Comcast router (CGA4131 Business Gateway) assigning out-of-range IP4 addresses?
Why would a Comcast router (CGA4131 Business Gateway) that normally assigns a 10.1.10.x IPv4 address to PCs and devices suddenly start assigning 172.72.35.x IPv4 addresses? Yep - 172. This was unexpected and caused havoc with devices communicating with one another. Some were just randomly switched to the 172 addresses while others remained with their original 10s. The SSIDs changed to their SSID 2 counterparts. Wifi and wired devices both affected, though it was the wifi devices that seemed to take the brunt of it. Restarting/resetting router, resetting wifi profiles, DNS flush, ipconfig release/renews, network resets did nothing to solve this problem. While assigning fixed IP addresses with the 10.1.10.x range works, it still doesn't help explain the change.

Hi Finnegan0805, we are happy to look into this for you from our end of things. Can you tell me if you're connected via VPN when this change occurs?

I am having this same issue. I tried calling the 1-800 but the helpdesk representative refused to help troubleshoot anything with me.
