I rebuilt my system a few days ago and have kismet (sort-of) working with my 
new ath-based 11b/g Proxim card.

The problem is, according to it, it's not channel-hopping.  I have it set to 
true in my config, and the velocity is set to 5, and when I start up the 
server it says...

Enabling channel hopping.
Disabling channel splitting.
Source 0 (wtapg): Enabling monitor mode for radiotap_fbsd_b source interface 
ath0 channel 6...
Source 0 (wtapg): Opening radiotap_fbsd_b source interface ath0...
WARNING:  pcap reports link type of EN10MB but we'll fake it on BSD.
This may not work the way we want it to.
WARNING:  Some Free- and Net- BSD drivers do not report rfmon packets
correctly.  Kismet will probably not run correctly.  For better
support, you should upgrade to a version of *BSD with Radiotap.

According to it, it's hopping.  If you fire up the client and hit L, it says 
"server does not have channel hopping enabled".  If you fire them both up at 
once by just running kismet, you can also hit H, and it'll say it's allowing 
the source to hop channels.  Hitting L again gives you the earlier message 
that it's not able to hop.  If you run the client and server seperately, the 
message you get from hitting H does not show up on the client interface, but 
it shows up in the output from the server.

I have an access point right behind my laptop that should be broadcasting away 
like mad, but the card isn't picking it up.  The best I got was the first 
time I fired it up, it picked up a garbage packet.

The behavior is the same between the version in ports and the latest devel 
snapshot from the web site.

Any ideas what I do now?
