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.

Hey Guys,
Just wanted to know if anyone had any success flashing some Tmobile radios on their Skyrocket with a Jellybean ROM?
I am currently running AOKP JB Rom, and I have a Tmobile signal, I can make calls and text, but something seems to be blocking my data. APN settings show T-Mobile US, so I know there is a connection.
My current Baseband is: T989UVLH1 <----Is that the problem?
Thanks in advance.
I'm running R4INS AOKP Oct 24 build. Unfortunately I can't seem to get hspa working correctly no matter what radio I flash. I'm going to try a few other ones and report back. I get edge without a problem, but it has issues with H+. I get widely fluctuating strength and terrible down speeds (5kbps). The upload speed is better (300kbps) but not what I should be seeing in my area.

I just thought I would shed some light on an issue I've had since leaked jb Verizon modems came around. I am the owner of a vzw network extender. Whenever I am running any asop ROM, when I connect to the extender, my gs3 says I'm roaming. From cm10/10.1 to aokp to eclipse jb, This happens on every asop ROM I've tried. The only fix is to run an ICS modem. Also I have no issues using the k3 baseband with any tw based roms. I believe this has to do with the way the jb modems report being connected to the extender on a tw based rom. With the jb modem, the tw based roms tell you that you are connected to the extender. It says network extender in place of Verizon wireless on the pulldown and also the signal bars have a little home above it. This was new to jb. On an asop ROM I get roaming and an r in place of the home on the signal bars. Is it possible that asop ROMs have not caught up yet, being that not too many people have a signal extender? And feedback would be greatly appreciated.
I haven't been hearing about this issue as not many people have network extenders. I don't think any of the AOSP ROM developers have been working on a fix for it. Thank you for bringing it up in the mean time to take full advantage of your network extender you will have to use the Touchwiz roms.
Thanks for the reply. Is there any better way to get the word out to aosp ROM developers about this issue?
Other than the development thread and PM that is it.
Bringing this back, any fix for this problem yet? =/
Same problem
I am having the same problem running a Galaxy S4 with CM 10.1. I own a Network Extender at my business, and my phone shows the "R" over the bars and out of network in the detail area. In fact, I can not send Text Messages When the extender is on, even though I am connected through our company WIFI as well. What is the best way to change your modem, Odin? If so, where do you download the old modem software? Thanks!
TW Roms
I have only been using TW based roms because of this issue. I thank you all for posting this information here about the network extender issue. The good news is that all TWQ roms I have tried so far are working for my Network Extender except for Jedi so far on the Verizon network.
I have a rooted Samsung Galaxy S3 on Verizon's Network .I"m on a Verizon network extender at home and everytime I've installed any AOSP ROMs (Cyonogen Mod,Paranoid Android,Carbon ,Pacman etc,) my phone goes into roaming ,so I don't have a data connection or a phone connection, in my home with any of these ROM's. Outside of the network extender, the ROM's work. Currently I"m running Touchwiz Rom Jellybeans version 19. Stock or any Touchwiz ROM's work when I"m on the network extender. I've searched for a solution and have found none. I have owned my Galaxy S3 for over a year and haven't been able to run any of these ROM's because of the network extender issues. It's been very frustrating ,can someone please help with the situation?

I have to use a network extender at home as well. It's an older version so it doesn't handle data. I've used it on both TW and AOSP Roms without a problem, so what you have should work.
On AOSP roms, do you get the two tone note when you try to call? You should only need to dial #48 to register with it and then call out.

There are two different network extender models. On the older one, there is no data connection. The newer one offers 3G as well as voice I believe. So if you're on the older model you won't have network data and will have to rely on wifi. When you dial out, if you hear 2 tones before it begins to ring, then you're operating off the extender.
As long as you're on a stable version of a ROM, it shouldn't have any significant impact. I've used several TW and AOSP roms without noticing any real difference.

