  8. Troubleshooting Internet Connection Problems • The obvious: unplug modem and router, wait, and plug back in. This solves a majority of connectivity issues. • If you recently installed software, make sure installation was successful. • Run a ping command – the command sends a message to the web server. Howtogeek.com has tutorials for running this command. • Use the Down For Everyone Or Just For Metool to determine if the problem is with the website. • If all else fails, call internet service provider.
