Samsung Galaxy S III™ - Can't connect to a Wi-Fi network

Make sure your smartphone has been set up to connect to Wi-Fi

  • Learn how to connect to a Wi-Fi™ network.

Verify a Wi-Fi signal is available

If you're having trouble picking up a Wi-Fi signal, the problem may be originating with the network, not your smartphone. To determine this, check whether other wireless devices, such as a laptop computer, can connect.

Check your location and surroundings

Wi-Fi signals can be weakened by certain building materials, such as concrete or steel, or disrupted by electronics, such as televisions or stereos.

To ensure that your Wi-Fi signal is not compromised, we recommend that the following objects not be located within 8-10 feet of your wireless router or gateway:

  • Televisions
  • Stereo or Computer Speakers
  • Cordless Telephones and Stations
  • Other Routers
  • Computer Monitors or Tower
  • Bluetooth Devices
  • Microwaves

We also recommend that your wireless router or gateway be placed on an elevated surface such as a table or shelf in order to maximize the range of your Wi-Fi signal.
