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.
