The WiFi connection is slow and intermittent.
The following factors may cause interference:
• Obstacles: walls, ceilings, furniture, and so on.
• Building Materials: metal doors, aluminum studs.
• Electrical devices: microwaves, monitors, electric motors, cordless phones, and other WiFi devices.
To optimize the speed and quality of your WiFi connection, you can:
• Move your WiFi device closer to the AP if the signal strength is low.
• Reduce WiFi interference that may be caused by other WiFi networks or surrounding wireless
electronics such as cordless phones.
• Place the AP where there are minimum obstacles (such as walls and ceilings) between the AP and
the WiFi client.
• Reduce the number of WiFi clients connecting to the same AP simultaneously, or add additional APs if
necessary.
• Try closing some programs that use the Internet, especially peer-to-peer applications. If the WiFi client
is sending or receiving a lot of information, it may have too many programs open that use the
Internet.
• Place the Zyxel Device where there are minimum obstacles (such as walls and ceilings) between the
Zyxel Device and the wireless client. Avoid placing the Zyxel Device inside any type of box that might
block WiFi signals.
