Unable to obtain Dynamic IP/use Internet from Cable Modem

Greetings, I have hit a bit of a dead-end regarding a newly purchased AX50 router (I wanted to take advantage of WiFi 6 speeds in a new environment and use link aggregation to boost throughput to a NAS device). I have a long history with computers and know my way around networking, but I am stumped.
Using a laptop, I can connect directly to a cable modem (Arris SB8200) and access the internet as normal. However, upon attaching the modem to the blue WAN port (I've tried both patch and regular Ethernet cables), I am unable to obtain the dynamic IP issued by the modem. I have tried everything I could think of over the last few hours, including releasing/renewing the lease, power cycling every piece of hardware in the connection, etc. I also attempted to get the router to work by setting up the connection as a static IP. I was hoping that if I copied the known working values (IP/subnet/gateway), that this would allow me to get online initially and troubleshoot further from there, but no such luck. I have also tried connecting directly to a desktop computer with a different MAC address, as well as cloning the MAC address from the laptop I was testing, just in case my ISP was not telling me the truth regarding MAC registration.
