Odd connection issue

It started yesterday and I don't know why. Go to check my weather, hit update and after about 10 seconds I get a bubble telling me that an unknown connection error ocurred and to try again later. I can make phone calls, send and receive texts, but can't check my weather. If I soft reset it works fine. Today, go to check my weather again and same problem. Been making phone calls and texting all morning without issue. Soft reset and again it works fine. Obviously, something is going wrong with my data connection over time, but what could cause it to just shut down completely requiring a soft reset to fix?

More weirdness. I tried manually turning on my data connection in the Connection Manager and as quickly as I turn it on it turns itself off. WTF! I haven't done/added anything to the phone in a week. Is this something on AT$T's end, could they be blocking me from using data for some reason?
About 2 weeks ago I did some regedit to have the data connection turn off automatically after 5 mins of non-use. It was working fine after that and anytime it needed a data connection it would make it. I don't remember where the setting was to change it back, but I doubt this is the problem because this issue just started yesterday.

I'm on AT&T also, on the new leaked ROM, and I have exactly the same issue. It started about 2-3 weeks ago, and I noticed the connection drops overnight (during the day I have no problems), and it'll only come back after restart or reset. I think it's AT&T's network...

Maybe they work on improving their towers and network lol

T-Mobile does that also.
i get a Could not coonect bubble,and have to manualy enable my data conection.If you guys are Tethering our providers automaticly drop our priority level...Unlimited my ass,they tried to cap me at Edge speed and all i had to do was disable/enable the data conection to blast 3g...

I found the problem, but I still don't know what caused it. I'm leaning towards something done on AT$T's end. I have always had my phone configured to use the AT$T ISP in network properties. Apparently, it no longer likes this setting. Switched back to MediaNet and all is working just fine. Problem is that when I first got the phone I did speed tests using both settings and AT$T ISP was faster, so that's why I set it that way. I can't test it now because it won't stay connected with that setting. Can AT$T block users from a particular connection? I don't tether and the most data I've ever used was 280mb last month. Hardly a reason to block me.

I'm not thethering either, my usage is roughly 600 MB/mo and my network is already set to MediaNet. This problem started recently, didn't have it before.

Looks like it is something going on with AT$T. A number of my friends from different states have reported issues over the past 2 weeks with several having severe connection issues the past few days. These are people on varying devices including iPhones, Blackberrys and smartphones. I hope it is due to AT$T finally upgrading their network and not overload from all the new iPhone users and abusive tetherers.

Are u experiencing any issues with network connection?

My s3 randomly loses connection to the network. Today I picked up my phone to make a call and noticed it was not connected to the network and displayed Emergency call only message.
This happened a few times before too. Initially, I thought it could be a buggy sim so I got a brand new sim from telus. But its still does it. Randomly though. Any thoughts guys?

Anyone?

I haven't really noticed any issues, but I'm on AT&T. What ROM/firmware/modem?

I had similar problems till i disabled LTE. It was trying to connect to it all the time plus it was killing battery.

me and my brother have had the issue in dowtown ottawa on rogers. seems fine in my apt in the market but on a patio and at a restaurant it just wouldnt work!! couldnt send texts, or receive, couldnt call, sometimes it showed i had full bars and lte but couldnt do anything. my brother complained about this the day before. i will try disabling lte next time

Loosing internet connection while on 3G

Hi, lately I've been suddenly loosing my data connection for 3G/4G, and the only way to solve it is to turn the phone off and on. It seems a random event, sometimes I've noticed it after leaving the phone unused for a while and sometimes while surfing on websites. The icon on the status bar and the signal strength bar doesn't change at all, but still the phone refuses to connect to any website or check email. I've tried turning data on and off, and also going to airplane mode and back to phone, and it doesn't work. I'm on AT&T, with rooted ICS and tethering.
Is anyone else having this problem?

Which baseband you using? I have been using ICS using the .111 baseband with no issues in connectivity for a couple weeks.

I was having this issue yesterday while I was out. I would lose data even though it said I had it. Rebooted and has been fine so maybe some tower issue?? I am on the .111 ics baseband.

I also use the. 111 baseband. I've been using it for a month now, but only noticed the loss of connectivity for the last 10 days or so. Could it be the APN config? I searched around for configs, and noticed that some were missing fota and admin apn types. I've removed them, to see if this makes the problem go away. I've traced the tweaks I did, and I included these two in APN type about 10 days ago.

