Internet stopped working

[KwiiC]

I watch a video and when I went out of full screen and went to play GTA 5 it didn't load so I went on Spotify and it said "Offline", I tried to refresh my web browser and it said no internet connection and there where no tringale on the internet icon. My phone still had wifi and my brothers computer had internet too. The next day I still didn't have internet but now the tringale was there, I switch cables, restarted the computer and it still didn't work. The was flashing green on the router and no viruses was detected on my computer, could really use some help.

Turn off any Antivirus or Firewall temporarily
Some Antivirus or Firewall can stop you from connecting to the local network. You can turn off them temporarily to see if this resolves the problem.
Make sure the Ethernet is enabled
After trying the tips above, if the problem persists, check if the Ethernet is disabled.

2. Type devmgmt.msc in the run box and click on OK button. The Device Manager window will pop up.

3. In Device Manager, expand Network adapters category.
4. Next to the Ethernet card device name, if you see a computer icon with an arrow on it, the Ethernet has been disabled.

5. Then right-click on the device name. Click Enable from the pop up menu.

Make sure the network card driver is working well.
In Device Manager, if you see a yellow exclamation mark or question mark next to the network device name, you need to update the driver. You can go to device manufacturer's website to find the correct driver and update the driver manually.
