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.

This thread is from December. You Gus are not going to get much help on an outdated thread. You will have better luck on a newer thread

Should of stayed with t-mobile.

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..
sent from my Evo

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.

[Q] *Is anyone having problems w/ 4G and flash sites?*

Peace All,
Has anyone been having problems w/ their 4G service wherein it hangs (on loading) a site that is heavily ladened w/ FLASH (not to be confused w/ the current Gtalk and market issues)? I've tried the plug-in selections of "ON DEMAND" and even "ALWAYS" and it seems that it takes my 4G almost 3 -4 minutes (if it even loads) just to download the site fully---my 3G is actually faster . I've ran speed tests and when i'm on 4G i"m pulling 4.63 mbps down and about 1.00 mbps up---I've even checked to see if my RSA keys were intact and they were. The people (customer service) seem oblivious to this problem. Is there a fix for this?
thanks in advance for anyone's insight to this problem
-ZDK-

I don't know, I'll check mine tomorrow when I'm in a 4g area.
Problem with customer service is, they don't have a clue with anything network related. All they do is check to see how many problems similar to what a person reports as a problem and then make a note of it.

No problems with flash on 4g.
FYI - I am running AVO v9 and Flash Fix 10 so I can watch Hulu, and it worked great.

Peace,
Well i guess I'm the only one---this has happened on every ROM I've tried (Ava9 and Myn's Rsl2)---I've called Sprint and I've ran various tests to check my 4G and my RSA keys are in tact and my MAC address is cool---I also have the latest radio, prl, pri and wimax versions---I'm going back to stock---theming and custom ROM's are too much of a hassle and not worth it (most people on here appear to be sooo OBSESSED about battery life that they turn off every function of the phone so that they can brag that they havent charged in 8 days ). I use my phone to the fullest and like running 4G--since im in a 4G saturated area---all day
Thanks anyway,
-ZDK-

use flash on demand, that speeds up all your site loadings, make the browser more stable, and removes ads, unless you like ads, .

For me flash site works perfect on 4G...

only issues i have on 4g are pc related, whether im tethered or using hotspot, if the 4g dips just a little the flash video stops loading, when i get to that part the players just hang at what ever the buffer says which is usually 45% to 51% and i have to refresh and jump to the place it stopped, the overall 4g connection is very stable, i have no clue whats going on
btw would you happen to be using dolphin browser hd?? there have been a lot of comments about browser slowdown with froyo and the site has a few suggestions to help speed it up

I've actually got the exact same problem as the OP. I recently did some modifications to the wimax settings so 4g would connect faster and stay connected longer and wonder if that may have something to do with it. Otherwise I do not know what might have changed.

MikFroyo 4.5 WiFi problems

I'm trying out the MikFroyo 4.5 ROM and was liking it until I noticed download speeds over WiFi. The throughput seems to be incredibly SLOW compared to my previous ROM (Rebirth-ACrom), which was blazing fast. Funny thing is, though, that the Speedtest app shows fast speeds. And yes, I did everything properly, including wiping data and cache before flashing the ROM and testing before restoring with Titanium. Is there a fix for this? Otherwise I might have to look at a different ROM, such as SPRINTLOVERS or Myn.
And for that matter, Market downloads over 4G seem to be a bit slow (closer to 3G speeds) as well.

my wifi is fine, no problems here, wipe data, wipe cache/dalvik and system. i dont like myn, heap size is too small
at one point my wifi got shot and killed and could not use it. but figured out it was a kernel issue, so try another kernel like the sbc kernel

Did you restore any system data with TB? If so, that may be the issue.

I'm having the same issue. I noticed my wifi has problems scanning for networks, throws an error "Unable to scan for networks" and then turns off the wifi.
I did do a TB and a restore with it, but I only restored the apps and data, not system files or data at all.

I had the same problems. I finally had to uninstall Mikfroyo 4.5 while I still had hair left. I think it had something to do with the addfree app. Open addfree and select revert then try using Titanium back up to clear all data and uninstall addfree. That might help. If I remember right the addfree app was installed with the ROM.
I never understood why my phone always ran so slow in every department while using what was supposed to be the fastest EVO rom so I finally just flashed something else. Currently using Myns Z rom and my wifi is blazing.

I was having the same problem, changed the kernel and solved the problem.

I'm currently experiencing the same issue where it's unable to scan networks. What kernel did you end up flashing to NiMiNuM?

Running Mikfroyo V4.5 Also with a No SBC MoreHavs Kernel and I am finally in a 4G area and connected to it with good signal, but when I go to use the hotspot setting it tells me that I am not subscribed to Hotspot service. Will let me hotspot 3G but as soon as I get 4G up and running it tells me that message, any ideas?

Unfortunately I did not notice the problem right away, but having the same prob. Interesting thing I recently (this weekend) tried a few(Virus,Misfit,MikGinger) of the new leaked sense gingerbread roms. I also switched kernels a few times, but have the same problem across the board. I did catch where something borked in the buildprob could cause this. I can still tether my laptop, just will not scan and therefore can't connect via wifi. Besides doing everything correctly I do nandroid backups before changes. Unfortunately i delete older ones (space issue). So my oldest nandroid is mikfroyo4.5 with the scanning issue. ANY IDEAS?

I found from upgrading to 4.61 that the problem was with the dalvik-cache chewing up the entire cache partition. Once dalvik-cache was moved back to the data partition, the problem resolved. And 4.61 still has decent app space.

I have been using MikFroyo 4.5 all this morning and haven't seen any speed problems. On the WMU campus I was clocking in at around 1.3MB/s (not mbps)

As I posted earlier I had the unable to scan problem. Once I gave in and did a complete wipe/data reset my problem was solved. If all else fails....

[Q] slow wifi and 3g speeds.

i see a ton of youtube vids testing wifi and 3g. seems mine is the slowest around and cant figure out why. if im on wifi or 3g i get 1500kbps. doesnt matter which i use. i get my full 18 mbps speeds if i test with my laptop but again not with this phone.
any clue as to what the hell?
running stock rooted rom.

Same here
Yeah, I'm getting the exact same thing. First had an issue where my wifi would be in a permanent cycle of scanning, connecting, disconnected. I found a post saying it was an issue with the wap_supplicant file and that forcing it back to an older version (which was pulled from an old CM 6 alpha build) would resolve it. Tried that, and now my wifi isn't cycling anymore (so that's fixed) and can actually connect to my wifi, but now my data speed goes to almost nothing after trying to do anything with data other than running a speed test.
EX: reboot phone
run speed test 3 times, each time giving 11 Mbps down and 786 Kbps up (which is what it should be at on the low end but I'm happy with it).
go to the market, search for an app (don't download anything), go to the web, do a google search
now data is slow
run speedtest 3 times, each time get approx 900 Kbps down and 786 Kbps up
reboot and the same thing just keeps happening again and again.
Stock ROM, rooted but nothing else (other than the older wap_supplicant).
If someone can find a solution to this that'd be great!
