So i resurrected my old DP G4/450/768/10.4 and strangely, it shows 30% more wireless networks than my Mac Pro/Dual Xeon/4gb/10.5 and both HP Laptops running Vista. The G4 has an internal Airport card(i forgot about them there days!). Of course the Airport card knows nothing of WPA encryption and have to disable security to connect. It amazes me that the reception is so much better in this legacy machine.
