I’d expect your FP to get the DNS server IP from the DHCP server in your wifi network. So it’ll revert the setting every time you connect to this wifi. This is why I think you may probably have to change the setting on the DHCP server.
The AP it is connecting to has the PiHole set as the DNS server to assign. Also, as I sad before I’ve specified a specific DNS server in the WiFi connection settings, which I’d expect to be overriding anything assigned by DHCP (otherwise, what is the point in that screen!)
This is really annoying now. Every now and then, the Fairphone is completely ignoring the statically assigned IP details and deciding to use different ones. Why would it do this?
When I spot it (I spot it when I suddenly start getting ads on Duolingo when on WiFi at home) I just need to disconnect the WiFi and reconnect and it uses the DNS server I’ve specified in the static assignment section
Just guessing, but taken together with the fact that re-connecting Wi-Fi (presumably by turning it off and then on again) leads to using the correct DNS server I’d guess that rules for switching DNS server may have changed in A11. For example, maybe the default behaviour is now to remain with the current server even if switching networks.
Does this mostly happen after you’ve been out of range of your home network?
You might be interested by this article. While the talk is of an announcement, I suspect Google announcements may not always precede the changes they announce. Indeed, the official blog says “by the time you’re reading this …”
Yeah I think this is the case. I was away this weekend. Before leaving, no ads. Got home, reconnected to WiFI and my DNS server has changed to my router (rather than google this time) which is NOT what is specified in the static addressing bit. Disconnect and reconnect and the DNS is back where it should be.
