Linksys Mac /PCpc conections

I try to configure a new Linksys wireless router, my Imac picks up the signal, but I can get my note book to work. I follow all the directions but still I can't conect. Does the notebook picks up the Link sys Ip autmativaly, Can enyone help me, thank you

The Linksys may be blocking the laptop. Is this a Win laptop or a Mac? Is the wifi on the laptop turned on?

The laptop is Win and has Win 2k. the wifi card in the laptop is working fine but I still nanot get to the internet, I took my laptop to a friends home that has a Linksys and I could get internet OK, My Linksys is brand new. my iMac pick up the Linksys fine but is conected to LAN. Do you think is an IP problem with my notebook. Thank you for your help

I forgot to tell you that I try it in my friend house , he had a PC with WIN XP and a note book also with wind 2K, is ther a difference in instalation of the Linksys, what could I do in order that my Linksys accepts nor only my Mac but also my notebook. Thanks
