VMG1312-B10A User’s Guide

Check the hardware connections, and make sure the LEDs are behaving as expected. See the 
Quick Start Guide and 

Turn the Device off and on.

If the problem continues, contact your ISP. 

What factors may cause intermittent or unstabled wireless connection? How can I solve this 

problem?

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 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.

What wireless security modes does my Device support?

Wireless security is vital to your network. It protects communications between wireless stations, 
access points and the wired network.
