I assume yes. The AP itself has NO IP. Weird. It has a MAC address
though and it has firmware. We have the latest 2.14. Ok, here is
the deal. The gateway and routing work perfectly when I connect
using a Windows PC. But, same PC dual booting to Linux, it does
not work. I can connect and ping anybody on my subnet.

This means the packets reach the AP just fine and are broadcast
back out (RX to TX) perfectly BUT they are not going through
the AP and out the Ethernet interface to the Linux router.

Hmmm. I dont know exactly _how_ the AP bridge functions work.
They might not be very compliant bridging- the producer of the
AP seems to be a chinese special and I have had no reply from
them at all. Dont buy Teletronics. Pay money and get a Cisco,
Intel or the like.

Do you (or anybody reading this post) have any suggestions?
What else can we do? If my packets looked more like a Windows
packet, it would seem that they would work fine. Maybe its
a problem with my Linux driver but I used 3 so far. wvlan_cs,
orinoco and I think wavelan2. I swear the Linux part is working
fine but who knows. Seems like its fine and people report its
ok. Has to be the stupid AP, right?
