EMG2926-Q10A User’s Guide

• 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.
