Mikrotik hAP – Change SSID via command line

Posted on November 20, 2019 by admin

Problem – Need 2.4 Ghz network enabled and SSID set to WiFi. Wireless router is behind a NAT, using UNMS to ssh into the radio, and from the radio ssh into hAP. Enter/Return key not working to run commands, so running the commands over ssh from the radio.

Remotly reconfiguring AirMax device

Posted on September 27, 2019 by admin

Scenario: Remote device in a PTP configuration has been reset to factory defaults and is not connected.
Objective: Reconnect remote device and reconfigure using backup file

We’ll refer to Radio A as the radio you initially have access to
Radio B will be the remote radio that was reset.

Reinitiate temporary wireless connection

We know that the default Ubiquiti Wireless settings are
SSID=ubnt
Channel Width=20Mhz
Security=None

To reconnect the device wirelessly we can setup the Radio A as an AP with the above wireless settings.

Setup temporary network connection

Radio B should now connect wirelessly, but is going to be on a static 192.168.1.20 address. There are a handful of ways to overcome this.

Setup a 192.168.1.x network and log into the device. If you are remote you may be able to setup that address range on the router and then ssh into the router or AP then ssh into the remote device
Use a Mikrotik hotspot
Use an SSH proxy

Configure remote device via SSH

Open up your backup file with a text editor and copy the whole config

Once access is gained to Radio B, open up the /tmp/system.cfg file, delete all the contents and paste in the contents of the backup configuration.

Save file and write changes to radio with

/usr/etc/rc.d/rc.softrestart save

Final steps

The device should now apply the backup settings and disconnect again as it should now have the proper SSID and settings.

Restore Radio A’s settings and verify that both sides reconnect.
