Here are some quick tips that you can do to troubleshoot your computer network.
1. Check for ISP outages: Contact your Internet Service Provider (ISP) or check their website/social media for any reported outages in your area. Sometimes, the issue might be beyond your control.
2. Check other devices: Verify if the internet is working on other devices connected to the same Wi-Fi network. Make sure that they are indeed on the same wifi network. If they are, the issue might be specific to your device.
3. Restart your device: Sometimes, a simple restart can fix connectivity issues. Reboot your computer, smartphone, or tablet to see if that resolves the problem.
4. Restart your router/modem: If the Internet is working on other devices, you can likely skip this step. But if you don't mind taking a small outage power cycle your router/modem by unplugging it from the power source for about 10-15 seconds and then plugging it back in. This can help refresh the connection.
5. Check firewall or wireless router: Once your Internet modem is back up (Give it a minute or two) reboot your firewall, and wifi router. If they are on separate devices, start with your firewall first. Make sure it comes back up and then reboot your remaining network devices.
6. Disable and enable Wi-Fi: Turn off your Wi-Fi on your device and then turn it back on. This can sometimes refresh the connection and resolve minor issues.
7. Forget and reconnect to the network: On your device, forget the Wi-Fi network and then reconnect to it. This can help establish a fresh connection.
8. Check for software updates: Check and see if any software updates were performed on your device. Sometimes software updates can have unintended consequences and cause connectivity problems.
9. Change DNS settings: Try changing your device's DNS settings to a public DNS server like Google DNS (22.214.171.124, 126.96.36.199) or Cloudflare DNS (188.8.131.52) to see if it improves connectivity.
10. Reset network settings: If the issue persists, you can try resetting your device's network settings to default. Keep in mind that this may remove saved Wi-Fi passwords and other network configurations. (Only do this if nothing else is working)
