All wifi devices were working prior to resetting the router's NVRAM. After the reset, Wifi service was restored and the OSX / IOS wifi devices are running well.
DNS-based Filtering (Quad9 Global Filter Mode) was turned on and seems to cause a problem DNS resolution problem on in the Ubuntu box. The Ubuntu 16.04 wifi is able to ping the gateway:
$ ping -c 3 192.168.8.1
however replacing the gateway ip with `yahoo.com` returns:
$ ping -c 3 192.168.8.1
ping: unknown host yahoo.com
yahoo.com resolved to 72.30.35.9 and pinging 72.30.35.9 was successful: this leads me to believe there is a DNS failure.
- The OSX box does not suffer said DNS failures.
- 16.04 wifi works perfectly with cellular wifi hotspot
- Router provides DHCP service
Question
=======
Why would the introduction of the DNS filter only affect the Ubuntu box and no the Apple devices?
