NetGear for me. Metal casing, just a bit nicer quality than the really cheap stuff. I have a managed one for 2xNAS, PI and some other kit although I hardly ever look at the UI. I think the 5 port one I have in the big shed here was about £40. Gigabit, auto sensing, standard stuff just done well.
On the Deco not connecting well (and I see you’ve fixed it) it might be worth running the network optimisation function in the App (under more)- sometimes it’ll move channels around to get a better connection if you did want to connect any wirelessly.
