MikroTik in repeater mode - as easy as One-Two-Three

At first, reset the router settings without creating a default configuration, for example, through the console.

/system reset-configuration no-defaults=yes skip-backup=yes

Secondly, use the automatic configuration command, which will configure the wireless interface to connect to the access point and create a virtual interface, create a bridge interface, and add both (primary and virtual) interfaces to the bridge ports.

In the parameters, specify the wireless interface, the name of the Wi-Fi network and the password.

/interface wireless setup-repeater number=wlan1 ssid=demowifi passphrase=demopassword

Thirdly, add the necessary interfaces to the bridge to the wireless ones and create an IP address on the bridge interface according to your network addressing.

/interface bridge port add bridge=bridge1 interface=all
/ip address add address=192.168.88.2/24 interface=bridge1 network=192.168.88.0
