What if Samsung's mobile phone is connected to the wireless network but can't be used?

If the mobile phone shows that it is connected to the wireless network, but it still cannot access the Internet, it is suggested that:

1. Turn off and restart the phone, reset the router, and then reconnect the wireless network.

2. Please confirm the transmission bandwidth of the router (the bandwidth supported by the router supporting 802. 1 1n is 40mhz, and it is recommended to set it to 20mhz), and then confirm whether the router network is normal.

3. Confirm whether IP address filtering /MAC address filtering is set in the router.

4. If you still can't access the Internet through WLAN, it is recommended to try using static IP. Mode: Settings-(Connect) -WLAN- Select Wireless Hotspot-Show Advanced Options-Check-Slide Down the Screen -IP Settings-Static -IP Address/Gateway.

5. Try connecting other routers.

6. Try to restore the factory settings after backing up the important data of the mobile phone.

If the problem still exists, it is recommended to bring the purchase invoice, three-guarantee certificate and mobile phone to Samsung service center for inspection by engineers.
