required modules include pcipool, zd, usbcore, usb-ohci, usb-ohci-ep93xx, and
af_packet. (Some of those may be spelled wrong, I'm going from memory).

Yes. I prefer to edit /etc/network/interfaces and spec it out there, then
"ifup wlan0". You can add lines here in the wlan0 stanza like
wireless-mode managed
wireless-essid myhomelan
wireless-key 1234567890

I've been through this recently, with a TS-7200, not a 7400, but it should be
similar. WEP is pretty easy, usually just iwconfig wlan0 key xxxxxxxxxxxx.
WPA is somewhat less trivial. I got it working after several full days of
trial and error. I explained what I had gone through to Michael at Technologic
Systems (they didn't have it working at the time) and he was able to get it
working "off and on", although he probably has it perfected by now. If you are
interested, I'm looking for a guinea pig to try to recreate my efforts with the
hope that we can create an actual HOWTO with the proper steps. It involved
patching the kernel with appropriate "Wireless Extension" patches, recompiling
the kernel and just about everything else. On the other hand, I see TS is kind
of pushing the 7400 as a "wireless appliance" so they may have everything ready
to download, and plug and play to get WPA now. For your sake, I hope so. :-)

What I do (with TS-7200 compact flash cards) is connect to my PC with USB flash
card reader, and use "tar" to create a single file on my PC which is an image of
the card. I think some people may use "dd" instead of tar. I can't comment on
the pros and cons, just that I use tar and haven't had a problem.

You're welcome. Hope that helps.
