I have roadrunner cable modem service and a 2514 as my internet connection. When I need to get another IP address I simply shut the interface down, wait a few seconds and do the no shut. To verify that you have a new IP address do the "show dhcp server" command, it show your IP address, the IP address of the DHCP server and the lease time. ----- Original Message ----- From: "Phil Lorenz" To: Sent: Saturday, June 22, 2002 7:56 PM Subject: RE: Cable Modem DHCP problem [7:47175]
