Good day. A few months ago lost my internet connection and after no luck debugging the issue I simply swap my ISP ethernet cable from port 1 to 3 Before swaping: Port 1 ISP. Port 2 Deco Secondary unit

I recently had to forward some ports to get matchmaking to work in a game but when I ran the security check on my Deco app it started warning me that I should disable port forwarding when I don't need
