ath0 problem fbsd 7.2-release-p3

[Jeremiah Bright]

This is for a desktop, but was told this would probably be the best place to
post this issue....

I installed fresh last night, was able to pull this card up and connect to
my home access point, then I took it out of that mode and made it an access
point itself with hostapd, my laptop was able to connect and aquire a dhcp
address from this machine.  At some point it stopped working, and the box
wont even let me address the card anymore, I've got some dmesg things here,
at one point theres some channel errors, after those happened I haven't been
able to address this card with ifconfig. It's an engenius pci 802.11 card,
below is dmesg and other info.

so it DID work, im not sure what I did to break it in such a short
timeframe?! and I have no idea how to reset it back to how it was when I
first booted

Any help would be appreciated!
