It would seem if the DNS server information were missing, then all devices connected would be having connectivity problems. That is not 100 % true, since you can define the DNS server in many individual devices.
Most routers, when connected to the internet, will pick up the DNS information via DHCP from the ISP’s servers. But, you can override that if you want.
If you log into the AirPort, does it show what DNS servers it is using? I’m not familiar with the AirPort, but assume you can at least see that.
When the DNS server information is missing, or bad, you should still be able to connect to sites using an IP address — just that a URL isn’t able to resolve.
Instead of the DNS servers provided by Spectrum, you might (temporarily at least) try using some of the free public ones available — like 126.96.36.199 or 188.8.131.52.
