iPhone 3Gs iOS4 WiFi Issues

[Munchzors]

Ever since I jailbroke my iPhone 3Gs with iOS4 (and unlocked with ultrasn0w), my WiFi would stop and not detect any unless I went near my router (like literally)

Sometimes it'll read it, but won't let me connect and i'm forced to reset my router..

I jailbroke with JailBreakMe.com

may I have some help on this?

Does this problem happen with other devices? Could just be the router.

Reset network settings on device.

Already tried that, it's not the router, doesn't even work at McDonald's free Wifi.
