security concern in my neighborhood

[Pitbull7]

I am seeing a 192.168.100.1 on the cable side of my cable model that's acting as a DHCP server and serving up IPs to the neighborhood .... no clue how to contact security. But if I reboot my internal wifi firewall im dealt 192.168.100.X

made outside IP static to avoid but don't know about my neighbors ??? 

Somebody camping ?? Or something shaw"

That's Shaw's Freedom Mobility Wifi Network from XB6 and Arris Modems.  That can be turned off in the Modem settings.
