We have had a product out for several years and not had any issues with DHCP. After doing a recent firmware update we had reports of units not initializing on Belkin routers.
I confirmed the problem using DC 10.72A, RCM5760 module and a Belkin N300 (F9K1002V5). It works on a slightly older Belkin N150 (F91009V2).
The sample program dhcp.c shipped with DC also fails, output below:
========= DHCP.C =========
Enter the following keystrokes:
0-9 toggle specified interface up/down
p ping a host
P ping the same host again
w do a HTTP HEAD request to specified host
W HTTP HEAD from the same host again
t print the interface, router, ARP and DNS server tables
r add a router entry
R delete a router entry
n add a nameserver (DNS) entry
N delete a nameserver entry
f flush an ARP table entry
i set new IP address and netmask
Interface 0 is qualified for DHCP.

This doesn't fail when DC 10.64 is used. Does anyone have any insight into this issue? I'd rather not revert back to 10.64. I am wondering if Belkin have changed something on their side?
