Not to mention that OpenBSD-based access points rarely sustain 54Mbit/s throughput in general. Rate adaptation in the net80211 stack is rather basic. Most of the time slower speeds are selected even if in close range to the AP. There's a high amount of interference where I live and wireless speed usually settles at 1 or 2Mbit/s even right next to the AP. sephe at Dragonfly has made some interesting changes to rate adaptation in his patches to their version of ral(4) and the Dragonfly network stack. I took a look at them once but they're mostly over my head so I gave up on porting them. But such improvements are unlikely to help a 133Mhz PC anyway :)
