I would just match the manufacturer of your router when getting an extender. Netgear or Linksys… or whatever you use. All the manufacturers make them. Typically $60 or so. They theoretically are interoperable with different companies router, but I like reducing possible issues. I have never had any. I have two of them, one for my main system and one for my headphone system. Nice thing with wired, no passwords to play with..
