im currently struggling with this computer trying to get connected to the internet wirelessly... i have a motorola wireless router which is being used by other pc's and would like get connected to that router with this one but its not working... im not sure where to go or what to do for a network... can i make a new network for this computer or do i need to connect to an existing network??? also, the airport icon doesnt show any lines of reception and when im on the window where it should have the list of networks available, it doesnt show any nor does it accept the network being used for the other pc's... does that mean that theres something wrong with the antena ???/ thanks
