Give your modem and router a quick reset (that is, turn them off and on again) and see if that helps. Check the other computers in your house to see if their internet is slow, too—if the problem only happens on one computer, the problem is that computer, not your router or modem. Run through these troubleshooting steps to see if it’s a hardware problem. Then, once you fix your router or modem (or replace it), you’ll be browsing speedily once again. Check out our complete guide to knowing your network for more router tips, too.
