Okay so i just moved to a new place on the third floor. The land lady on the first floor has DSL . I want to share DSL with there and if i dont get wireless then i will need a lot of wiring to hook my computer with router. My question is that if i decided to get a wireless router and a wireless card would she also need one . I mean can we will still use modem somehow such that she does not have to get a wireless card. Right now i have a internal NIC on my computer . Can any one suggest any other setup. Personally i have never done this and completely new to this.
