SENSE is connected to an upstream router via WiFi. In the upstream router settings, the Airtime Fairness option has been enabled. The SENSE router screen shows the disconnected symbol which means that the internet connection to SENSE is down.
We have tested this with the Sagemcom FAST3686 cable modem, and it seems that SENSE does not support the Airtime Fairness option enabled if SENSE is connected to an upstream router via WiFi.
Note: If, however, SENSE is connected to the router via Ethernet cable, the internet connection works without issues.
To restore the internet connection:
Disable the Airtime Fairness setting in the upstream router settings OR
