Thread: iphone 3g ios4 wifi not working doesnt show any network at all.

  1. #1
    Default iphone 3g ios4 wifi not working doesnt show any network at all.
    i just got this phone and im new to most of this. the wifi just isnt working. i jailbroke it with redsn0w and unlocked with ultrasn0w. in order to unlock i had to add repo by using diskaid. it worked but now i really need wifi to use cydia to add tmobile carrier packages and other stuff. today i was sitting closer to the router and my network came up for a second but then went away. kept trying it and didnt work. tried other networks and still nothing do you guys think its a hardware issue or software. any help would be greatly appreciated.

    if you have an ATT sim

    Restore the phone to stock 4.0, using the att sim the activate it (doesn't have to be active)

    then test the wifi

    If still nothing, its most likely a hardware issue.

    (it helps to have a friend over or something with an iPhone to see if they can see your router, cuz its possible it could be that)

    how do i add it i dont have wifi and i dont know how to add repos without wifi unless i have some kind of instructions. in order to add the ulrasn0w repo i found it on youtube some guy added it through diskaid. kinda like ssh but using a usb cable if you didnt know. so if you know how let me know so i can add that repo any help would be appreciated since im kinda new to all this.

    i also noticed that i have firmware 4.0.1 and it is still unlocked works fine except for wifi like i said. is this right that its unlocked even tho its on 4.0.1
