nostr:npub1sv4ggaejwe40xxg44qk5z3lctt4p8f2gvcx4uatn8xmyzl4cuursy22h9v depends alot on the wiring and noise in your house. My powering adapters could get 900Mbps if nothing else was running in my house and no surge protectors were plugged in
In a real use case i found 200Mbps was what it was (and good enough for me)
Still, why bother when wifi6 is better
