Juste add opt1 interface (ath0) and go to INTERFACES =>OPT1 and you can
configure your atheros based wi-fi card.
However, I had a littl' problem with it :
affter boot ath interface will stay in "no link" state no matter what
option you try.
To bring it to work , go to http://your.ip.of.mono/exec.php and execute :
"ifconfig ath0 mediaopt hostap mode 11g ssid my_net"
After this, everything works fine. I made a bridge with LAN network.
I also did a couple test to see how it performs. My monowall runs on WRAP
board (3xLAN , 1xmini-PCI).
Copy an ISO image between my laptop (same wi-fi mini-pci card like in
monowall , 3054 MP ARIES http://www.netgate.com, DELL 8500, 100Mbits)
and my server (AMD64 3000+, 1GBit LAN) :
1) using wireless : max 1.8MB/S average 900kb/s. At beginig it starts at
~250kb/s and will go up
2) using wired interface : 3MB/S max
Compared to my Linksys WAG54G :
1) using wireless : max 2.1MB/S and it will goes in 2 sec to this speed
2) using wired interface: 8MB/S (well, WAG has 4 port switch built-in)
