I have a weak wifi signal in a room but I have an ethernet wall socket. I have it connected to a computer and I want to know if I can get wifi signal from that ethernet socket and still have an ethernet output for the computer.
Put in a small Wireless router, connect it to your home system.
- Connect a LAN port on the router to your Ethernet wall socket.
- Give the router a Static IP address on your network (outside of the DHCP address scope) so that the router can withstand restarts and stay connected.
- Turn DHCP OFF on the small router.
- Set up secure Wireless
Now you have both Ethernet and Wireless in this area.
