In this post I will show you how to configure a basic wifi on MikroTik RouterOS router.
For ease of use bridged wireless setup will be made so that your wired hosts are in the same Ethernet broadcast domain as wireless clients.
/ip address remove ether2 /interface bridge add name=local /interface bridge port add interface=ether2 bridge=local /ip address add address=192.168.88.1/24 interface=local
The important part is to make sure that our wireless is protected, so the first step is the security profile.
/interface wireless security-profiles add name=myProfile authentication-types=wpa2-psk mode=dynamic-keys \ wpa2-pre-shared-key=1234567890
Now when the security profile is ready we can enable the wireless interface and set the desired parameters:
/interface wireless enable wlan1; set wlan1 band=2ghz-b/g/n channel-width=20/40mhz-Ce distance=indoors \ mode=ap-bridge ssid=MikroTik-006360 wireless-protocol=802.11 \ security-profile=myProfile frequency-mode=regulatory-domain \ set country=latvia antenna-gain=3
The last step is to add a wireless interface to a local bridge, otherwise connected clients will not get an IP address:
/interface bridge port add interface=wlan1 bridge=local
