I bought my 15" PB G4 at the end of june. I noticed something about it real quickly, the reception for my airport card sucks. As i sit in my room, wiht the wireless router in my basement (linksys 54Mbps 2.4GHZ G) i get between 1-3 bars of reception at times. My brother has an HP with intel centrino and he has full reception in the room next to me. I just bought two 9DBI high gain antennas for my router and i still only get 2-3 bars while my brother has full. These antennas are supposed to increase my wireless range by almost 5X's. Because most wireless routers send out about 2DBI. I dont know what to do, im very frustrated. Should i take it in to get it fixed or something?
