Position Your Gateway

The operating distance or range of your wireless connection can vary based on the physical

placement of the gateway. For best results, place your gateway:

•

Near the center of the area in which your computers operate.

•

In an elevated location such as a high shelf.

•

Away from potential sources of interference, such as computers, microwave ovens, and

cordless phones.

•

Away from large metal surfaces.

Note:

Failure to follow these guidelines can result in significant

performance degradation or inability to connect wirelessly to the

modem router.
