A few days ago we were using a SuperHub 2 for our internet connection. Since then, the wifi boke, then the cable's line-in to the modem broke. It was replaced with a SuperHub 3 yesterday.
When pinging the SuperHub 2 router I would occasionally get timeouts, translating as in-game connection loss and rubber banding.
This wasn't a problem, as it only happened occasionally.
Since then we have installed a SuperHub 3. My computer is using the same powerline adapter with wired ethernet.
However now I am unable to even load into multiplayer games. I am specifically getting a "connection timed out" error when trying to join Rust or Space Engineers servers. Occasional Discord and Steam disconnects too during the connection attempts. When using my wifi dongle to connect, I get similar results.
A router network diagnostic gives this. https://gyazo.com/a1c82f6a83cf024466112aee04da7eb5 I would like to remind people the the problem I am facing is reproducible using my WiFi dongle. I think the warning about my wired connection is because the TP-LINK AV600 has ethernet sockets rated at: 2 * 10/100Mbps Ethernet Ports –TL-WPA4220 2 * 10/100Mbps Ethernet Ports – TL-PA4020P
