Solve problems limiting your wireless network signal.

Strengthen Your Connection

Does your wireless Internet connection seem slower in some areas of your house, or slower than your wired connections? Household objects such as furniture and other wireless networks could be weakening your signal. If you think your connection is too slow, there are a few simple placement changes you can make to potentially boost the wireless signal. Here are some helpful tips to ensure that you’re receiving the strongest wireless signal possible.

Place Routers Carefully

The location of your wireless gateway or router can greatly affect your wireless network’s performance, as some common household features such as walls can block the signal. Follow these guidelines when choosing the right spot:

  • Place routers high up and clear of obstructions – in general, an open space is better than a crowded one. If you have the Wireless Gateway 1 (model number TG852G, TG862G, SMCD3DNV, or TC8305C) or Wireless Gateway 2 (model number DPC3939), it should be placed in an upright position.
  • Avoid placing routers within two feet of metal objects like pipes, reinforced concrete, or metal partitions—as well as within metal enclosures like bookshelves or cabinets—as they can cause interference.
  • Avoid placing routers near large amounts of water like fish tanks and water coolers, which can diffuse and weaken your signal.
  • Avoid placing routers near windows, as they allow outside interference into your home.

Reduce Electromagnetic Noise

Your router can be affected by noise from nearby electronic sources. Place your wireless gateway or router away from:

  • Cordless phones.
  • Computers and fax machines (by at least one foot).
  • Copying machines, elevators and cell phones (by at least six feet).
  • Microwave ovens (by at least 10 feet).

Note: This is only a partial list. Other electronic items may also cause interference with your Wi-Fi network.
