Comment(by mbletsas):
OK, did some testing and it seems that we have blamed the correct thing
for the wrong reasons. This is indeed yet another consequence of the
lazyWDS mess.
Briefly, certain lazyWDS-capable access points (like the various versions
of the WRT54), start using WDS frames for all communications with wlan
cards that they observe emitting WDS frames (like the XOs). This means
that the XO sends a normal infrastructure frame to the AP and the AP
responds back with a WDS frame.
We compensate for that on the XO side in order to be able to use such APs,
however at this point it seems that the beacons emitted from such APs fall
victim to the BSSID filtering that we have to do.
Wireless firmware versions 5.110.19.x, don't have the compensation in
place and because of that they can always see the beacons from the WRT54s
Firmware versions 5.110.18.x and 5.110.20.p3+ will see the beacons when
they first boot up and before the AP notices that they emit WDS frames and
switches to WDS.
So if you just have one XO, you can try to shutoff the XO, then powercycle
the WRT54 then try to associate with it (you should be able to see it in
the neighborhood view).
