I have an extremely strange problem with an Airlink101 AP431W access point. I have a small sub-network of three devices linked to a switch. The network was moved to a different room and now has to connected wirelessly instead of wired. The wireless and wired networks are bridged at their common source. This should be a no brainer. And with a WRT54GS configured as an access point and with all ports bridged, everything works fine.
But with the AP431W (AP431W and all three devices connected to a cheapo gigabit switch), only the first MAC address seen works. If I disconnect all three machines from the switch and reboot the access point, whichever device I connect to the switch first works, and the other two devices cannot reach any host over the access point. (The three devices can reach each other when they're all connected to the switch, but always two of the devices can't reach any devices over the WiFi link.)
The AP431W has a static IP address and management works fine in all configurations. I use no authentication, but 64-bit WEP. It's configured as an AP client. Access control is disabled. Advanced wireless settings are all at their defaults.
It looks like the AP431W will only bridge the first MAC it sees. Has anyone heard of anything like this?!
