The Starry Dash+ has a dedicated 5GHz channel enabled by default. It shares the same WiFi name and password as the 2.4GHz channel, which will allow your device to automatically connect to whichever channel has a better connection.
You can see additional WiFi settings by logging in to the router settings. To access the settings on your Starry Dash+, you will need to log in via IP Address. To do this, connect to your Dash's network, open any browser, and in the URL bar, type 192.168.1.1 and hit enter. Log in using the Administrator Username and Password printed on the side of your router. In the top-right corner, click on the menu. Under Network Setting, click Wireless.
