I have a PC with windows and my girlfriend has a MacBook with OS X 10.4.11.
I'm not used to Mac, so bear with me.

My problem

We have a wifi connection at home.

We had the same connection at our previous home.

Neither me or my girlfriend had any problems at our previous home, but after we movede, she can't connect to our wifi connection.

I had a bit of the problem to, loosing the connection often. The new place is in a highly populated area with a lot of wifi connection, so I changede the chanel on the router and that helped with my problem.

But my girlfriend still has the problem and can't connect.

Anyone has any idea to help with this problem?
