Years ago I bought a Epson WP4515 printer/scanner. It had Ethernet and no WiFi but it had to sit just by the PC so it wasn't an hassle back then. One day however I had to move things around and it would suddenly need a long cable to connect to the nearest Ethernet switch. Fortunately I had at hand a bunch of TpLink TL-MR3020 mini routers I had bought literally for coins at a flea market because I knew they support OpenWRT, so I grabbed one, installed OpenWRT and set it up to bridge the Ethernet input to my home WiFi, and bingo, the device was online without cables. If anyone is interested, those small routers are sold as 3/4G routers for being able to host a 3/4G dongle modem in their USB port but actually they contain no mobile modem, they just have 2.4GHz WiFi, one Ethernet port, one USB port. They are also ridiculously limited in HW capabilities, RAM and storage, etc, however they can run old OpenWRT versions, which makes them good for that use.
