I've found a perfect match for my needs: D-Link DWL-G122, with the
"rum" driver. Not a single problem so far, everything works as
documented. Truly a plug and play experience.

I'm just curious about one more thing: I wish to set up a "b/g"
network, so both b and g devices can connect. Apparently this is set up
via the "mode" argument to ifconfig, which accepts "11g" and "11b" but
not the obvious "11bg". Any pointers on this?

You can either omit the "mode" argument altogether and get both supported by default, or just specify "11g", which will also support both. I typically omit the mode unless I want to limit things to only 11b.

Thanks, I'll try that tomorrow. For now, it looks like my fun won't last long:
