Connecting to a wireless network with a macbook

[monkentage]

I can only connect to the wireless network at home with a cable but any other network works as long as it doesn't have a password with it.

The router is a standard netgear job and no one else has a problem connecting to it does anyone have any ideas?

"There was an error connecting to airport network <NAME>"

I set the network up on this computer could that be anything to do with it?
