You could use an Ethernet cable if you got the extended cord and wall bindings to clip it above and away from animals and young children? Might be a better option than random products that usually don't work.
thats like, last pain in the ass option. i'd have to use tape and it would fall often
I used to do it for my connection before I got a better internet, just basic bindings worked, never needed tape or anything. Took maybe 5 minutes to set up?
