How to Change WAN IP Address
C7000 Nighthawk - AC1900. Firmware Version: V1.01.34 I am trying to change my WAN IP address (my public IP address, not the private addresses). Some information: I called my ISP and the...
No problem. The issue with my setup was that I was using a router/modem combo. To fix my problem, I had to buy a dedicated router, and switch the modem/router combo to only modem mode.
After I had one dedicated modem and one dedicated router, I was able to mac address clone the router (or change the routers MAC address). Once I changed the routers MAC address, my public IP address changed. I can repeat this process whenever I want.
You can buy a router for ~$50. MAC address cloning is the easiest way to change your public IP address.
My ISP is Xfinity.
I've tried to release and renew the lease both on my pc and on my modem.
Sorry for the confusion, I meant I CANT MAC address clone since the modem (C7000) doesn't offer the feature . However, if there is another way to MAC address clone, I would totally be willing to do so.
I've talked to the ISP many times and all they say is that the IP should change "from time to time". I've had the same dynamic IP for many years, and I've tried many times to change it, but it's very sticky.
Thanks for the reply.

Same here. I was thinking of my DSL modem+router, which does allow
the user to change the router MAC address. Cable-TV ISPs depend on
modems having unique (and fixed) MAC addresses for access control. They
don't want your neighbor tapping into your cable and having his modem
impersonate your modem.

If you can't persuade your ISP to jostle things a little, then you
might be doomed.
I think the best option would be to only use my C7000 as a modem, and buy a dedicated router, like an AC1000, so I could use MAC address cloning and overall have more control over my internet.
Thanks for the help.
- Did you ever figure out how to do this? I feel as if I’m in the same boat. Could use any help as I’m sure you know this is a massive headache haha!
