WiFi connection

[BM4]

My WiFi is connecting to my tablet and I can use the Internet on that device but when I try my mobile devices it just says "connected with no internet". I have tried troubleshooting multiple times and it says it should be working but it's not, I'm not sure what the issue is but I would appreciate any help if someone could advise me on what to do.

@BM4   Delete the Wi-Fi connection from your device and restart the router once started try adding your device to the Wi-Fi connection.   Turn the router off for around 30 seconds. It wouldn’t hurt to restart your device when the router is off.
