Larry,
Thanks for the response. It appears that "set bitrates" is not
possible with my version of iw (0.9.19) - I get a big long help screen
when I try that command:
"iw dev wlan0 set bitrates legacy-2.4 1 2 5.5 11"
...the options printed out for "set" are:
phy <phyname> set distance <distance>
phy <phyname> set coverage <coverage class>
phy <phyname> set netns <pid>
phy <phyname> set rts <rts threshold|off>
phy <phyname> set frag <fragmentation threshold|off>
dev <devname> set channel <channel> [HT20|HT40+|HT40-]
phy <phyname> set channel <channel> [HT20|HT40+|HT40-]
dev <devname> set freq <freq> [HT20|HT40+|HT40-]
phy <phyname> set freq <freq> [HT20|HT40+|HT40-]
phy <phyname> set name <new name>
dev <devname> set type <type>
dev <devname> set meshid <meshid>
dev <devname> set monitor <flag>*
dev <devname> set mesh_param <param> <value>
...also there's the issue of "basic rates" and "supported rates" I
would need the supported rates appropriate for the mode (such as 'b')
to show in the beacon also.
Thanks again for the response.
