I found this: rate_wlan0=( "5.5M" ) which isn't documented in net.wireless, but it doesn't seem to have any affect. I've tried it on the router and the client which uses wpa_supplicant. I still see the rate on the client fluctuate all the way up to 54 Mb/s in the output from iwconfig. The router's rate is always reported as 0 kb/s. - Grant -- gentoo-user@lists.gentoo.org mailing list
