Steps to Connect Computer Directly to Cable Modem

My router handles dhcp, not the cable modem...From Netgear...By default, the router acts as a DHCP server. The router assigns IP, DNS server, and default gateway addresses to all computers connected to the LAN.

Are you saying when the router isn't connected the Netgear cable modem will provide dhcp services?

Thanks Bruce! When I connect my laptop directly to the cable modem I do not get internet connectivity according to my laptop.

You may need to just unplug/replug the modem to clear its MAC table.  It probably thinks it's still communicating with your router.

Also, ensure your LAN (wired) NIC is enabled on your laptop.  This task should be under your Network & Internet properties.

Going to try it now. Actually, my whole goal is to check the speed I'm getting from Cox Gigablast before it hits my router.

Connecting directly to the modem is the correct way to perform a speed test.

Directly connected my Netgear CM1000 router with my Lenovo Yoga laptop usimg the usb-c Ethernet connector. Only able to get ~500mbps down but got 42mbps upload. any thoughts?
