everything started working.

I spoke too soon. She's still having the same problem. Reboots always fix it, but it's getting annoying. Guess next step is a factory reset. :what:

while related but unrelated, I had to do a factory reset after the lollipop update b/c my wifi was having issues that seemed random.

I don't think she's had any issues with wifi but i'm not really sure. I know yesterday I was trying to back up her phone preparing to wipe it and I saw the wifi would go out then come back on. I was about 10 feet from the router and everything else on wifi was holding steady except for the phone. Is that similar to the issues you were having?

My issue was that the wifi would connect and then drop then connect. Also some wifi AP, it would work great. To me it was just inconsistent, so I figured in for a penny in for a pound and just wiped the phone. That worked for me, but it if didn't I was planning on re-installing TWRP and some custom ROM as my bootloader was unlocked (but I was still s-on).

Any further solutions to this problem of intermittent delayed text messages? I now have 5.1.1, and use Hangouts. I also sometimes don't get calls either, it's like the cell antenna just turns off.

From what I remember a hard reset fixed the problem for my wife's phone.

GPS signal lost

The GPS signal gets lost 2 mins after I start navigation.. Any ideas? Help?

Sorry that this exactly the type of post one hates to read when in your situation, my GPS experience has been the best I've had with any other phone, haven't tested after the recent update which broke some things for most of us.

ditto Litoven. Very good gps on my ZF2.
Have you done anything non-stock'ish on your phone, resource88? That would be the first place I would look.
If you haven't done anything odd w/ the phone, then I'd recommend getting it replaced since it just came out it's under warranty.

I may have deleted some apps after rooting but I wouldn't know what would cause the GPS to lose signal. At first I thought it was due to the phone being in my pocket but it loses signal while holding it as well. I don't remember this happening when I used GPS before rooting but I could be wrong.

I factory reset my phone, tested GPS and still get GPS signal lost & " searching for GPS". Now I have no clue what's the problem.

I had this same problem. Somehow it just fixed itself on my phone, I think after the next reset. I really don't know what might have caused it to constantly lose lock at first.

Yea I think mine fixed itself because I used it yesterday and it didn't lose a signal.

For Zenfone 2 GPS troubleshooting, recommend using the pre-installed ASUS app called 'ASUS Support.' There are several helpful tips regarding basic troubleshooting techniques for your device's software and hardware issues.

Question Some apps and websites not working on 4G/5G

I have this weird bug since day 1 where some apps and websites never load using mobile data but working on Wi-Fi. At first I thought it's my data that acts up but the thing is it's working when I turn on my VPN:
