After restarting my main computer this morning, it wouldn't see the internet. It did, however, see the other computers on the home network, which immediately ruled out a hardware issue. Since my laptop was seeing the internet fine, I "googled" most of the morning looking for fixes.
Turns out the issue was simple to fix. Something I had to last do a few years ago, but has since forgotten about.
After going into the command prompt, I typed in "ipconfig /release" then "ipconfig /renew"... problem solved!
