Re: flaky DHCP

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance


However, when I replace the Linksys router with an SMC router I'm not
getting a good DHCP address. How do I figure out why not?

Does the router separate the DHCP clients from their
server?

If so, then most likely you need to make the setting on
the router that is equivalent to "DHCP Relay" (aka
"IP Helper address" by Cisco, IIRC) or "Bootp
forwarding."

The clients BROADCAST must either be relayed
or forwarded to the DHCP server if they are not on the
same "broadcast domain" (i.e., a router separates them.)
