Losing data connection on CM7

I have been keeping up with the updates hopeing each one will fix my problem but not yet. I don't see others with the issue.
I'm running the latest Test4(Test3) using Slayhers stock kernel. Everything works awesome except intermittently I lose connection whether I'm using Wifi or 3G(No 4G in my area). The only way I've found to get it back is reboot.
Is this a widespread issue or just me?

Same issue here. I live in 4G area. Intermintent Data Loss. If i switch to CDMA i get a 3G but CDMA/LTE i get nothing. I had data allday yesterday but none today.

I think the RIL is still being worked out. Bear in mind that this is a Pre Alpha Pre release. Also LTE is something completely new to the world of CM and to American cell phones. I've run CM on 3 different devices and I will tell you that by the time nightlies roll around, it will be near perfect. The CM team won't put their name behind something that is half working, half assed, etc. Be patient.

I had the same problem but now I have a small problem. I have a very fast wifi setup at home but it doesn't like to actually connect to it. Looks like 3G is riding shotgun for a while.

One thing I read about the WIFI is, try turning the WIFI on then reboot with the WIFI on to see if you then connect.

Yeah, I think we'll all be experiencing this until the crew addresses it in a future update. However, it is still a great start. Not a whole lot of major issues, no deal breakers. I'm still using it as my DD.

Definately!!! I love the cm7 build and I'm thankful for all the work. Just wasn't sure if there was an easy fix I had missed.
Thanks all!

[Q] Google connection sync/talk on NS never stays on consistently, lately.

Device: NEXUS S
Carrier: TMOBILE
Country / Language: USA
OS / Browser / build number (if applicable): 2.3.4
As of about two weeks now, my Google services connection sync and even Gtalk never stay on consistently. Data icon goes from green to gray, after wakeup. hen when it is green, I only then start to receive me push notifications. I never had this problem before and was very happy with the Nexus S. Now, however, I'm not so sure about that anymore, and it's a consensus out there that there is no solution, and that Google is "looking" into the problem. I don't think it's necessarily a hardware issue as everything was fine out of the box when I first got my phone, so its likely a Google server problem? Though it sounds like the problems are isolated to Nexus devices and myTouch 4G phones.
I would call Samsung to try to get a replacement device, but from what I hear, it doesn't solve the problem either, and Samsung's CS really sucks too.
Any advice would be greatly appreciated.

I am going through the same trouble, too. I think its more of Google server related. One thing tthat I am sure is, it started very recently. About 3 weeks ago.

I have the same issue. It started a few weeks back. Got the 2.3.4 ota...same issue. Came from 2.3.2.

It's been happening to me for a while as well. Even back in 2.3.3 when I was on CM7 and OEM. I seriously think it's a problem on Google's side and they really need to address it because it keeps logging me off of Gtalk which is annoying.

Funny thing is. I notice that it happens alot less when I'm using 2g only....
Wonder if there is something to that..

I am also on two google threads about this, and there is still no agreement on a solution..

I am having the same problem since around mid April. This is so frustrating, please guys flood the google help forums, this the only way google will see the seriousness of the problem.

Flood indeed. Google is clueless on a solution to this problem, especially if they don't even acknowledge it..

Yeah I stay green if I'm on 3g, so maybe it's a wifi issue. I would've sworn it was a 2.3.4 issue though.

highly doubtful that this is a wifi issue, with the number of people of various threads stating that they dont even use wifi....worse yet it occurs regardless of wifi or 3g/2g
i posted a video on youtube showing the problem

i have the same issue, both of my nexus 1 and tmo G2

[Q] Connectivity problem, all roms?

Been using custom roms on my Inspire 4g since about March with no serious issues till this week. Sometime around wednesday, my connection to my google account, the connection to talk, market, gmail, etc. Seems to be dropping out and locking up my 4g connection for a minute or two. This is really annoying. I have tried numerous different radio and rom combinations as well as going to the store and getting a new phone. The only thing that keeps it up and running is if I roll back to stock. Any help would be greatly appreciated.
Have recently tested Absolution, CM7, Android Revolution, and TalonRom with recommended radios per developer instruction to no avail. But am up and running fine with roll back to att gingerbread update via hack kit...
Any suggestions?

I was experiencing loss of background data on both my inspire and my atrix with stock gingerbread, until just recently. The only conclusion I came to was that ATT had a problem, at least in my area, with background data staying connected on 4G phones running gingerbread, except on wifi. About a week and a half ago, I noticed that the problem had mysteriously resolved itself, and I was having no more issues with push to email and other apps. I can only assume it was something they fixed with a network solution. Perhaps this fix has caused a problem with the roms you're using. I know that numerous calls to customer service failed to produce an answer for my issues, it seemed either no one could figure it out, or it was a known issue that they weren't acknowledging.

Yes, similar to me. Thanks for the reply. I'll give a Rom a try over the weekend and see if the problem has rectified itself.

Data connection issues.

Hi. I was using my Sensation last night, went to bed and woke up the next day only to find that my 4G connection wasn't working! The signal bars were white and the icon (currently an H) is flashing. What does this mean? How can I fix it? I can only use Wifi at the moment, and I DO NOT pay an extra $10/mo to deal with this! How can I fix this? I've checked my data settings, rebooted my phone, scanned fir viruses, but can't figure it out!

They are referring to the number you call for T-Mobile US costumer service.

this happened to me the other day, even in 3G/4G mode my data would never connect and E would just keep flashing over and over again (in like 10 sec. intervals) thought it was a ROM problem so I restored a backup and sure enough, the problem was still happening. I could still make calls and send texts fine tho. its not happening to me anymore, but I found it weird. could it possibly be T-Mobile messing with their towers or something in preparation for LTE?

