There are usually two places to look if you are facing network issues —
1. Router
2. Device having the issue
If the Internet is not working on all the devices connected to the WiFi network, then chances are there is a problem with your router/modem. You can also look at ADSL cable to see if it’s broken or twisted.
If the Internet is not working on only one device but working fine on other devices connected to the same network, then chances there is an issue with the device’s WiFi adapter or the Routers and that particular devices are having a hard time to communicate.
Solution how to fix, WiFi Connected But No Internet Access :
1. Restart Devices - Turn off both router and modem (if they are separate) and wait for 30 seconds before restarting them again. Additionally, you should also restart your PC to ensure things are clean. Once all the devices are reset, try connecting again to see if it works.
2. Check Modem Lights - There might be a problem with your internet connection instead of the devices connected. The DSL lights should be ON (or turn green in some routers), and the WiFi indicator lights should blink. If you are not sure how to check, contact your ISP customer care services. If you are not sure how to check, contact your ISP customer care services.
