CM11 M12 data issues - Verizon HTC One (M8)

Hi,
I flashed the new M12 release of CM earlier today, and it's a really, really solid rom. The problem is that I was only getting 3g data speeds (<2 mb/s) despite being in a good signal area and having the LTE indicator in the status bar. I never had this problem on M11.
Has anyone else had this issue? Any suggestions? I'd rather not go back to M11 because M12 is rock-solid and noticeably smoother.
Thanks!

[Q] Bad signal with CM9

When flashed CM9 wiresless signal got worse and looks like cell signal is also worse but I'm not sure about last one. Flashed latest radio, but it did not change anything. Does anybody else have this issue?

[Q] 3g not working after flashing cm10

Hey y'all,
I'm hoping I can get some help on this. I just flashed CM10 stable last night and everything seemed to be working fine before I went to bed. But when I was using my phone this morning, I noticed that i'm only etting data at EDGE speeds. It seems as though my 3G (or 3.5G) isn't working. I made sure my APN settings were correct but that didn't fix it.
Is this a known problem with CM10 stable on our phones?
If so, how do i fix it?
Thanks for the help guys.
I had CM10 stable in the recent days and I didn't have any problem with the HSDPA. Try to reflash the ROM step by step.. Or try to change the ROM with another and watch if the 3G connection works.

Slow data speeds

So, I flashed CM11 today, and I'm not sure if it's just this specific rom or what (I had poweruser modified stock before) and it seems like my data speeds are really slow.
I had 5 bars with H+ (yes not LTE I know) but I was only getting 1 mb/s down speed.
Is there a baseband I can flash or some type of modem. Does anyone else have this issue?

Well,
I'm sorry that I can't exactly help your situation, But I can say that I am having a very similar issue. I am running D800 AT&T, CloudyStock V2.0 with dr87's Simple Kernel V5. Only have one APN, which the the Phone APN. Now, I do receive LTE, it also shows up on my phone as 4G.
I have also changed that lil bit in the Build.prop to my destination Country, which is US. But, anyway, After all of this I can only get maybe 2mbps downloads and if i'm lucky I will pull 1mbps upload.
I know for a fact that the LTE in my town is not that slow. I'm not really sure what is going on either.
Before I had CloudyStock on my G2 I could get around 11-12mps downloads with 4-5mbps uploads.
Sorry that I can't really help you out OP. I need help as well.
Since you mentioned, I have an AT&T with a T-mobile micro sim and the network signal (not data) has been very poor since I got the phone. Usually just 2 or 3 bars and completely lost the signal when I got down to the subway underground. I noticed that people were still using their phones while on the train so they could actually receive signals. I believe it's something to do with the sim but not for sure. I haven't had a chance to borrow anyone else's sim to try on mine so I couldn't really tell. I'm running CM 11 as well and I think the battery life has been reduced because of the weak network signal
Any help?

[Q] anybody else having 4g connection issues?

About 3 weeks ago after installing the update of liquidsmooth 4.4.4 i randomly started dropping to 3g service in places that i normally had full 4g available. It has slowly gotten worse to where if im not on wifi, than the phone is pretty much useless. i normally have full coverage everywhere. so i originally thought that maybe something had gotten messed up on the update, so i did a clean install of liquidsmooth 4.4, and blackbird kernal and same thing still occurred. also tried carbon rom and slimrom, and no luck. so for the fun of it, i went ahead and reflashed the phone back to stock from backups and rerooted it, updated the modems and reinstalled liquidsmooth w/ blackbird kernal, and same thing. i have went through all the mobile networks settings and tried everything and nothing seems to help, idk if that update screwed something up or if its an issue that others have been experiencing as well, or if im just screwed and my phone phone is dying.... any help is appreciated thanks

I'm currently running OmniToad, and ran CM 11M8 for a short while. On T-Mobile at least, with the custom ROMs it's normal to see H+ only when data is being transferred; it will drop back to 3G otherwise. When I ran the stock ROM on the Relay, it would always say "4G" regardless of whether it was in UMTS (3G) or HSPA+ mode. Apps like SignalCheck or CellMapper will tell you which mode it is really in.
On the other hand, if data transmission is only going through as 3G, it could be a phone issue or a tower issue. Is LTE available in your area, or are they just getting it set up? I know when T-Mobile was upgrading the Chicago area to provide LTE, there were a few glitches here and there.
It was stupid for T-Mobile to brand HSPA+ as "4G" but that's a different rant.

yea LTE has been in this area for quite a while now, i had it with my S4 and it worked perfectly, i never had a problem with the service on the relay either up untill a few weeks ago the internet speed and and data coverage was great, not quite as fast as the LTE on my S4 but it was still more than adequate, i used to use the hotspot and stream netflix on my laptop. now i can usually get a text to send but calls usually fail and if i try and use the internet its impossible. it almost seems like its doing the exact opposite of what it should be doing, as soon as i try and use anything (not while connected to wifi) than it drops coverage to 3g/edge/ or to nothing at all. Im leaning towards the hardware failing side, but i figured i might as well give it a shot and post it and see if maybe i wasnt alone. thank you for your reply.
small note of background on me: first time posting ever in this forum but have been using the tools and roms from it for a long time, so im not a complete noob, but i definitely still have a lot to learn.

[CM 12] T-Mobile Connection Fluctuation

I just installed the latest CM12 nightly on my Nexus 5. The experience has been smooth for the most part, but my connection to T-Mobile's network has been pretty unreliable.
In places where I used to get LTE with stock Android 5.1, I now randomly switch between HSPA+ and 3G. I have a feeling that something is borked, but I don't know for sure. Any suggestions? Thanks.

There shouldn't be anything from the ROM side that messes with your connection. I would double check your APN settings and you can try flashing other radios to see if your connection gets better. Is T-Mobile doing any work in the area? In on T-Mobile and have had no such issues on any aosp based Roms. I'm not much for cm but haven't noticed anything while running them.
