So I follow Linus Tech Tips and set my computer's DNS server to 1.1.1.1 but the dumbass in me didn't set any backup servers.

Come Friday night, internet is not working on my computer. After a modem/router restart and it still not working, I thought it was just the internet in the house was down for a little bit (it was connecting to the router perfectly fine). The next morning I wake up and my phone's connected to WiFi and it's working, so I'm like, "great, internet's back"

Not for my laptop lol. Nothing's loading there. Since it's just this device that's having trouble, I decide to forget the network and log back in. Still not working.

I finally remembered my DNS server setting and add Google's external DNS servers to the list and now it's working.
