Okay so using a compat-wireless build of 3.2.5-1, I get the command to
succeed (ie: no more error message) but when I look at the advertised
rates using "iwlist scanning" it certainly looks like the command does
not take effect.
COMMAND USED:
# iw dev wlan0 set bitrates legacy-2.4 1 2 5.5 11
RESULT OF "iwlist scanning":
Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s; 6 Mb/s
9 Mb/s; 12 Mb/s; 18 Mb/s
Bit Rates:24 Mb/s; 36 Mb/s; 48 Mb/s; 54 Mb/s
These Bit Rates are the same as they were before the "iw set
bitrates" command. I haven't actually captured the packets in
wireshark yet; I assume the output of "iwlist" is reliable enough.
Can anyone comment on what is wrong? Why don't the advertised rates change?
