when using a wireless router, do i have to type an IP address to get the signal from my roomates computer?

Question

I have a wireless card, but when i ran a virus program, I somehow lost the signal from my roomates computer, I even unplugged the wireless card and it still won't recognize a signal from the next room.???

Answer 1

well since the "signal" is coming from the wireless router, I don't think you need your roommates IP address to access the wireless router. You need a wireless card and a wireless client. If you mean, once you're connected to the wireless network, and you want to access your roommates computer, yes then you need his IP address at a minimum.

Answer 2

Just to use his internet connection, no you don't need to do anything once your wireless card picks up the signal it's basically just sharing the connection.

Answer 3

You shouldn't, but if you roommate is using a protected network you will need to know the user name and password to connection, you always need a good signal to do anything.
