I am running an early 2006 revision 12" Powerbook (the 1.5 ghz with 1.25 GB ram). When I switched my wireless router from a 2wire 802.11b setup to a D-Link 802.11n setup (they're both in the same location in my basement) I noticed that my wireless reception turned to crap. I've always gotten sketchy reception with my Powerbook (damn aluminum case), but I used to be able to get full bars on the second floor and now I can only get service in my kitchen directly above where the router is located. Can anybody help me figure out how to get this to work better?
