Testing the Modem

• 1). Shut down your computer and reboot your wireless modem, or gateway, by pressing the "On" button --- located on the back of the modem --- to turn it off. Leave your wireless modem and your computer off for about 10 seconds, then turn them back on and try to re-establish a connection.
  
  
• 2). Check the range and placement of your wireless modem --- too many walls or ceilings can limit broadcast of the signal.
  
  
• 3). Position your modem, if possible, near open doorways and drywall. This will allow the signal to pass through easily. Avoid positioning your modem near metallic objects (such as door frames) or concrete walls --- concrete is reinforced with steel.
  
  
• 4). Position the modem's antenna(e) upward for better reception.
  
  
• 5). Keep your modem away from electrical devices like monitors, computer speakers and electric motors that generate radio frequency (RF) noise.
