I'll hook up two more and try again when I get a chance, I just need to pull them from a working unit that isn't using its wifi currently. >> I didn't see hints in the mwl(4), wlan(4), hostapd(8), hostapd.conf(5), >> or ifconfig(8) man pages about troubleshooting rates.

Try using wlandebug to see what's happening. Ah, I wasn't aware of wlandebug(8). However, it doesn't seem to operate on this mwl(4) card. It sets the value of the sysctl net.wlan.0.debug and that doesn't show up on my system. Another system with a ral(4) card does have that sysctl. Judging by the information in the wlandebug(8) man page it appears as though this may be a side effect of mwl doing much of the work in firmware. I appreciate the information though, thanks for taking the time to reply. I'll continue to work on this again once I relocate some pigtails from another box. Jim
