When I set up people to work from home and see some of the WiFi set ups they have, I just tell them to go wired if they can. They wonder why their internet is slow when they have one AP and it's on the other side of the house. Also it's the one their ISP provided and it's 10 years old.
It really depends on what you are doing and what you are expecting to get out of the experience. For instance, streaming a game from a gaming pc to a Steam Deck or other portable unit works best when the pc is wired to the network.
But that's why you would put it near the router so you don't have to use 100 ft of cable to do it, so meh.
Yeah, unfortunately my house is pretty old, so there's exactly one spot I can place a modem/router. I could centralize the router, but it always ends in a cable 🙃
Well, I use mine to stream games over wifi and it works better when my pc is wired. Different situations require different set ups. That's the beauty of having options.
Yea, I just moved into a little apartment that only has wifi from the landlord's house. I was skeptical about it, but it's been almost a year now and not a single problem with it. I used it for my PC, cell phone, TV and tablets. I have never had to ask my landlord to "restart" the modem.
