My powerbook gets awful wifi reception. It's driving me insane. I know they sell antennas online that you can wire into the airport card. I really do not want to open up any of my hardware and do that. Is there any other way to boost reception? I saw this http://www.buy.com/prod/Hawking_Tec...tenna_Combo_802_11G/q/loc/18925/10362460.html I don't know if it works with macs though. Anyone? Thanks.
