I have 2 X68's set up at my house and have had no issues.

Internet randomly dopped out and I got red lights.

I swapped the two Deco's and used the satellite as the main and this unit started working again.

The old main (now satellite) unit is having issues. It will connect to the network if i set it up using wifi only, as soon as I plug in the ethernet cable connected to the main unit, I get a solid red light and have to remove from network and reset it and connect back using wifi only.

Has this happened to anyone before and is there any potential solution?

Thank you
