Okay, this is the weirdest thing I've ever seen. My router and WiFi AP don't have internet access, any device connected to the AP or through the router via Ethernet has no access, with the sole exception being my laptop.
Reset router to factory settings: Nothing
Re-upload previous router configuration: My laptop has access through WiFi only, my server has Ethernet access.
The list of access-less devices:
Another Debian 9 laptop
1 RPi 0 w/Raspbian
1 RPi3 w/OSMC
2 Android phones on 7.0 and 8.0
If I can't get get a eureka moment soon, I'll have to go to bed before I bang my head against something.
Tooted too soon, just had my eureka moment.
Realized when running nslookup on my server and laptop --and somehow completely forgot-- is that both of those clients are using OpenNIC DNS servers instead of whatever standard ISP issued one that it defaults too.
Changed the DNS on the laptop and phones: internet automagically works again.
Not sure if my ISP's just a piece of shit (likely) or they're actively fucking with me. Either way, 🖕 to them and I'm glad I can sleep in peace tonight.
