Other than now? Could be any number of reasons. Usually one or more of

  1. hardware - computer, router, wifi/cable
  2. software - Windows, browser
  3. infrastructure - ISP down
  4. competence - do you know how to use everything

Yeah, I have to agree that you connected to the Internet to post this question.

If you're unable to connect to the Internet, there can be several reasons for this. Here are some common causes and solutions:

Router or modem issues: Check if your router or modem is turned on and properly connected to the Internet. If not, restart the device and try again.

Network adapter problems: Make sure that your network adapter is enabled and working properly. You can check this in the Device Manager on Windows or System Preferences on Mac.

Incorrect network settings: Check your network settings and make sure that your computer is configured to connect to the correct network. Ensure that the network settings are correct, such as the IP address, subnet mask, and default gateway.

Outdated drivers: Update the drivers for your network adapter to ensure that they are up-to-date. This can improve connectivity and resolve issues.

Firewall or antivirus software: Firewall or antivirus software can sometimes interfere with your Internet connection. Try disabling these temporarily and see if this resolves the issue.

ISP issues: Contact your Internet service provider (ISP) to see if there are any issues with the network that they are aware of. They may be able to help resolve the issue.

Physical issues: Check the cables and connections to ensure that everything is properly connected and functioning. Also, try moving your computer and router closer together to ensure that the signal strength is strong enough.

If you've tried these solutions and are still unable to connect to the Internet, it might be worth contacting your ISP for further assistance.

Look for problems with physical connectivity. Simple issues like a modem, router, or network cable that is loose or disconnected might occasionally cause an internet connection to drop. Your computer's wireless network interface card can be off if you're connected to a wireless network.
