My former access point was an OpenBSD 4.7 laptop and I experienced
exactly the same problems with at least acx(4) and ath(4). Upgrading to
5.0 did not provide a solution.
I recently installed 5.0 on a box with a ral(4) PCI-card but the problem
persisted. However: installing the same PCI ral(4) card on an older box
running OpenBSD 4.6 DID solve it, indicating that the problem might have
been introduced at some level from 4.7 onward?
Cheers,
Erling
