To set up WiFi on msOS, you will need to have local access to the rig. There are two ways you can set it up: either by using msOS GUI or directly from the msOS console.
You can access the GUI of the rig in two different ways, but it always needs to be from the local network:
Navigate to [Network] tab and click [Configure network] under Network tile.

A pop-up with network configuration will open. Enable WiFi and enter your credentials. Keep in mind that both WiFi username and WiFi password need to be without any special characters and spaces.

Click on [Save changes] to configure the network settings.
