Alright, I've tried a few other things and I think I've got a better
idea about what's going on.
This card had been working under a 4.3-stable system, so I tried a clean
install of 4.3-stable to verify that nothing special needed to be done
to make the pgt0 interface work. I found that it does work.
Next, I tried a clean install of 4.4-stable, and found that the problem
immediately reappeared. Looking at the changelog for 4.4, I found this:
"Make sure the 802.11 layer drops unencrypted frames when WEP is on, or
when WPA is on and RX protection for TA is enabled."
This sounds like it could produce my problem, but the access point's
replies look completely normal and all other devices are able to
communicate. Is there any way to find out if this is what's happening? I
suppose the next step is to pick through the revisions between 4.3 and
4.4 in the code from src/sys/net80211/. Is this the correct place? (I'm
kind of new to OpenBSD.)
Thanks
