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.

Well that explains the multiple device problem I guess. I'm still unsure as to why I can't seem to get it to recognize a connection with the router. With only the router being connected, no LAN ports show any LED activity. The router gives an error that a network cable is unplugged. 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?

"odd" is in the eye of the beholder.
If your ISP has alotted you a single external/public IP address,
which would be typical, then you should be able to connect exactly one
device directly to your modem. If that one device is a NAT router, then
you should be able to connect multiple devices to that NAT router.

A modem with multiple LAN Ethernet ports doesn't change that.

I'm not amazed.

Huh? Which ports on which device? What, exactly, are you connecting
to what, exactly? (Hint: If a device has different types of ports, then
"connected to device" is not enough detail.)
"it" the modem, or "it" the router, or what? "recognize"? Does "it"
speak the words "I do not recognize", or are you interpreting some
event(s) in the real world?
As usual, dhowing actual actions (commands) with their actual results
(error messages, LED indicators, ...) can be more helpful than vague
descriptions or interpretations.
Also, a vague description of what does _not_ happen is less useful
than a clear description of what _does_ happen.

Did you consider trying this radical concept (which works for some
people):
https://en.wikipedia.org/wiki/RTFM
Visit http://netgear.com/support , put in your model number, and look
for Documentation. Get the User Manual (at least). Read. Look for the
LED descriptions and "Troubleshoot". Further reading might not hurt,
either.
