The 6 GHz wireless band was introduced with the WiFi 6E standard and is exclusive to devices that support WiFi 6E and newer standards, including WiFi 7 and successive future WiFi versions.
If your 6 GHz WiFi device is disconnecting from your 6 GHz network, it might be because the range of the 6 GHz band is significantly shorter than that of the 2.4 GHz or 5 GHz bands. In the same way that the 5 GHz band is faster than the 2.4 GHz band but has a shorter range and doesn't travel as far through walls and other obstructions, the 6 GHz band is faster than the 5 GHz band but doesn't travel as far or through as many walls or barriers.
This means that your device might switch to the 2.4 GHz or 5 GHz bands when you move out of range of the 6 GHz band. Some devices might not automatically reconnect to the 6 GHz band when they are back in range. This is an issue of each individual device and is not caused by your router, access point, or satellite.
To ensure that your device stays connected to the 6 GHz band, place your 6 GHz WiFi router, access point, or satellite in the area where you use your device.
If you can connect on the 6 GHz band but can't access the Internet, or if your devices experience problems discovering your 6 GHz SSID, you might also want to try using a different Preferred Scanning Channel (PSC).
