Hi not sure if this is the correct place to post so here goes anyway
I’m trying to hard wire my garage to play fire stick on tv I’ve got the cable run up cat 5e plugged into router in house, what do I need the other end, I have a tplink Wi-Fi extender but stick saying house Wi-Fi out of range???? Any help muchly appreciated

You need something to plug the other end into
Does the extender have an ethernet port?
Or just wifi?
Could just use an old router as an access point
If got one laying around

Yes it does have Ethernet port but still doesn’t seem to pick it up? Would I then use the tp link extender password or the router password?
