I posted a while ago asking how to connect my powermac g4 to the internet via my netbook. Since then I have gotten an airport card for the computer- one of the early 802.11 b cards that supports up to 11mb/s. I installed the card, and once I booted into OS X, the computer recognized my network along with a few others around it. But when I try to connect to the network I get the error "connection failed." When I first tried to connect to my wireless network, it had WEP security, but I have changed that to WPA personal since then, and I still get the same error. I know the password is correct, and the signal strength should not be an issue- according to iStumbler and MacStumbler, I get between 75 and 95% signal strength. One possible issue I have noticed is that the signal noise is around 50% at all times, but that is the same amount of noise as any other network in the area. As a note, the powermac is sitting 4 inches away from my PC desktop, which connects to the wireless network just fine. DHCP is currently enable, but I have tried typing in the IP adress other computers on my network sometimes use and the router, DNS, and subnet mask manually, which gave me the same results. I have briefly connected to an unprotected network nearby, which did not give me any errors, and I successfully got onto the internet until I lost the signal. Finally, the system specs are as follows: PowerMac G4 MDD 1.25 GHZ PPC G4 CPU 1.75 gb ram 80 gb HDD OS X 10.5 Leopard Server Unlimited Client The router is a D-Link wireless N router. Thanks in advanced for any help!
