    Default Lack of Wifi after downgrading and unlocking, but do have 3G after fixing. Ideas?

    First and foremost Merry Chrsitmas everyone! First post here and i am in need of some help!

    Right i have jailbroke and unlocked my iphone, when i did this i soon realised that i had no internet (3G) coverage or WiFi when i changed my sim card over. I managed to fix my lack of 3G by altering the network O2 settings and now have 3G back again, but i am still without WiFi, i know it should connect to our internet but it simply isnt finding our WiFi connection.

    Any ideas??

    What model iPhone (3G or 3GS)? what baseband?

    Try with another wifi access point (eg Library, at work etc)

    Some people have had problems with the encryption/security they have set up on their local router. Try turning off encryption (WEP/WPA) and seeing if you can connect. If this is the problem look for a firmware update for your router or try a different type of encryption (WPA2 is the best currently available)

    The iPhone supports all the encryption methods but maybe the router has some non standard extensions or a bug that causes some incompatibilities.

    You need to do provide more information and then do some testing to isolate the problem, are you running the 05.11.07 baseband?

    Did you unlock with ultrasn0w? Did you upgrade from OS 3.0.x to OS 3.1.x?

    Test, try to disable encryption on your router. Try other wifi routers.

    Yeah i jailbroke using blackra1n and then unlocked using the blacksn0w which came as part of the blackra1n download. Its just unusual that without altering the router in any way i have suddenly lost the ability to connect to it when yesterday it was fine. My modem firmware 05.11.07 and all i have done is jailbroken as far as i am aware i haven't installed any custom firmware.

    There have been a lot of reports of wifi problems with baseband 05.11.07 and OS 3.1.x.

    It is not just those who jailbreak and unlock. People who have never jailbroken also have reported this problem.

    Not everyone is affected though.
    The best advice has been to avoid the baseband 05.11.07 if possible.

    Some have reported that restoring their iPhone temporarily fixes it. Others have had limited success with reset network settings.

    Try the security settings on your home wifi, try another wifi access point. You need to confirm if you can get the iPhone wifi to work at all.
