I must have missed something. For my simplicity, I'll refer to your equipment as Dad's and Son's.
- Dad has a gigabit plan - Son has a 150 Mbps plan - Dad has a coax coming into his house - I'll assume the coax is connected to a splitter - 1 leg of the splitter is connected to Dad's modem (Panoramic WiFi Modem) - 1 leg of the splitter is connected to Son's modem (CM1000) - With both modems online, Cox assigns each modem a unique public IP address - Therefore, Dad is paying Cox for 2 public IP addresses, yes? - Dad's modem has connectivity - Son's modem has connectivity with a laptop directly connected - Meaning...Son's laptop has wired connectivty to the Internet - Meaning...Son's laptop does NOT have wireless connectivity from Dad's Panoramic WiFi Modem - Son's modem does NOT provide connectivity with a router connected
How is the CM1000 a bridge router? It's not a router.
Maybe I described it incorrectly. The CM1000 is a modem and not a router. It simply passes everything through to the RAX80 or laptop. Inside the control panel of the CM1000 I can set the "Starting Frequency" and reset the password. No other options are available. It is extremely simple.
I just checked and the RAX80 is not set to bridge mode. It is most likely set to factory defaults.
