RAX50 AX5400 no internet connection
My RAX50 just randomly lost internet connection. Internet light is solid red. Since this has happened I've fsctory reset countless times. I managed to find out the nighthawk app was preventing it fro...
The cm1200 has 4x ethernet ports. But comcast only supports 1 device connected to it.
So try this. Power off the router and the modem. Disconnect the coax from the modem.
Wait 2 minutes.
Connect the coax back to the modem and power it on.
Wait 2 minutes.
Connect port 1 on the modem to the wan port on the router.
Power the router on.
Wait 2 minutes for it to fully boot.
Attempt setup/using the router.
Make sure to only have 1 device plugged into the cm1200.

DUDE...... It worked, thank you so much! I don't understand why comcast chose to do that. That's a waste of 3 ports. Probably because it's not their equipment.
- Glad it worked for you! It happens because Comcast wants people to pay extra for more than one public IP address.
Glad you got it working. Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.

Probably because it's not their equipment.- At one point I had my ps5, and an amason fire cube plugged into the cm1200 and it ran fine. I recently had an outage, and when it came back up nothing was working for awhile. Do you have any recomendations on getting around this aside from getting a router with more ports?
The CM1200 doesn't have a router as mentioned already, so connecting the RAX50 to the CM1200 port #1 will work. Then connect ALL other wired and wireless devices to the RAX router.
