Network issues with wifi

Dear Samsung member,

Greetings from Samsung customer support.

Thank you for sharing your concern. We acknowledge your query and apologize for the same. And please follow the easy troubleshooting steps which might help to solve the issue.

Step1: Navigate to apps screen and tap on Settings.
Step2: Tap on Connections.
Step3: Tap on Wi-Fi.
Step4: Tap on Wi-Fi network.
Step5: Tap and hold the Wi-Fi network that you're having trouble with until the menu allows you to select Forget Network.

Switch off your Router (at the wall or with the power button on the router) and wait for 2-3 minutes before switching it on. While you're waiting, press the Power button on your mobile device and select Restart.
Once the router has been successfully connected to the internet again, try to connect to your network on your mobile device.
Make sure there is no interference between the router and your mobile device. Concrete walls, fridges, and microwaves can all interrupt the Wi-Fi signal.

In case the issue still occurs. Please register your concern in Samsung Members Application (Open Samsung Members Application > Support> Tap on error report > Type your query > Send).

Thank you for writing to Samsung.
Warm regard,
Samsung customer support
