How often is "lots"? hw tx rate 0x1b is 1Mb/s CCK and 0x1c is 1M w/
short preamble. Both of these rates should be ok to use in 11g so I
don't see why there are complaints unless the ap you are associated to
is doing something like forcing 11g-only operation (i.e. OFDM only, no
CCK). However even with that you should be fine unless perhaps fixed tx
rate parameters are set wrong.
Not sure there's a way to dump the negotiated rate set. You can try
turning on something like:
wlandebug assoc
to see if that provides useful info. Otherwise you might need to
collect a packet trace with something like:
tcpdump -i wlan0 -p -y IEEE802_11_RADIO -w t.pcap
while associating--then inspect the results (and/or send me the pcap file).
