2 or the 4 RJ45 ports on the back of my main device have stopped working. I was troubleshooting why my internet was out on a couple of devices and it turns out to be the top two ports, just stopped working. The other two are still working. I plugged a laptop directly into them to verify and neither is working. 

Since I was using all 4 ports to try and take advantage of the 2.5 ports on my network, I now have to rethink how I have everything plugged in and working. I need to swap out this bad device for one of the other two (providing the 4 ports on them are all working still) so I have 4 ports available or I will have to use a 1 GB switch I have lying around, until I can buy another 2.5GB switch. I am not using all 4 ports on the other two satellite devices at this time so only having 2 should work for now. 

Has anyone else seen this happen? These are only a couple of months old. I have never had a port go out on any router before and I have used a bunch of routers in the past.
