On F15 (probably v15.0), it says something like it's missing firmware (even on the internal wifiG module, IIRC). I suppose if I really want Fedora, I could download the latest v15.1 release (2011-Jun-03). Maybe that will have what my wifi devices need.

How do I tell Knoppix to make the USB wifiN the default so that internet traffic prefers that one? I tried searching the web for this but perhaps I'm just not searching with the right terms. I guess it would just be easier to connect via cat5.

Is there no way you can bring this box to an installfest or friend's
house to get your updates? Are you really tied up 7/24, vs. the time
(and $) you've already spent on this problem?
How about a device like this Cisco-Linksys WET11 Wireless Ethernet
Bridge to go from your web device to ethernet for $25 or less?
This is only 802.11b, but there are similar devices that do g and n.
