Intriguing problem. Maybe someone can help diagnose it, or tell me where to look. I have a Quickertek b/g PCMCIA card for wireless on my Powerbook G4 (the internal Apple Airport is going flakey.) It works perfectly in normal mode. I can't get it to work in secure (encrypted WPA) mode. It's not the router's problem -- that does work fine in WPA with the airport card (I'm close enough right now the flakiness doesn't matter.) Network status for the port is yellow, "PCI Ethernet Slot PC Card is currently active. PCI Ethernet Slot PC Card has a self-assigned IP address and may not be able to connect to the internet."
Network interface (en2) info says link speed 54Mb, link status active
-- 0 packets sent or received, 0 errors
The card's "link" light is green (I believe this means it's connected fine). The utility for the card says it is connected to the router.
it is configured using DHCP; when I renew the lease I get169.254.189.228 (which has no relation to anything!)
I tried setting the IP address manually to what it's been getting from DHCP; that didn't help. Running 10.4.11.
I'm afraid I don't expect much help from Quickertek -- they don't even have the most current software from Ralink, but I'll give them a try.
