Chapter 34 Troubleshooting

VSG1432-B101 Series User’s Guide

I cannot access the Internet anymore. I had access to the Internet (with the ZyXEL 
Device), but my Internet connection is not available anymore.

Your session with the ZyXEL Device may have expired. Try logging into the ZyXEL 
Device again.

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

.

Turn the ZyXEL 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.
