HTC MyTouch 3G - Cyanogen ROM no longer has data connection

I've unlocked a T-Mobile MyTouch 3G (32B) for AT&T. I rooted my phone yesterday purely out of spirit for experimentation. I've installed CyanogenMod-4.2.8.1, found on the website. I'm trying to connect to the market, but no type of data connection is being made.
The unusual part is that I have full signal strength. E or G sometimes pops on, but then drops off. I've quadruple-checked the APN settings, and they're fine. However, I did notice at one point the password had been deleted. I am aware that my phone version is not able to get on 3G band (although I'd like to find a hardware mod~)
I'm almost certain it's the Cyanogen ROM simply because before rooting, I had no data problems. Seems even a WiFi connection won't give me data. I've searched the internet to see if anyone else has had this problem, but it doesn't seem so. Any ideas?
Disabled WiFi and I have data. Apparently the two don't get along well. Just noticed an update to the ROM, so we shall see what will happen!
Or, if anyone has any suggestions on an alternative ROM, I'm not looking for anything too fancy (the MyTouch is serving as pure novelty at the moment; HTC Fuze is my primary phone). Speed and battery optimizations are most prefered, bluetooth/USB tethering a plus, and if it runs aHome or Home++ without a hitch, I'd be content.

I just upgraded to CM 4.2.9.1 on my MT3G 32B and am having data issues. Could it be a coincidence? Could it be T-Mobile upgrading to HPSA? Or could it be CM?

It's possible to be the ROM, as I'm on the AT&T network. I'll give the updated ROM a test as soon as I get some time to it.

Try reflashing radio. http://developer.htc.com/google-io-device.html

Works fine on my 32B Magic. Tried running fix_permissions, wiping and reflashing?

Got the same problem on my G1 with 4.2.9.1
When Wifi is active, after about 10 minutes i have no data connection anymore.
If i disable wifi i don't get this problem

i too have had this problem on my three magic 32a. i rebooted this morning and it went back to normal though. have only seen it once so i can't really comment on the cause. typically i have wifi always on and location by networks off...

How did you install CM?
Did you install the HTC 1.6 rooted base first, then the CM image after without re-booting?
You have to the first time you install CM. You don't say whether you did or didn't.

Did you remember to configure the APN correctly???

maybe related to instal issue?
I have the same issue but did "install the HTC 1.6 rooted base first, then the CM image after without re-booting". However upon booting into Cyanogen, I couldn't get past the "touch the android" screen and thus had to boot back into recovery mode and clear all data. After reboot I was able to pass the touch the android screen, but perhaps that wiped the 1.6 base settings?
Do I need to re-install, what if i have the same problem with getting past touching the android again?
I haven't tried updating the radio, but will try that first.

mobile network data
Found it: looks like toggle for mobile network data is turning it self off. Other than to conserve battery / airplane mode is there ever a reason to have it off? (is it bad to have on with WiFi?)
thanks.

Radio from Official Froyo OTA

I noticed that the new radio ruins my reception.
Places where i had moderate reception went to zilch.
My 3G speeds are atrocious when it works, other times it just disconnects and only comes back on when i toggle the mobile internet on and off.
Anyone else notice these issues? I was browsing around and I think this was a problem for when the Desire updated also.
I don't know whether to direct my anger at google or htc. how did they manage to make things on a whole worse with an update.

Mine did the Same with the the Leaked RUU update to install the official .6 update.
After it installed i logged in like normal and saw it was acting up. So i did a factory reset and it's worked great ever since

I've done the factory reset and I'm still getting horrible connection speeds where I used to get usable speeds.

Try update profile.. not sure if that will help..

Unfortunately that did not work. I'm on the latest PRL and everything, can't figure what it could be other than the network. Although it's not unlike the problem I was having with my PC recently after getting a new router, download speeds were almost nonexistent while uploads were fine. I just ran speedtest again and I got 7kbps down/>200kbps up. For my PC I had to get a new network adapter. Don't know how I could do that for my Evo.

Data issues w/ CM6.1 RC2 + updated radio

Hey everyone. I've been having issues with my data connection and I'm trying to figure out what is causing it. I am using CM 6.1 RC2 and I have the updated radio from the vodafone rom.
For example, when I enter the market, about 50% of the time I get a network error after resuming from sleep and have to click retry once or twice before I can do anything. The data connection is just not reliable anymore (yet before this issue it always was).
I'm just wondering if there is an issue with RC2 of CM or if it is the radio update causing this. Can anyone comment?

