Failing to connect to router or connect multiple devices at once
My ISP is CAS cable. I've been running firmware V3.02.01. For some time there's been some odd behavior with establishing multiple connections to the modem but overall has been working okay as I've ha...

Be sure to swap out LAN cables. CAT6 is recommended.
Power OFF both modem and router for 30 seconds, then power ON the modem then router. Check status on the router. If it still fails, you'll need to conect the mfr of this router for help and support redarding there product.

I've tried using all four of the lan ports on the modem hoping one of the ports may be faulty but none of them register a connection to the router. Any other wired connection to a laptop or desktop is fine, just the router. Is there anything else to try I'm not thinking of or is this more likely a port issue on the router?

What is the mfr and model of the router connected to the modem?
Be sure LAG is disabled on the modem.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Be sure to power OFF the modem for 1 minute then back ON.

Router is a TP-Link AX6000. Signal wise, all is well. If a single device is plugged into the modem it works fine (aside from my router) but trying to connect both my desktop and laptop via ethernet and only one seems to get assigned a valid IP while the other is stuck on "unidentified network"
Also, connection wise it can't get much better. It's connected via a brand new RG6 line that's about 200 ft going directly into the ISPs line from the pole. I've already power cycled it numerous times and various ways and have completely disconnected everything and let it sit for 5 minutes before reconnecting. No changes.

Are you trying to connect other wired devices to the modem? If so, you can't do this. Only 1 device can be connected to the modem and thats your wifi router. The other ports are for other routers however that needs services from yoru ISP which most ISPs only service 1 port, port#1. You would have to ask your ISP if using the other ports is supported or not. You have to connect your other wifi devices to the wifi router for internet services. If there having problems at this point, you'll need to contact the mfr of this router for help and information regarding there product.
