Observe Wireless Location and Range Guidelines
For best performance, place the wireless USB adapter at least 4 feet (over 1 meter) away from the wireless router or access point.
Computers can connect over wireless networks indoors at a range that varies significantly based on the physical location of the computer with the wireless USB adapter. For best results, avoid potential sources of interference, such as the following:
•Large metal surfaces
•Microwaves
•2.4 GHz or 5 GHz cordless phones
Note: If there is 2.4 GHz interference at your location, such as from a cordless phone, you 
can change the setting to 5 GHz for better wireless throughput. See “Advanced
Settings” on page 2-17.
In general, wireless devices can communicate through walls. However, if the walls are constructed with concrete, or have metal, or metal mesh, the effective range decreases if such materials are between the devices.
