MyTouch 3G Slide Wifi Problems w/ CM7

---

Alright I have a Mytouch 3G Slide and I have been having wifi issues after a few weeks of using cm7.0.3. It started to not be able to turn on the wifi and the status would say "connecting.." then it would fail and stay at "disconnected". All my networks would say "Not In Range". I tried to remove and re-add my network but my wifi would not even be able to search for networks since it could not turn on. I tried to update my radio to a newer one I found on XDA (posted in march or april) that was for Froyo 2.2 (my current radio had been the one i was using since i first rooted my phone to cm6), and the new radio I flashed didn't fix anything either. I tried reverting to CM6.1.1. but it would not boot; after It turned on, the Tmobile screen would come up, then a custom splash screen would keep looping (the video would keep looping, normal, but i let it on for about 30-45 minutes and it would still not boot). I don't know why it wouldn't boot up, the only explanation I could think of is my new radio but other than that I don't know..

I would really like my wifi to work on cm7 because I don't have a data plan, but if not, I would atleast be able to run cm6 (where wifi was never an issue for me). Please help!

hey dude had the same problem, and i am not a dev in any way but i think a file within the /system directory is missing or something like that so your best bet is to [unfortunately] install a diffrent rom w/ wifi support, and then flash BACK to CM7.0.3 (not from backup, but from scratch) really hope this helps u man

yo. i had the same problem as you. there's a fix somewhere on the forums about fixing the wifi on cm6. I haven't tried it yet, but i'm thinking of flashing back to cm7, applying the "fix" and see if that has any imporvements

here is the fix

I've had similar problems with 7.0.0 RC2. At some point or other, the WiFi just stops working. Can't turn on. Reads as "Connecting...", then gives up and drops to "Disconnected"

The only thing that's made it come back so far is restoring a backup ROM from the ROM Manager, but I hate doing that since I keep having to replay the levels of Angry Birds I've already beat.

Haven't tried doing things like flushing the caches from the boot interface, I'll try that next time it breaks.

Try titanium backup - you should be able to back up the app and the data. Or, there are apps in the market that specifically back up Angry Birds data.

As for me, I've never had wifi problems with CM7. Although it could be I don't use the wifi that much or maybe because I had updated the radio and stuff and had a rooted version of the ota (before the actual update) and then I installed CM6 and then made the jump to CM7.

so all in all there is no real concrete answer to solving the CM7 wifi problem without having to flash an old ROM and then get back to CM?

The link that "the1hand3r" provided seems a bit complex for a problem that the developers could easily fix in anyone of the daily updates.

I could be wrong (and I'd be interested to hear what the above poster found out when replacing those modules from CM6) but CM6 and CM7 use different versions of the Linux kernel.

Those driver modules are compiled to work with a particular version of the kernel and most likely will not work with CM7. If it were that easy, as said above, I imagine someone would have included them in the nightlies by now.

They're probably part of the Slide codebase that hasn't been released as open source. Because of that, ROM devs wouldn't be able to modify or improve on what we already have, unless a newer phone with the same radio chip comes out with updated drivers that can be dropped in to a Slide ROM.

its an easy fix duuudes. download cm6.1.1 final and the latest cm7. open up both in a zip program and in something like sys/etc/wifi you'll find a file called twlan.ini. take that file from cm6 and use it to replace the one in cm7. (same directory) voila!

Can anyone confirm what neoslink1 is true? I'd like to know before I wreck my phone any further.

By the way, does anyone know if the 3G/4G still works if the wifi doesn't?

The 3G still works, at least on mine. My wi-fi quit yesterday, after months of running with no problems. I had not done any updating of the ROM, hadn't changed any operational files. I've enjoyed running CM7, but can't have my wi-fi stop working for no reason.
