I am running ATT DSL Extreme 3.0 and have a Linksys WRT54G wireless router. I currently only get wireless in approx. half of my house, and the half in which I don't get it, will be needing it. So I am going to need to buy a range extender or wireless access point? I am a college student so I don't have a large budget, but I am looking for advice. Should I stick with Linksys and just buy one of their range extenders, or should I buy an Airport Extreme and hope the N signal is stronger? I am going to be sharing files soon when I get my Mac Mini HTPC setup going on in the living room to this from my other iMac's and MBP. In summary, I am just not sure if it would be worth the extra $ for the Airport extreme or if I should just stick with the linksys.. Thanks!
