This morning I noticed that when my iPad and iPhone connect to the WiFi signal from my 5G High Speed Gateway (the silver trash can) they warn me that “This network is blocking encrypted DNS traffic.” It goes on to state that internet traffic on the network may be monitored and recorded by other devices on the same network.
I have an Eero router connected to the gateway by ethernet and configured in bridge mode to serve as an access point. When I connect to that WiFi signal I do not get the same warning message.
I have already:
(1) rebooted the gateway several times
(2) done a factory reset
Another odd symptom — which may or may not be related — is that it continues to show a warning on the LCD for “modem storage overload.” I noticed this a few days ago, but it has not been resolved by the reboots or the factory reset. There are no text messages in the device.
