Boy, is my face red :-[  My apologies for not reading the details in 
your very excellent man page for ap-config.
BTW - http://desync.com/linksys/ is no longer a useful link, but the 
other two links are very informative.

Oh, just that I picked up  2 D-Link AirPlus APs based on the ACX100 chip 
set from TI (for 802.11b x 2
transfer rates in principle).  The last report I saw about these and 
similar APs or modems is that Linux drivers
won't be available for them until December.  Maybe it would be better to 
wait for 802.11g chip such as Intersil etc.
are demoing at Comdex to get both higher bandwidths at 2.4 GHz and have 
them based on soon-to-be standards?