Well, I'm not sure what caused this very same issue for me a couple days ago. I can say that it ONLY effected my AOSP (CM9) rom, but my Sense rom was unphased. It seems to be a common recent complaint in the OpenSensation thread...
I've since then done a fresh install of CM9 RC1 with the addition of Tamcore's kernel. Although I'm not experiencing the described symptom any longer, I can say that my data speeds are far from exceptional. I'm not sure what is going on, but it does seem to be carrier related.

I experienced the same 1 day after flashing CM9 RC1. I re-flashed the Virtuous Inq. ROM I was using previously and the problem went away

My phone went back to normal later on. I think you were right mulletcutter, they might have been servicing it.

Same data connectivity issue
I have two sensations, both shows similar data connectivity issue on TMobile. Data signal jump to connected and not connected for couple hours, and eventually problem will go away. I have both phones rooted running either CM9 or Kang. So far I have tried couple following things but no solutions. I believe its HTC Sensation hardware issue:
1. Flickering so far seen usually after night long charge in the morning. It will last couple hours, some time days.
2. Changing/reflashing ROMs did not help at all and saw same issue continued.
3. One of my friend has Sensation and he also has seen same issue.
4. Some time going into Phone application(Dialer) and then Settings/Advance settings and come back without doing anything helps but not always.
Please post here is you have temporary/permanent solution or even know the root cause of this data connectivity issue.
Also thinking to call Tmobile to get some kind of help but not expecting much as I bought phones more than year ago but less than 2 years. I don't want to give any more commitment/agreement with Tmobile as planning to move to value plans to save some money. If Tmobile does not help, thinking to try American Express to conver it under extentended warranty as I paid by AMEX credit card.
Thanks

Have you tried the application get ril? I was having some issues myself, I'm also T-Mobile. I tried get ril and found out my radio and ril we're not matching. The application suggested a ril for download and once I did that I went from one bar of connection to five bars of connection on H. It made a big difference for me. Perhaps it could also help you? You can download get ril from the market. It sure won't hurt to try. Best of luck.

Its a defect in the basic aosp framework. There is nothing you can do to fix it. There is also nothing your usage did to start it.
The good news is that it should disappear on its on after a few hours.
Check my threads started history. You will find a thread near the top of that list showing almost all there is to know about this issue. I think my thread might be linked in the first 2 posts of the cm10 faq thread too.

Anybody still having data issues?

I've been using my Rogers HOX ever since it came out but always had random data drops. Tried all kinds of radios (with or without RIL) and all kinds of roms and the issue is still there. Losing data is not the biggest issue but it also drops the battery real quick because it keeps trying to connect.
Anybody ever find a solution to this?

I'm using the HOX on Straight Talk and lately I have noticed that when I have WiFi on for a while, assuming it stays connected, I lose mobile data. The only thing that bring it back is toggling airplane mode or rebooting the phone.
I am on Jellybean, and I am not sure if the issue was present in the stock ROM's.

Yep still having the same problem on AT&T with every combination of Kernel/ROM/Radio you can think of. I can also say that it isn't a "rooted only" problem because a coworker is having the same issues on 100% stock software. There's always that ONE THING that keeps my phone experiences from being perfect. Grrrrrrrr........

My rooted One X is doing the same thing. I can't wait for the Galaxy Note 2 to come out. HTC just can't quite seem to figure it out.

Stock 2.20 on Straight Talk. Have to toggle Airplane occasionally. Especially in North Little Rock. ::shrugs::

OP, have you restored your stock setup to see if the issue persists? Basic question, but for the sake of a starting point.

After so long, finaly found the problem. I don't know if it'll be the same for everyone but the problem was Swiftkey keyboard. The moment I uninstalled it, the problem did not reoccur.

I have the same problem and I can assure you its not the phone, I have used many android phones, iPhones, and regular phones on rogers 3G network and they all have the data drops in general like dropping to 1 bar and no service once and while.
You might want to switch your network to wcdma/gsm instead of wcdma/gsm/LTE. If you dont have the correct APN for the rogers lte network it will keep searching for the lte nrtwork causing the data drop. As soon as I turned my lte toggle off the network stopped dropping randomly though I still get those random data drops caused by the network

We had this issue with the rezound, it actually occurred because you flashed different radios.
You had to flash a ruu or a modified one without the system image. See my SIG
So try flashing a ruu, this doesn't explain someone with a stock phone having issues but I bet that's just tower issues
I don't have any of these issues

Tried all of the listed solutions and nothing worked. I know it's not the network because I don't have the problem with my Note II. Swiftkey was the issue for me, once removed, the issue never reoccurred.

Wow, you might be onto something here. I just installed SwiftKey last night and immediately started having issues. Data has been off-and-on with different versions of different ROMs, and never suspected that my issues may lie within an app that I was using. I was mucking about with radio ROMs and a million other settings, never realizing that SwiftKey was installed right around the time I started having issues on each ROM.
I'm going to jump back to CM10 this evening and see if this was my issue.
THANK YOU in advance! (Thanks button has been hit!) Nice work!

You gotta be sh***ing me! After all this time scouring xda and numerous other sites.starting my own tread it was SwiftKey all along? Wtf? I did a thousand different things. Nothing worked, took off Swiftkey, bam, flawless. I've got a T-mobile GS3 incase anyway was wondering, no, apparently it's not just with htc or AT&T/Rodgers. Weird though cuz my wife has a AT&T GS3 with Swiftkey and has no issues whatsoever... Did you dl your version from the playstore or from a 3rd party? Thanks a million for posting your solution. This was absolutely killing me. God do I hate this stock keyboard though...
