I've recently begun to notice that my Deco X1500 cuts speed to 100M from time to time.

I already set up my connection speed in the app and added my PC as a favorite, but the issue persists.

Main Deco is wired to the secondary one and this one is wired to my PC. Speed should be 1000M.

After I unplug the wire from the main deco and plug it back the speed goes back to normal.

Has anyone found a way to fix this? I'm thinking of returning these units, but I only have a couple more days to do so.
