I've been trying to figure out why I can't get WDS + WPA/TKIP working correctly on my home network. I have a WRT54G v2 at home, and the remote WDS station is an Apple Airport Express. I've tried the latest builds of Alchemy and Sartori to no avail. The AP Express is running firmware 6.1.1. From Apple's firmware readme, apparently they increased reliability with WPA over WDS. I've read in the forums and on a few other sites that some folks have it functioning. My Airport Express gets a green status light which means it should be connected. However, when I connect to the Express, I'm unable to ping the Linksys and vice versa. I'm also unable to ping the Airport Express from the Linksys, even though it says it's connected. Looking at the wireless status from the Linksys, I see the MAC address of the Airport and an RSSI usually around 60. I know of the MAC address encryption inherent in WPA that should make it incompatible with WDS, but these problems should have been resolved already, no? Any ideas of what could be wrong?
