I jailbreak and unlock my iphone 3g fw 2.1 by Quickpwn2.2-1 and unlock with Yellowsn0w 0.96. I can use it without problem for 3 days after that my Wifi have some problem and now I can't find wifi signal anymore. What should I do?

PS: my router have no problem, I tried it with my notebook, it showed full wifi signal. Thanks

Try resetting your network settings.
If it doesn't work, restore again to 2.2.

I have same problem... none solution

try the other router. Go on open wifi, try if it connect. If it connect then the problem in in your wireless router.


I have the same problem. I have old linksys (modem/wirelessrouter) My 2G connects before, But not now. So i have 2G & 3G that wont connect to my router. So i decide to buy a new wireless router since the wireless-N is better than my wireless-G.
Now i have a longer range wireless wifi and i can now connect both of my iphone.
