Wi-Fi repeater enables you to repeat an existing wireless network and extend its range
Starting a repeater
The most likely network you want to repeat is selected by default. You can click 1 and select any of the networks known to Windows.
If you use multiple network adapters connected to the same network, you can also select the network adapter you want to repeat the network from.
The firewall options allow you to change whether to allow or deny traffic to devices. In 1, you can change whether you want to block advertisements for new devices. In 2 + 3, you can change whether you want new devices to have access to the internet and your local network. The access rules are saved per device and can be changed if desired.
