Randy- The assumption is that you had a PC hooked up to the cablemodem prior to the current expectation to use the router as the Ethernet host behind the cablemodem.
Whether or not this is true or not doesn't really matter, but... ... in all of my experiences over the last 6 months, pretty much every cablemodem provider has their equipment set up in such a way that the first one or two MAC addresses that are connected to the cablemodem for Internet access are recorded in some MAC Database and paired with the "extended" DHCP lease you get. The only real way to clear these MAC entries from the DB is to call tech-support and tell them you are replacing the network card in your computer, and need to have the MAC table for your modem reset. It's is advisable to NOT tell them you are hooking up a router to it, as they will immediately "go stupid" and tell you they don't support such a scenario - like as if a router's Ethernet interface is any different than any other Ethernet interface! Once they have the MAC table reset, they most probably will remotely reset the cablemodem, or have you power cycle it. This will allow for the learning of the new MAC address to associate with your DHCP lease. This is most probably why you can't get on the net at the current time with your DHCP lease. Let us know if this fixes your problem! Good Luck!

I would like to release the lease recieved from the cable modem (comcast) . I have tried powercycling the modem, router, reload, shuting the interface ect and nothing works. I get the same lease all the time and cant get out to the internet. thanks Randy Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=47182&t=47175 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
