dns problems with tl-er6120
I am having intermittent dns problems.
wan1 is a comcast gigabit cable modem.
wan2 is a T-mobile 5g modem.
Wan1 is primary.
Wan2 is secondary.
I can ping an ip address but I can't ping a website.
ping 18.104.22.168 works.
ping google.com fails.
The router will not fail over from wan1 to wan2 when this happens.
It will fail over when I disconnect wan1.
How do I fix this?
