Spotty WiFi can be extremely frustrating. The issue may stem from your service provider, your computer, your router, or even your environment.
Before you throw your computer across the room in a rage, confirm that it’s within range of your wireless router. You should also make sure your WiFi is turned on and Airplane mode is turned off. On a Windows PC, select the “No internet connection” icon on the right side of the taskbar and make sure the WiFi is turned on.
You can also try connecting to a WiFi network on a different frequency band. Many routers broadcast at two frequencies, 2.4GHz and 5 GHz, which appear as separate networks on the list of available WiFi networks.
If that doesn’t work, you can also run the network troubleshooter to help diagnose and fix common connection problems.
