First, rule out simple fixes:

Restart your tablet. Often, a reboot refreshes connections and clears minor glitches.

Turn the Wi-Fi on and off. Double-check that the Wi-Fi toggle isn't stuck and reconnect.

Move closer to the router. Distance matters! Signal weakens with walls and interference.

Next, check your network:

Confirm if other devices connect. This isolates the problem from your tablet.

Restart your router and modem. A quick power cycle can resolve network issues.

Check if your network is hidden. You might need to manually enter the SSID and password.

If that fails, delve deeper:

Forget and reconnect to the Wi-Fi network. This removes saved login data and forces a fresh connection.

Update your tablet's software. Outdated software can cause compatibility issues.

Reset your tablet's network settings. This is a last resort, as it erases all Wi-Fi passwords.

Still no luck?

Consult your tablet's manual or manufacturer's support. They might have specific troubleshooting steps.

Consider professional help. A technician can diagnose hardware issues or complex network problems.
