Assume that I have a router with DHCP server on it (well, it is actually a dd-wrt router). After rebooting the router, all the DHCP clients's hostnames are lost: I couldn't see the names of the clients except IP addresses in the "active clients" page of the "LAN" status tab in dd-wrt.
The DHCP clients wouldn't resend their hostnames automatically unless they are trying to renew their IPs. Is there any way that I can force the clients to resend?
Thanks a lot!
