yes i've unplugged and reset my router. still no luck
K, one variable out the door, assuming you have other devices connecting to it no problem? Have you tried to connect wirelessly to another router? List what the router and modem you are using as someone with this more experience might help with more specific details. The other thing it it might have messed up hardware...

This happened to me once...and I had to have my g2x replaced...one thing I would try is http://forum.xda-developers.com/showthread.php?p=17258229
...if that still doesn't work...I'm with mt3g...it's probably hardware related...
EDIT: When I saw Error it never showed me the MAC address...do you see yours?

no. no mac address :C
If you have a Nandroid backup from BEFORE the issue started...I would try that...otherwise try the link from my previous post...

no didnt work tried the nvflash and now im at stock. but still no wifi -sigh- how would isend it back? and is it expensive?
this is either hardware, or more likely you are in need of a full factory reset
Sent from my Xoom using Tapatalk 2
whats a full factory reset 0.o?
well i got it to work after countless rebootings but... then i rebooted it to backup and when i started up again... no wifi and the backup has no wifi either =( nothings working for it

No sim card

Edit: NEW QUESTION
I DIDN'T MAKE A NEW POST THIS IS JUST AN OLD POST
9/19:
i was using my p500 during the day. works. i switch it off for a few hours. then i switch it back on. it says cannot detect sim card. I tried many different roms same thing. I verified that i do have v20g baseband installed and I have reinstalled baseband too.
I swear it was working several hours ago... I tried everything i could think of(except kdz... don't want to go there)
this happened while i was on paranoid android. it was working just fine until today. I flashed cm7, miuigb, miuiv4, jb, cm9 all same result
Format and make a new ext3 and then try restoring.. maybe then it might work!!
Found another backup from before I was using s2e
Restored as much as I could
installed amonra
Hope it doesn't come again

I think it's a hardware problem because if you were on old bb it would recognize the sim card but wouldn't receive any signal

Check if other sim are working on phone. It might be possible that your sim is old and not working anymore. Just get a new sim.
Also dont forget to check the sim terminals on phone.

HELP ! dead radio!

I just acquired a t769 , in pristine condition, alas I have no connectivity whatsoever. No wifi , no GSM, nothing. Tried reflashing via Odin , flashing new modem via CWM... nothing .
I had this issue once. Everything randomly started working again next morning.

still nothing trying Kies now
I think I figured out what is wrong . Whoever had the phone before must have tried to modify settings in engineering mode , because I think the baseband processor is stuck in a test mode..... I just have to figure out how to reset it . Does anybody have any ideas ?
Try this thread, it's the hidden codes for our phone, I'm at work so can't go through an all but here is a link

Thanks but I've tried all of them even via command line . Most of the menus don't even appear , not even band selection or test modes, I tried another Blaze and the codes work as they should.

You seriously need to provide some more info. What did you do before it stopped working? What Rom and kernel are you using? What have you already done to fix it? Have you tried a factory reset? Have you removed the SIM and sd card and reinstalled them?
It's really hard to help with no real information