I'm not sure this would be related, but after flashing 6.1.0 on my Dream I find it stuck in EDGE occasionally, usually when in the car or after, and in places where I get solid HSPA before 6.1.0. So far, I have to reboot to get HSPA (or 3G) back. There are some notes on updated radio and a kernel to address some radio problems, is anyone else seeing this?

Hi,
I have similar problem. My legend is not with the latest radio or kernel.
The specs are:
CyanogenMod Legend 6.1
Radio: 7.05.35.26
Kernel: 2.6.29.6
The problem that I see is: During the night when the phone is not used it looses the data connection. When I turn it on in the morning there are no mobile network indicators. I have to reset the network ( by airplane mode or reboot) ot get back my data connection.
During the day there are no problems.
I suspect that this happens because of the weak 3G signal in my area. However I use auto setting. ( 2G and 3G)
When I was with stock ROM I haven't such issues with dead data connection during long sleep.
EDIT: I have just upgraded the radio to 7.08.35.21. I will check how it works tonight.
BR

I'm having similar trouble with CM 6.1 released just a few days ago...
I've posted this to Cyanogen Stable Forum for Legend:
h t t p ://forum.cyanogenmod.com/topic/11966-cyanogen-61-htc-legend-problems-with-3g-connection/
I think I've similar problem as you...

I have updated the radio to 7.08.35.21.
This morning when I woke up I saw no data connection again The signal strength indicator was full with bars!
Anyone has any clue?

I've been having some data issues too, I've had to go to and from Flight Mode in order to get any form of connection (data OR telephone) back, and I occasionally get stuck on GPRS. Toggling "use only 2G networks", waiting for the data to come back and then toggling it off again gets EDGE or H back, but it's pretty flaky compared to RC1 and the older radio.

I think i have the same or similar problem.
It looks like I have a data connection (3g is showing and signal strength is almost full). But when i try to connect to facebook, browser or somthing else what needs a connection it cant connect.
I have a taskkiller running when i kill all the task 90% of the time i will get a connection.
I have the same programs on my phone when i used 2.1 and with 2.1 I never had this problem.

Strangely enough it seems like mine is working much better lately. Maybe there was something up with Bell. I haven't gotten the connection error in days.

After update to radio 7.13.35.05 I haven't had this sissue again.
I will continue to watch he behavior.

[Solved] Cyanogen Wifi connectivity issues (all models)

After flashing CM6.1 I got the notorious wifi connectivity issue that numerous people have been reporting around the web. The issue is the following:
1: Wifi discovers neighbor's AP but no longer home AP.
2: Wifi problem randomly fixes itself, but sometime comes back and home AP can't be found again.
Many random solutions on the web include removing all stored AP's on the phone, resetting the router, rebooting and power cycling the phone numerous times, etc. Most people report that wifi miraculously start working again after the above but there is no consistency to exactly why and what works.
I tried all of the above with no luck, and even flashed three different roms with different kernels, did wipes, formatted everything inculding boot partition etc.
Here is the ACTUAL problem:
Different regions use different wifi channels. North America uses the first 11, most of the world uses 13, and Japan uses all 14. After flashing CM6.1 it changed the regulatory domain on the phone to only scan the first 11 channels meaning my European router broadcasting on 13 wouldn't show up. This setting seems to be persistent and doesn't change just because a new rom is flashed.
The reason people report the problem to be randomly fixed after a few days (and sometimes coming back days later) is because most routers automatically select which channel to broadcast on and therefore might end up within the first 11 at occasion. If it changes to something higher after that however, the problem is back.
Solution:
Open Settings, Wireless & network settings, Wi-Fi settings. Press "Menu" and select Advanced. Press regulatory domain and change to 14 channels.
To learn more about this and understand which channels are used in which countries, look here: http://en.wikipedia.org/wiki/List_of_WLAN_channels#2.4.C2.A0GHz_.28802.11b.2Fg.2Fn.29

Thanks man, even I still met an issue which was wifi disconnect frequently (usually after 12 seconds or less, it's re-scanning AP and trying to re-connect again) when I was trying to share my broadband internet from laptop to my legend.
BUT, after I update my wlan driver (now using 8.0.0.238 for my Atheros AR5XXX), the issue seems gone.
I found that by updating wlan driver to the very latest driver (for mine is 9.2.0.xxx) is not a guarantee to resolve this problem.
Now, by combining your suggestion and an "appropriate" driver version for my wlan, it work flawlessly until now
PS: driver version which will work varies from devices to devices. Do trial and error if you must
edit: well, not 100% gone, but much better . the connection is far more stable

