General Troubleshooting
Check your Wi-Fi connection on your devices. Most internet-connected devices have a symbol that resembles a dot with arching lines on the display to indicate your Wi-Fi connection and strength. The more arching lines displayed, the stronger your Wi-Fi connection. If one device is not getting no or a poor Wi-Fi signal, the problem is most likely with the device. If it is happening on all devices, it is most likely a problem with your internet service. You can find the Wi-Fi symbol in the following locations on the following devices. Windows: In the task bar in the lower-left corner. Mac. In the menu bar in the upper-right corner. Smartphones and Tablets: In the upper-right corner of the screen.
Make sure Wi-Fi is turned on. Click or tap the Wi-Fi icon on your computer or smart device. Check to make sure Wi-Fi is turned on in the Wi-Fi menu.
Check different internet services or websites. If one particular website or app is not working properly, it may be a problem with the app or website. Check other apps and websites to see if you are able to connect to them. If you can connect to other websites or services, the problem is with the website, not your internet connection. If you can't connect to any website or internet service, the problem is most likely with your internet connection.
Check the lights on your modem or router. Most routers and modems have a light labeled "Internet", "WAN" or a symbol of a globe. This light should be solid white or green. If this light is flashing constantly, off, or red, this indicates that your router is not getting a proper signal. The lights on your router may be different from one router make and model to the next. If you are confused as to what the lights mean, check your user's manual or manufacturer's web page for more information.
Make sure your internet cable is firmly attached to your modem or router. Check the back of your modem or router. Make sure your DSL phone line or coaxial cable is firmly connected to the modem or router.
Restart your modem or router. If router settings are as they should detach the power cord from the router, wait for 1 minute and plug it in again. Wait 5 minutes for it to fully boot back up. The lights on the modem or router should turn solid when it is connected to the internet.
Restart your internet-connected devices. Sometimes restarting your internet-connected devices can fix network problems with individual devices.
Move your wireless devices closer to your modem or router. If you find that your devices lose their internet connection when they move away from your modem or router, try moving them closer. If the range or your wireless internet is a problem, you can expand your network using a second wireless router or you can purchase a wireless mesh system to expand the range of your wireless network.
Use a wired connection. A wireless connection is more convenient, but a wired connection is more reliable. If you are having problems with your wireless internet connection, try connecting your computers, game consoles, and smart TVs to your router using an Ethernet cable.
Wait a couple of hours and try again. Sometimes internet traffic can overwhelm your internet service resulting in slow internet speeds and poor connections. Try again in a few hours and see if the issue is resolved. Make a note if you notice internet problems are happening at certain times of the day.
Call your internet service provider. Sometimes problems with your internet connection are the problem with your internet service provider. There may be an outage in your area, or maybe you forgot to pay the bill. Contact your internet service provider to see if there is a known problem with your internet connection, or to report a problem. One last simple fix can be reverting your router back to factory settings.
