Peter,
 
I am running dhcp on a wired interface on a TS-7250 with the full Debian distribution booted via RedBoot from TS without any problems. I am using /etc/network/interfaces to configure it all. I am not doing anything unusual to make this work.
 
Regards,
 
James

OK, now I tried switching to udhcpc for kicks, and I get
"Operation failed." when it tries to run pump.

This is crazy. Getting a DHCP client running on a linux box shouldn't
be this hard.

I had this same problem with a TS-7260 board months ago, and it never
got resolved.

I've tried running against DHCP servers on OpenWRT, default Linksys
boxes, and our regular Slug based system that dozens of machines
connect happily to every day.

Mean time between email responses from Technologic seems to be 2 days.

I was honestly about to roll out a prototype product based on the Wifi
box to at least 100 customers. I'm at the point of going back to the
drawing board on this though.

Is ANYONE running DHCP on a TS box while running full Debian?

Pete