Could be a problem for some but not all the issues with WiFi. I knew about this and even posted one or two times this check for the number of channels in different other topics as a possible solution. Still there are times when the connection to the "home" AP is done very late after entering in range or switching on the WiFi and the signal is changing from none to full and back frequently, for the same relative position to the router (I'm standing in the same place). Also even if the signal is full or good, the Legend seems not to have Internet connection that is, the weather updates or XDA applications or browser could not connect. This is still happening even if the selection for the number of channels is correct. And also this is not happening with a stock ROM, I made some comparisons between my Legend and one of my friends that has stock ROM. He is having full signal and excellent browsing experience while I have random disconnects or drops in signal level. My thought is that the difference between drivers made by HTC and the ones in CM ROM is the cause. As it is with some other HTC proprietary developments (like Flash implementation or FM radio), could be that HTC spent some more development time in eliminating bugs and making a better driver.
Of course, this will not stop me use CM ROMS, it is a little bit frustrating, but the other things in CM ROM's makes the difference for me.

I think you're right. Yesterday, I tried my friend's phone (which has a stock ROM), using the same AP and there was no dropped signal or disconnected in wifi. I also tried using other android phone brand (5 series from samsung) which also has a stock ROM and there was no problem at all. Drivers is the culprit

Work
Thanks u very much.worked on my milestone

Thanks. Actually worked.

Hello Rapier,
I have installed the CyanogenMod 6.1.1 (stable) on my HTC Desire (GSM / France) with latest radio image (32.49.00.32U_5.11.05.27) and taken some time to configure it. Now, everything seems to run well ... excepted the WiFi (and perhaps also the GSM). My problem is exactlw what you have described:
- on stock ROMs, the WiFi signal is stable and quite strong
- on Cyanogen ROM 6.1.1, the WiFi signal fluctuates, the connection is unstable and gets lost.
I like CyanogenMod ROMs very much. The WiFi issue is the only thing that I was not able to correct. You were speaking about WiFi drivers: would it be possible to extract the WiFi drivers from the latest HTC Desire stock ROM and copy them into the CyanogenMod installation?
My impression is that the CyanogenROM is scanning for networks in the background, even if a stable and strong WiFi network has been found and is currently connected. Perhaps there is a possibility to disable this scanning?
To finish, I have also the impression (I know, this is not very scientific ... but perhaps it could help to determinate where the issue comes from) that the GSM network is also fluctuating. I use WiFi Analyzer (available on the Android market) and when I plot a graph, without moving the phone or even without moving myself, the plot oscillates between -80dBm and -30dBm (I swear that there is nobody playing with the on/off button of my ZyXEL router ).
@sz1a: Thank you very much for your post: this helped me to discover these "hidden" settings, but my configuration is manual on the ZyXEL and everything was fine. Perhaps you should switch the thread to "unsolved".

I'n not a developer, only an ethusiast with a Legend. Also I'm not a Linux expert so I can only guess and experiment...threfore I cannot tell if porting HTC proprietary drivers is possible. I'd say not...if it was, we would have it by now. The main reason I think, is that those drivers are not open source, so nobody can port them since the sources are not available. I'm sure that if it was possible, they'll have been included in CM

[Q] Connection issues

Ok so I have been searching for an answer to my issue for a few days but have had no luck. My wife and I both have an evo that we got at the same time. I rooted both using the same method and and we both have the cm7 Tom with the kernel it comes with.
For the past week she has been having connection issues. Sometimes when accessing the android market it says network connection error and other times it works fine. When accessing the internet it will sometimes not load the page and say that the site may be down. The has been happening a lot to her lately. When these things happen I try the same sites on my phone and they work fine. This is all done over a 3g connection. I have tried resetting the phone to factory and then redoing the rom and nothing helps.
Any suggestions?

I'm having the same issues as well. I've flashed a few different roms and my radios are up to date.

I had similar issues and found that by tweaking the Pri, Prl, and radio...can be found in dev section, that I was able to overcome... could just be a bad combo with that rom

VyperVainz, do you mind sharing what worked for you? I'm running synergy with the latest pri, nv and radio.

I think this is a network issue. My wife and I have been having both data and texting issues. She has a blackberry so not Evo isolated.

Sprint's network has been pretty crappy lately. Slow speeds dropped loading pages, I don't think it's a rom issue

It's an internet, non phone issue. :-D I often go betwen wifi and the normal connection to get a connection to the market.
