Sure...output is at the bottom.

Every now and again my connection dies, but it's few and far between. It 
seems to be more when I have the connection up for days on end. It's not 
the actual hardware dying though, because I just do an ifdown ath0, and 
then ifup ath0 and it comes back up fine. This leads me to believe it's 
not refreshing the DHCP lease through my wireless router instead of the 
actual hardware dying. My Linksys router is known to have a few bugs for 
it's particular version, so I assume this to be the issue.

I also get an error when bringing up the interface, but from what I read 
it's an error that can be ignored. Hope this helps you guys. The error is:

Error for wireless request "Set Mode" (8B06) :
SET failed on device ath0 ; Invalid argument.
