I realize this is not a dd-wrt support forum, but is there a blurb
on the website which helps navigate which branch of that release is
most appropriate for what platform? I suspect the "generic" is
the right answer, but I can't really defend that suspicion :)

Just trudging through the forums is kinda slow :)

FWIW, using KNOPPIX, I get a DHCP timeout. I'm in the process of backing
this machine up to reinstall Doze - it won't even allow setting a fixed
IP without crashing.

This is an *OLD* version of XP, 2002-2001 vintage. Meh. If all else,
I'll rig up a .bat file with a rarp command.

I get nothing on the main machine hooked wired Ethernet directly to the
router that is the DHCP server. :( That path does not include the dd-wrt
box at all.

The machine that cannot DCHP wirelessly can DHCP wired.

The MAC already has a DHCP supplied IP address, so I don't blame it. Un
fortunately, the machine in quesiton is in use. I'll hook Ethereal up
later.

Thanks much, Jeff.
