Getting a new dynamic ip address

[rustyshakelford]

I have the smc gateway, and need a new ip address to resolve a routing issue. I understand that the usual mac address method does not work with these, so how can I get a new IP address?

Welcome Rustyshakelford.   We can work with you to resolve any routing issues on the Comcast network.   Dynamic IP's are issued to unique RF mac_addresses.  As mac spoofing is not enabled in the SMC gateway, replacing your current SMC gateway is the only method to obtain a different dynamic IP address.  Please let us know how we can further assist with the routing issue.

Thank you
