en faite il y a une petite astuce pour activer le wifi apres un jailbreak (quickpwn).
vs allez dans reglages, puis dans generale, ensuite vous aller dans réinitialiser et
la vous faite un reinitialiser les reglages reseau, vous redemarrer el la comme surprise la connexion wifi apparait.
You must go after jailbreak in settings module, than in general an than you must reset the network settings, after that you restart the iphone an the wifi connection will go on.
Im having the same exact problem, went from 114 to 2.1 firmware, did the Quickpwn for 2.1 and now the phone wont connect to my home network. All other devices connect to it fine so I know the phone is the problem...
this is my problem too.. i cannot connect on wifi, my cydia is not working well., cannot download winterboard,cannot ssh my phone, any suggestions of what should i do, pls,,
one more thing, how come my ip address(wifi) is different than my phone wifi ip, is this normal? pls help
I saw this problem in a couple phones. No problem on a simple upgrade and jailbreak, however when you unlock it the wifi signal drops to almost nothing. I had to sit right next to my router to make connection. Must be something in the qwkpwn unlock portion that kills the wifi.
Since Upgrade to 2.2 and jailbreak (quickpwn 2.2) + unlock (YellowSn0w)... It looks like it searches for wifi available, but never finds any, tried everything everyone says and nothing.
So then I thought that updating to 3.0 would fix it, and it didn't. Used redsn0w to jailbreak and ultrasn0w without wifi method... Still no wifi.
Hope someone knows what this may be. I`m sure that iPhones memory isn't wiped when you restore.. Some config files must remain and that might be a good start for programmers.
