The mysterious Netgear Nighthawk CM1150V

Hello, Kitsap. Thanks for your reply.
I am attempting to connect only one laptop computer at a time through the modem. I am not utilizing Ethernet ports 2, 3, and 4. Here's the process:
Xfinity > Netgear CM1150V > Dell Precision 7760. Result: Perfect connection.
Then .....
1. Power down.
2. Unplug the ethernet cable from Dell Precision.
3. Plug the ethernet cable into the Dell Latitude.
4. Power on.
5. Result. "Ethernet doesn't have a valid IP configuration"
By the way, the Precision and Latitude have ESET Internet Security installed. I have experimented with disabling ESET in the Latitude, but that has no effect. The result is the same, whether ESET is enabled or disabled..
Thoughts?
Kitsap is correct. you need a router.
The problem is xfinity. They only assign 1 public ip address per account. (unless you pay extra for more or have a business grade account).
Usually the procedure you followed works. But the problem is, sometimes it takes xfinity a while to reassign that public ip address. Again, its usually minutes but I've seen it take upwards of 30 minutes before during troubleshooting.
Buying a cheap gigabit router and just disabling its wifi (or leave it enabled) would fix your issue as you could connect as many devices as you wanted. You could get a generation or 2 old router off amazon or craigslist/fleabay for pretty cheap and you wouldn't have to fight the issue you're having.
