Wireless Troubleshooting

Back

Items that can cause interference with Wi-Fi connections include:

  • Ceiling fans
  • Washing machines
  • Clothes dryers
  • Cordless phones in the 2.4 GHz frequency
  • Certain home security equipment
  • Monitors (ie. Baby monitors)
  • Electric heaters
  • Microwaves
  • Dishwashers (to a lesser extent)
  • Other items that can cause RF “noise”

Note:The interference occurs during the operation of the appliance. When the appliance is turned off, the Wi-Fi connection should be stronger due to a drop in radio interference.


Troubleshooting Tips:

  • Keep your antenna at least 6 inches away from the wall or other objects
  • Be sure the PC card antenna is not pushed behind or under furniture, desks, etc.
  • If using a desktop PC, consider purchasing a USB Wi-Fi PC card. The USB cable is usually about 6 feet in length. This allows for the antenna on the computer to be relocated in order to establish a stronger connection.
  • Be sure you have configured the network card to the proper SSID and channel. (Call the helpdesk for the best settings to use for your network card.)
  • Call the Roanoke College Helpdesk if you continue to have problems or questions at 375-2225.
