If you have a hard wire where you are placing the extension wireless router, there's no need for a repeater -- those
degrade overall wireless performance and are a fine bandaid
if you don't have a wire:
One downside of wireless repeaters, though, is that they reduce throughput on the WLAN. A repeater must receive and retransmit each frame on the same RF channel, which effectively doubles the number of frames that are sent. This problem compounds when using multiple repeaters because each repeater will duplicate the number of frames sent. Thus, be sure to plan the use of repeaters sparingly.
I wired every damn room, some more than once. I took advantage of that to add a $20 TPLink to extend coverage to areas outside our home.
Here are the steps, starting with taking the TPLink out of the box:
- Plugged in the TPLink to the wall power (not the network yet)
- Connected a computer to it via wireless (but you can do it via wire too on a LAN port)
- Logged on to TPLink admin console (default -- 192.168.1.1; admin/admin); disabled DHCP (DHCP|DHCP SETTINGS), set LAN IP to 192.168.1.2 (NETWORK|LAN)
and took note of the router MAC address, changed the SSID to match the main network (WIRELESS|WIRELESS SETTINGS).
- Rebooted it
- Plugged in the RJ45 wire into the LAN port
- Logged on to Netgear Nighthawk and assigned a static IP reservation to the TPLink (ADVANCED|SETUP|LAN SETUP) using the noted router MAC address
I then fiddled with various placements of the TPLink to maximize my coverage (using the Xirrus tool mentioned earlier). I found there was little difference between the upstairs window and downstairs window atop a bookshelf.
Done.
I'm guessing that you might have messed up the order above and gotten the TPLink into a state where you might not be able to access it successfully. Just reset it and start over again.

Good luck!
