No internet access after enabling parental controls
Last week I upgraded the firmware and enabled Circle parental controls. For the next 6 days we had regular random network issues, with our several computers (all LAN) and mobile devices (all WiFi) going offline from time to time. The computers displayed this as an issue with the DNS server, and I would usually be able to "fix" the affected device(s) by manually setting them to use Google's or OpenDNS DNS server. This fix would last about an hour, and then they'd fail to connect to that DNS server. When the mobile devices would run into connectivity issues, we could either manually set their DNS, as above, for a temporary fix, or switch off their WiFi and use, instead, Circle's VPN for mobile data.
There was a lot this going on for six days. So I decdided to disable Circle for two days to see what would happen. All devices connected faultlessly while Circle waas disabled, even using the router as the DNS server. Today, I re-enabled Circle, and all the problems are back. This is too bad,m because I quite like its features.
We had been having problems with our Comcast service right before enabling Circle, so I thought this other thread might be onto something. It still might: if Circle interrupts the router's connection to the cable modem with any regularity, it could be exacerbating that existing issue. I've also read that Circle uses "ARP poisoning;" could that be doing something that knocks out or muddles the DNS settings of the connected devices?
