Hello, my Archer C80 dropps connection randomly every one-two-three months, hard to say exactly when. The connection light becomes orange, and a restart always fixes the problem. Since I run a server behind it, it's way too often to be acceptable for me. It runs the newest firmware, for it's 2.20 hardware version, but the update didn't fix the problem. Here is the log, but I doubt it will be helpful, since it looks too short for me. Should I return it, or is there something I can check?
