What was the DNS you were using? One of the big ones like Google or Cloudflare or another one?

 

If it's not one of the well-known ones, then it could be the DNS you were using is out of service. (be it temporary or permanently)

 

Thanks for the response! I'm actually using both Cloudflare as my main and Google as my secondary. Thing is, I changed my DNS to 9.9.9.9 (forgot what this was) and the other one was OpenDNS, both of which didn't work. If it helps, I tried testing it in my local systems wherein you put the DNS in the local network adapters and it didn't cut-off the internet when I did so

Regarding network layout, did you mean how my router and modem are physically set up? If so, my gateway router (it's a combo of a modem and a router from my ISP) has its LAN port connected to the INTERNET port of the C80, then the C80 has its LAN port connected directly into the PC.

 

For the DNS, I've been using Cloudflare (1.1.1.1) as my main and Google (8.8.8.8) for the longest time and it's just recently they failed HOWEVER, when I tried different DNS's, namely Cloud9 (9.9.9.9) and OpenDNS (208.67.222.220), they both didn't work. I'll be posting the screenshot below:

 

 

The one in red is where I put my ISP and the current address of that is linked to my ISP's gateway router as of now.

Check if you can successfully "ping" the four different DNS's IP addresses from the router's Advanced -> System -> Diagnostics menu.
