Usually AIRLink dashboard is available at airlink.local/ address, however, this is browser and router dependent and not all routers support the technology needed for this (local DNS). If your router does not support the Local DNS technology, then you can find the assigned address on the settings page of your router and access AIRLink with the IP address (this is usually 192.168.1.X).
To identify the IP address you will need to go to your router dashboard, login and find the connected devices list. Usually, it looks as follows:
