Configuring the GL-AR300M16 as a Routed Client
In some cases, the WAN connection for the router may not be provided via ethernet cable and a WWAN connection will need to be performed so the router can get Internet access via an existing wireless network at the installation site.
Configure the Network
Login to the router at https://192.168.1.1/ and proceed to Network –> Wireless.

Here you will see an entry for radio0,
now press the Scan button to get a list of available wireless networks.

Find the one you would like to use and press the Join Network button next to it.

On the Joining Network dialog, check the box for Replace wireless configuration, ensure the network name is wwan
and enter the passphrase to access the network. In Create / Assign firewall-zone, be sure that the wan
zone is selected before pressing the Submit button.

On the following dialog the defaults should be enough to establish connection, so press the Save button. In some cases you may need to edit the Wireless Security section to ensure the proper encryption is set.

NOTE: If you want to have multiple WAN networks, repeat the above steps but then go to Interfaces –> Add new interface and in the resulting dialog supply a unique network Name
and choose your newly created interface under Device
before pressing the Create Interface button. Afterwards, press the Save & Apply button. You may need to restart the WireGuard interface after this step.
After the dialog closes, press the Save & Apply button and after a few seconds of waiting the router should connect to the network and display connection status in the Associated Stations section of the page.
