You're at home and notice that the internet seems to be out whenever you try to connect to a website on your laptop.
You have already tried turning the wifi router on and off again already, but with no luck.
Now it is time to check other possible causes.
- Local network connection
- Internet Service Provider (ISP)
- Local router
What to do?
Open a terminal or command prompt if you're on windows and use PiNg to check if any website is reachable,
www.google.com is a common choice.

If you didn't see something like above then chances are you received one of the following:
Error Messages and Meaning
No reply from www.google.com
- The destination routes are available but that there is a problem with the destination itself
- The server(s) are down at the website you're trying to visit
- Need to wait for them to be 'alive' again
www.google.com is unreachable
- Indicates that your host doesn't know how to get to the destination, so that means either that the routing information to reach another subnetwork is not available or that the device on the same network is down
- Either the subnetwork is inaccessible due to IP restriction or the device on the network is down
- Check if the device by using traceroute
ICMP host unreachable from gateway
- Your host can transmit to the target address via a gateway, but the gateway cannot forward the packet properly because a route or gateway is misconfigured at your ISP or geolocation
- Call your ISP provider and ask them what the deal is
Request timed out
- The reply took to long from the destination server
- Probably a firewall blocking traffic from your IP address
- Meaning you don't have access to that site
