I have a couple of Ubiquity XR9's. They use an AR5413 (168c:001b, ss
3009:0777) and downconvert to the 900MHz ISM band. The default channel
width is 20MHz and confirmed by my spec analyzer. I'd like to use them
at 10MHz and 5MHz.
My searching turned up very little. Ubiquity released an unsupported
hack to madwifi that compiles against an old kernel, but the channel
width changes take place in their binary HAL. There also appears to be
support in the madwifi driver (proprietary HAL version 3314) by setting
/proc/sys/dev/wifi0/channelbw, but it doesn't seem to work. The call to
the HAL routine to change the width returns an error. Further, that
support// disappeared in the open HAL version. Nowhere was there any
information on what values go in which regs.
I see that there are some TO DO comments in the ath5k code for
half/quarter channels. Is this being worked on?
If not and somebody on the list has the needed info and would be willing
to suffer some dumb questions, I'll try to add it.
Steve
