C6250 not detecting ethernet cable
I tried for the first time to use an ethernet cord with my C6250 yesterday. I plugged one end of the ethernet cord into the ethernet port on the router, and the other end into the ethernet port on my...

Thanks for the response!
1. "By "the router", do you mean the C6250? That is a modem router."
Hmm, okay, I assumed it was a WiFi router because in the C6250 user manual it calls it a "WiFi Router". I can post this in the other forum you linked and delete this later.
2. "Is your C6250 connected to the Internet? What do the LEDs on the front look like?"
It is connected to the Internet. I'm typing this post using the WiFi right now :) All of my LEDs are solid green *except* the ethernet LED, though the 2.4 GHz and 5 GHz LEDs are blinking (which is normal since they're transmitting data). The Ethernet LED is off regardless of whether or not it is connected to anything else via an ethernet cable.
3. "What is this "Network Connections window"? Something in Windows on the laptop? A browser?"
Sorry for the lack of clarity. It's a Windows setting in Control Panel. I'm looking at the "Ethernet" option. See attached image, or here on Imgur.
I realized I never mentioned my OS-- I run Windows 10.

The copy I found calls it a WiFi Cable Modem Router on the top of just about every page in the manual. I asked to eliminate any possible confusion.

Two possibilities occur to me: the LAN ports on the C6250 are bust; there is something amiss with the things you are connecting. Can you plug the laptop into a different Ethernet device to confirm that this is not where the problem lies?
I assume that the C6250 is not in "Bridge" mode. You would only need to do that if you were using the C6250 as a modem only and using another device as a router.

Not to _create_ it? This is a LAN problem. What possible difference

Even if it were, do you think that that would affect the Ethernet
LED or the port-status LEDs? I doubt it.
