Hi,

After 7.2-RLEASE -> 8.0-BETA2 update my notebook wireless works
without problems but there are lots of annoying "ath0: bad series0
hwrate 0x1b"-like messages on console now.

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).

There are 5-30 messages a second when bandwidth usage is high.

The noname AP looks really strange and it may do something wrong.
Actually the question is rather why I did not see the messages for the

tcpdump and wlandebug results have been sent privately.
