The thing is that we intend to implement time divsion multiple access in
WiFi with support for multi-channel operation. We have already implemented
time synchronization mechanism in madwifi, which took us considerable
effort. Now shifting to ath5k will again take up time as we are not
conversant with ath5k code.

Yesterday again I tried with latest release of Openwrt Kamikaze  ie.
v8.09.2, but still I get the same problem. But the madwifi code works
properly on IBM latop running Ubuntu with Linux kernel 2.6.24-23. So I guess
it is the issue with Openwrt or the hardware ie. AR71xx boards. Has the
latest code been tested on Openwrt and Ar71xx boards??

Thanks
