“This network is blocking encrypted DNS traffic”
This morning I noticed thatwhen 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.
DNS issue on T-Mobile ISP
I switched to T-Mobile ISP a week back and only reason for that was couple of pretty good offers. From the time I switched I honestly was regretting as I was facing DNS issues with a few websites and sometimes my work VPN too. It will not be able to reach a few websites for a few minutes and then it would just work like nothing happened. Initially I could not understand what can cause this but then it occurred to me that it must be DNS issue. To my horror, I realized that DNS (and in fact even many basic settings) can not be configured on this T-Mobile gateway. I was facing this issue on a macbook, everything else just worked fine so I then thought of seeing what my macbook was using. It showed local network configured as DNS server, I removed that and added cloudflare's DNS1.1.1.1. That has fixed my problem. In short: If you are facing trouble in reaching some websites periodically and this is happening only on a few devicesthen try switching DNS on your device to 1.1.1.1 or some other open DNS servers.
