I've had this conversation so many times with my partner. She's on an older laptop in a room that's directly through a pretty thick wall from the router, but its still a short distance to bring an Ethernet over, and she's always using her laptop only at her desk there anyway.
She's always yelling at me (who have my desk right next to the router, and everything I use has Ethernet ) that the internet is down again and that she really needs it right now, because work.
But no, getting angry at me that I should do something about it is fine, but that something apparently shouldn't mean the most feasible solution.
I'm not dealing with a WiFi extender for a spot that's literally like 8 meters from the router, for her 100mbs WiFi card.
But it's her loss, at least I have the remaining 900mbps for myself from our plan...
