ETHERNET PORT NOT WORKING

[micselafey]

I have an AC1900 Cable Router and 1 of the 4 ethernet ports has stopped working. It actually switches ports because I've had to unplug/replug my DTV several times into a different port. Way out of warranty obviously. Is there a way to test ports on a cable router? From the attached it looks like Lan 3. If I can't get this problem fixed I will never buy NG again since this is the 2nd router I've had problems with.

Hope someone can help.

You can test ports on them. Usually they way you are with just having a device connected to it. 

have you tried swapping the ethernet cable between 2x devices to see if its a port issue, a device issue, or a cable issue?

Thanks for the reply. After watching it after I posted it may be the DVR. That is the only thing that doesn't work then I switch the cable to another port and it reconnects. Going to drop DTV soon anyway so we'll see.

Thanks, Mike
