i purchased my friends wireless ADSL router because she is moving to australia to use with my laptop, i have a Toshiba Satellite A100, she has given me her network key, but its coming up with acquiring network address, and wont connect, just sits on that for about 10 mins before i get sick of it

is there any way i can get rid of her info so i can set up my own network key instead of hers? or was it just a waste of money?

thanks in advance for any help you can give me
