I use a Devolo 500 Network Kit
& get very good reception throughout my house.
The throughput, between the adaptors, always greatly exceeds 100M & I don't suffer from Drop-Outs.
Although I'm not on Fibre, I am on a very strong ADSL connection (typ 18M) & these Adaptors have, effectively, become "transparent" (NB:- because of that, I've never tried to run an actual speedtest on the WiFi connections).
However, I'm not into gaming - hence I'm not able to confirm their performance in that role!
