@wewe78 . Ping commands were correct.
Ping to router on ethernet is normally 1 ms. Your ping to remote's ethernet is 2 ms longer. Ping to remote's wifi is a bit longer again. Pings to router's wifi are good.
The 2.4G wifi hardware in S20 and homepc is not fast enough to get full speed. And the ethernet ports are only 100M.
When you unplugged the remote unit and got better speed, that might be wifi interference between the router's wifi and the remote's wifi. Is there a setting for wifi channel in the AV600 app?
The VR1600 2.4G speed is 300M but a wifi device has to connect at that speed also. The point of the 200M internet connection is that it can handle higher amount of ethernet and wifi traffic via the router plus some from the extender. The speeds on the 3 devices on the remote's wifi seem enough for streaming; ok for 1 but 2 might struggle. You could try running 2 speed tests at same time through remote's wifi/ethernet.
The speed test can vary during the day; it might be higher during daytime compared to busy evening peak.
On NBN50 plan, I'd expect the devices through the remote to get same speeds as on 200M plan. But there would be less capacity on the internet connection. Depends on how many users and what they do.
How does your hardware setup compare with your friend's? And the speeds?
