I am using IPCOP, which I believe is based upon ubuntu, and running it on a 500MHz appliance, turning it into a router. When I perform an ipconfig /renew from my Windows PC, it takes about four seconds to get the IP address. I need this to be faster, preferably less than one second. How can this be done? I would think the DHCP server should be able to pick an IP address and send it to the client within a few milliseconds.
