If you cannot access a network folder, make sure your account has access rights to the folder you 
are trying to open.
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. 
• Position the antennas for best reception. If the AP is placed on a table or floor, point the antennas 
upwards. If the AP is placed at a high position, point the antennas downwards. Try pointing the 
antennas in different directions and check which provides the strongest signal to the wireless 
clients.
