Gigabit ethernet speeds for wired connections are 1GBit/s which translates to around 78Mb/s in ideal conditions.
Wifi6 (AX) speeds are also max 1Gbit/s and you have to be very close to the router to achieve those speeds. In most instances it will be 0.5-0.75Mbit/s.
To achieve 10Gbit speeds you would need 10GBit networking equipment on the router AND the endpoints and only a tiny fraction of people have that. Due to network congestion etc I doubt you would get those theoretical speeds even if you did have 10GBit hardware. Hpwever, who knows, I haven't seen any detailed figures.
if you want the max speeds you can get on 10GB fibre you need:
A good router with a 10GBe port, for example this. https://www.digitec.ch/en/s1/product...upplier=406802 A PC or laptop with a 10GBe port. You can add one to a desktop PC using this https://www.digitec.ch/en/s1/product...E&gclsrc=aw.ds Then if you have network storage like a NAS, ideally it would also have a 10GBe port.
You would then be in 10GB heaven. 10GB will of course come down in price, but it will be slow.
This one mate but you can get rebadged similar ones from Amazon.de as well. For the cost I think its a great bang for buck vs 200 CHF for a 10Gbit one.