Hi, thank you for responding ,I appreciate you taking the time to answer. I've checked with Verizon and I"m on the newer network extender .On stock or Touchwiz ROM"s I do get a phone connection and 3G. I also get the the two tones when I dial a number before it connects. From what was explained to me that means I"m under the network extender. When I dial # 48 on an AOSP or TW ROM, it tells me that I'm under the network extender's connection.
95% of the ROM's I've used have been stable. The others have been Cyonogen Mod nightly's . On my Droid Razor Maxx,when running and AOSP ROM, I never had these issues.

In CM under
Settings > Wireless & Networks > More > Mobile networks
Do you have the data roaming options selected?
No, I've gone into mobile networks and changed it manually, rebooted and the "R" for roaming as shown in the photos is still there. I've manually forced it into 3g only and it remains the same. No data connection

Update: Currently I am running an AOSP Rom (CM 10.2 09-19-2013) and it's working. To get it to work, I installed the last ICS OTA modem (the VRLHE) and I am now getting data at home under the network extender. No more "R" for roaming! The modem is not as strong as the Jelly Bean VRBMF1 modem, but it's working. I still can't get any AOSP roms to work on JB modems and I don't know why. I was thinking of contacting the CM team for a possible solution. I am still glad it's working even though it's on an old radio.
I had the same issue two days ago when I flashed to the latest MIUI Rom. Here's how I fixed it.
Go into settings, mobile networks, make sure subscription is set to SIM. After that open the phone, type *#*#4636#*#* make sure it's set to LTE/CDMA/AUTO
Reboot phone and all should be well.

ok, so those with verizon network extenders, are you having issues connecting? I actually am, and want to make sure its not my phone.
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.
Using Ting (MVNO using Sprint network CDMA) ever since I upgraded from CM11 to CM12 I get intermittent loss of cell signal at times. Every couple of minutes, regardless of where I am or how strong my signal is I will lose all cellular signal for about 20 seconds, including voice and data, and then it will pop back up just like it was before.
I've tried downgrading to two different radios and nothing seems to make any difference. Like I said before this problem didn't occur until I did a clean flash of CM12.. everything was fine with CM11.
I've even wiped/reinstalled CM12 with the same issues.
Does anyone have a solution for this yet?
I recommend keeping your radios updated to LRX22C. Where did you get your ROM from?

From what I've gathered, it seems that sprint networks being unreliable on cm12 has been an existing problem that may get fixed in the future.

Well I fixed it.. sort of. I had tried this before but I didn't reboot the phone.
SETTINGS / MOBILE NETWORK SETTINGS/ PREFERRED NETWORK TYPE
I switched it from LTE to 3G. Looks like I might not be getting LTE coverage but it's hard to tell as LTE is sketchy at best at home and at work... and in either case I'm on Wi-fi anyway. Not a huge deal.
I had tried this before but I didn't reboot the phone after making the change. As long as I leave it on 3G my cell signal never drops. If I switch it to LTE or GLOBAL then it will randomly drop as described above.
I'll retest things after each CM12 update I install see if we get one that works!

Were you able to find a solution for this that you could share?
Honestly no..I just keep it on 3G and there are no issues.
I tried about a week ago switching back to LTE but the display never showed LTE and I definitely wasn't getting LTE speeds and the signal drop returned.
TBH LTE coverage is pretty spotty in my area and I don't use a lot of data outside of Wi-Fi anyway so it's pretty much a non issue for me.
When a CM12 snapshot is released I'll probably try again.
I should add that I dirty flash the latest nightly almost every morning. When a snapshot comes out I'll wipe and clean flash things and go from there.
Update... about a month ago I did a full wipe, going back to stock, did the network updates, etc and all was well.
Then I did a fresh install of cm12.1 and every thing worked great.. Lte and all!
A couple days later I dirty flashed a nightly and got an exclamation point and no data (Wi-Fi is fine). I did find the sprint fix flash which allows me to do the network updates again from cm (had to switch to 1X for it to work) but that only yielded a temporary fix.
I did however find a workaround. If I go to my apn settings menu and change a setting on my ting (sprint mvno I use) entry then change it back and save then BINGO! I have Lte again...
That is... Until I get handed off to another tower.. Then I have to do the workaround again.