That has happened to me randomly the past few days, as well, using baseband .111 with rooted ICS. It, however, would not even have the icon that I had internet, the 3G/H/4G symbol would just be missing with only cell service bars. The first time it happened, my APN totally disappeared without me touching anything. The next couple times, the APN was just no longer ticked. Ticking the box (circle) works and I instantly have data again. Hope my situation helps others. I just wish there was a permanent solution to this bug.

It happened again today, I still had the 4G icon (I was in a LTE area) and the APN was still ticked. Again, after a reboot the internet worked normally.

Hey I've been having the same problem too!
At first I thought it was because I was using Straight Talk (prepaid) but I popped in the SIM card on my work phone and started noticing the same thing.
Long story short, I went into "data usage" to disable "set mobile data limit" thinking (what's the point if my data isn't working) and presto! All my emails and fb notifications started spitting out.
I think it was because I had "restrict background data" enabled as well.
While I was having this issue Mms was still working.
Screenshots attached...

Thanks, I'll try doing this and will post back if I don't get the problem after a few days.
===============
After almost a week with the mobile data limit disabled, I haven't lost my data connection yet.

Was on the phone with ATT today and they said the storm did cause some issue with the towers so maybe it will not happen now. I have not seen this issue again after that one time.

Network connection drops and squeeze for assistant stops working

Just checking to see if I am the only one having these issues.
I have the 3 XL on ATT, and I randomly have no internet access over mobile data, even though the notification shows LTE and decent signal strength. Screenshots attached to show what I'm talking about. This has happened about 4 or 5 times since I received the phone a few weeks ago. I went to ATT and got a brand new sim, thinking that my old sim may have been going bad, but that did nothing. Only way to get the mobile network connection working again is to reboot the phone.
I have also noticed a few times that the squeeze for google assistant feature will stop working, and I have to reboot the phone to get it working again. Anyone suggestions? I am leaning towards just doing a factory reset this weekend, but I would like to avoid that if possible.
Thanks

dont know about the edge squeeze assisit not working (i use edge sense module and app) but i have to reboot or go into airplane mode to get data to work when i get the x. maybe using a different apn would help... im on att too

AT&T issues
This is now a problem for me. I have to put my phone in airplane and then back to lte at least once a day in order to get mobile data working again. I'm not really sure if it's a network issue or a phone issue.

Issue for me here too, but I'm in Australia on Telstra network.

Pixel 3 and Pixel 3 XL Wifi causing dropped calls and dropped mobile data

Both my wife and I have pixel 3's, I have the XL and she has the regular. Both were preordered and delivered at the same time, and we are both on AT&T. Since the beginning we have experienced random issues such as the phone dropping mobile data completely even though the signal shows LTE , and having to cycle airplane mode off and then on again to get data back. The other issue is that we both experienced call issues where our end would drop and we could not hear the other party, but they could hear us fine.
I think I may have traced these issues to WiFi causing the problems. When the data drops, I notice that my wifi is on and occurs when I am not connected to wifi (such as an unidentified network) and on LTE, or when I leave a connected WiFi area (like my house) and keep wifi on. We would have to cycle airplane mode to fix this.
For the calls, I had a call drop yesterday and when I looked at the notification bar it showed connected to wifi. I immediately turned off wifi and the call came right back. I thought this was an AT&T wifi calling issue, so I turned off wifi calling. Today, I was at the post office and had to make a call. Soon after connecting, the call dropped. I checked wifi and it showed unidentified network (not connected), so I turned off wifi. The call immediately came back.
So now, wifi is completely useless to my wife and I. Assuming I don't experience any more dropped data or calls, I cant use wifi to ensure good call quality and constant data.
Anyone else experience this? Could this be an RMA issue? Seems weird that it is happening to both phones. Is there a setting we should turn off that could be causing this?

i have a similar problem where if i am on wifi, when i get off wifi my lte or h+ will show bars but have a small x in the bars. i have to cycle airplane mode to get data back after i switch wifi off. i may just make a tasker task to do this.
i had a call from an s9 yesterday where i could hear them but they couldnt hear me. i think i was on wifi. we tried 2-3 times but he couldnt hear me. when i switched to my google voice phone number and called him, he was able to hear me fine.
there is another thread around here about similar issues. i might try to get a new sim card since this one is almost 9 years old.

I may have started that original thread a while ago, but since it was more focused on the data drop thing I created a new thread to help narrow the conversation towards the wifi issue. I went to ATT when I first had the data drop issue and got a brand new sim so it is definitely not that.
