Network Problem with AT&T... Help with troubleshooting?

[zerogear]

So lately I've been having some issues with my HTC One M8 on ATT network. Randomly I've been unable to connect to specific services. The three main ones I've noticed is Google Search & Voice Search (through widget but not google.com), Spotify, and Pandora. During which, almost everything else I've tried have worked asides from those.

Now at first I thought it was adblocking messing with connection, but when on WiFi, everything works fine. I have even done a complete reset and didn't do titanium restore to start fresh. No go.

I'm almost positive that it isn't my device but that the ATT network in my area is the problem. Either that or they are actively throttling those services.

Anyone else have any ideas what might be the problem?

ipv6?

Not sure, on the ISP end or the service end? Though interestingly, if I switch it to HSDPA+, it will connect. But if I switch back to LTE, it will stop working.

Anyone around you on AT&T with a different phone (including M8 that isn't yours)?

Do you have a proxy listed under the APN?
ATT postpaid or MVNO?

i had the same issue with an HTC One M8 recently and fixed it. it was working fine on data, i don't move an inch, and then i pick it up to use it and then nothing, no data. happened in multiple apps. Google Maps would say try again, no network connection. a restart always fixed it.

it also started dropping phone calls often, and i rarely had dropped calls, and it dropped them in good signal areas. and it had 1 spot that for sure it ALWAYS dropped - driving by Giants Stadium in Northern NJ on my way home from work, which has excellent service. i noticed it 3 days in a row so then i made a conscious decision to be on the phone there each day. it happened every single time. figured it was an AT&T network issue, whether a tower handoff issue but cause of the other problems in other places, figured a general network issue on their end - called them to reprogram my phone on the network, they did. issues fixed now for a couple of weeks.

it wasn't throttling. i was always under 2gb of data which was my plan. call them up and have them fix you.

Thanks PixelSquish, I'll give that a try.
