Go into the settings program (the icon with the gears). The second menu option should be WiFi. Tap it and turn on the WiFi by tapping the rectangular button on the top right. Your network should show up in the list, just tap to join.

you can try to set your wifi same as your husband's one, check the wep code and wifi shold be enabled.
try this and give feed back!
good luck

Try turning 3g off, then make sure security of network is wep not wpa personal the iphone has trouble with that

You can try this site....

it may be finding it but not showing the passcode screen to enter your wep key.
tap the wifi settings and set you network information and the wep network key which is located on your router.
If you put any other code in your wifi won;t connect.

I hope you knew this wasnt an Apple IPHONE before you purchased it. This is a IPHONE look alike. It does not support WIFI capability. Sorry....

Your iPhone will automatically switch to the WiFi setting if it is there! No need to turn off the 3g it will use your WiFi 1st, and 3g 2nd!
