Change Static IP on AirFiber over SSH



Log into device

SSH into AirFiber

ssh ubnt@192.168.1.20

Modify config file

Open up the “/tmp/system.cfg” configuration file

vi /tmp/system.cfg

Find the line that has the ip address and modify the address.
Note that you’ll need to hit i to enter text if you are using vi

...
netconf.3.hwaddr.status=disabled
netconf.3.ip=192.168.1.10   <-- Change IP here
netconf.3.mtu=1500 
...

Save file by hitting the esc key then type :x and then hit Enter

Save changes and reboot

Now run the following command to write the changes to the device. Once it comes back up it should have the new IP address from the config file.

cfgmtd -f /tmp/system.cfg -w && reboot
