I need some help with an upcoming purchase. Im in the market for a used laptop. Something in the $400 range. My main priorities are for word processing and wireless internet. Im completely new to wireless internet and I have no idea how to set it up or what I should look for in a laptop (what wont work wireless, if a laptop has a wireless card etc.) My PC does not have a wireless port, but it does have some sort of network port and 56k modem I think. Im running Rogers cable internet with a cable modem. What are some things I need to look for? Things I have to buy?
