• Building Materials: metal doors, aluminum studs.
• Electrical devices: microwaves, monitors, electric motors, cordless phones, and other wireless 

devices.

To optimize the speed and quality of your wireless connection, you can:

• Move your wireless device closer to the AP if the signal strength is low.
• Reduce wireless interference that may be caused by other wireless 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 wireless client. 

• Reduce the number of wireless 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 

wireless client is sending or receiving a lot of information, it may have too many programs open 
that use the Internet. 

What is a Server Set ID (SSID)?

An SSID is a name that uniquely identifies a wireless network. The AP and all the clients within a 
wireless network must use the same SSID.

If you are connecting a USB hard drive that comes with an external power supply, make sure it is 
connected to an appropriate power source that is on. 

Re-connect your USB device to the VMG.
