Click on the Repeater tab and follow the instructions. Also note:
When you see the list of available wireless networks, make sure the repeater gets a good signal from the router. If the coverage is poor where you placed the repeater, you will need to find a better location for it.
If you are seeing two local networks (one for 5 GHz and one for 2.4 GHz), select 5 GHz. Log on to the network with a password.
Wait for about 30 seconds after pairing for the router and repeater to come online.
The AirTies device has now copied the network name/SSID and password from the router.
If instead you want your repeater to have a separate network name, you can click Advanced and change the SSID and password there as seen in the below screenshot:
Should you later change the SSID or password on the router, you will need to repeat this setup as described above.
