You could probably buy another cheap router and connect it to the first one using an ethernet cable. Set the second router to access point mode, and disable wifi on the first router (some routers have a physical button for that). You'll be able to connect only to the second router using wifi, but still use the first router with a physical connection.
There's a bot I've been seeing these past couple of days that is constantly reposting posts with the title cut off in half. Like, it'd just cut it off mid sentence and replace the rest with three dots. I think it's called @L4s@lemmy.world
