If anyone in the world is a true genius, they will have the answer to this question (or problem, rather) I have an iMac G5 with an airport extreme card. I have a PC with an 802.11g wireless card. I have a router (D-Link DI-524) connected to a DSL/Broadband modem. The router (and internet) are supposed to connect wirelessly to both computers. But..... The airport card does not pick up any connection whatsoever whereas the PC picks up a strong signal and the PC is further away from the router than the iMac. The router is 15 metres away from the PC and through 3 walls. The router is 10m away from the iMac through 1.5 walls (1 wall and 1 window). The walls are made of wood. The router is in between the iMac and PC making the distance between the two machines 25 metres. It is on Channel 1. But I've tried it in 6 and 10. When I move the iMac closer to (about 3 metres from) the router, it picks up a signal of about 50% strength (ie half the bars). The PC card cost me AU$39 and the airport card AU$119 !!!!!! Thats about US$30 versus US$90! And the airport card is so weak!!!! Please help me get a signal on my iMac and a strong one at that! Its only 10 metres and 1 wall! Thank you! PS. If you can get me back the hair i've lost over this crisis for the past week i will be very grateful!
