Just worked once the firmware had been copied to the right place. Very cool. Now to determine what sort of bandwidth I can push through it…

The first test, wgetting a 700 MB (ish) file from a machine on the wired network, while the wireless network is basically idle except for this transfer:

    playroom:/tmp# wget http://diskbox.stillhq.com/xvid/musicjamboree_one.avi
    --08:18:02--  http://diskbox.stillhq.com/xvid/musicjamboree_one.avi
               => `musicjamboree_one.avi'
    Resolving diskbox.stillhq.com... 172.31.0.61
    Connecting to diskbox.stillhq.com[172.31.0.61]:80... connected.
    HTTP request sent, awaiting response... 200 OK

So, I get about 1.3 mbit from the 54mbit card. Not so good. To compare, here’s the same transfer again, this time from a 11 mbit connection (802.11b) on the same access point:

    sputnik:/tmp# wget http://diskbox.stillhq.com/xvid/musicjamboree_one.avi
    --08:33:02--  http://diskbox.stillhq.com/xvid/musicjamboree_one.avi
               => `musicjamboree_one.avi'

And here it is on a machine with two switches and 100 mbit full duplex between the web server and it…

    deathstar:/tmp# wget http://diskbox.stillhq.com/xvid/musicjamboree_one.avi
    --09:36:27--  http://diskbox.stillhq.com/xvid/musicjamboree_one.avi

That’s interesting. The slow point is apparently the web server at the other end.
