NH RS300 - QoS
Does the RS300 have a QoS feature? According to the manual for the RS300 I have access to there should be a QoS feature in the router. This is a screenshot of the manual, page 104. I the...

When I tried out powerline (some years ago), I found some outlet pairs that had terrible performance. But not that bad. Were these AV2? Or something older?
If powerline is out, then you could also try a USB WiFi 7 adapter (assuming you are connecting to a PC). You'd connect it directly to the R300 wifi.

Yeah, that is not ideal, especially when the circuits go to different breaker boxes.

Obviously do the same test connecting the laptop to the extender ethernet.
Another useful test would be to measure the wifi speed from the gaming location, but connecting to the RS300 instead of the extender. That would be particularly useful if the laptop doesn't support WiFi-7. The extender backhaul link should be about the same speed as the laptop wifi connection, so the test would let you see what the limit is.

Yes, brand new - just returned them to the store a week ago.

The adapter in the PC is a A8000, but the RS300 is too fare away to get a stable signal (hence the extender). It's in a different floor with concrete floor divider.

If the adapter connection is poor, then the extender backhaul will also be poor. Retransmissions on the backhaul likely is the cause of the bufferbloat (since the extender needs to buffer the packets until they are delivered to the router).
As plemans says, MoCa is another path if you have coax in both rooms. Or (if you own) contact an electricion and see if it is practical to run ethernet. If the wiring runs through conduits (often the case with concrete construction) that might be possible (and affordable).
