Hi there,

You can call the call center for remote assistance, or bring the device to a Samsung Service Center to have it checked out.

Hi, please check wheather your wifi is working well on other devices. If fine, you can try after resetting the network settings.(Settings > General management > Reset > Reset network settings) Please note that this will reset all your wifi and bluetooth settings. Thank you.
