O
Avoid placing wireless components next to large metal objects such as computer 
cases, monitors, and appliances. Metal objects reduce signal strength. 
O
Avoid placing wireless components close to electromagnetic devices, especially 
those with frequencies in the 2.4-gigahertz (GHz) range. Devices such as cordless 
phones, microwave ovens, radios, and televisions can interfere with wireless 
transmission.  
O
If you notice poor connection speed in an area, try moving your wireless 
components closer together. Connection speeds will be slower if your wireless 
components are very far apart from each other on the network. 
O
Be aware that wireless signal range, speed, and strength can be affected by 
interference from neighboring wireless networks and devices.  
 
Understanding Wireless Transmission Standards 
802.11 is a series of wireless transmission standards developed by the Institute of 
Electrical and Electronics Engineers (IEEE) for wireless local area networks. Currently, 
four specifications make up the 802.11 series: 802.11, 802.11a, 802.11b, and 
802.11g. Your Microsoft Wireless Notebook Adapter conforms to the latest 
specification, 802.11g. The main features that distinguish these specifications are 
connection speed and radio frequency.  
The following table summarizes the four specifications in the 802.11 series. 
 
Specification 
Connection speed 
Radio frequency band 
802.11 
1 or 2 megabits per second (Mbps) 
2.4 GHz 
802.11a 
Up to 54 Mbps 
5 GHz 
802.11b 
5.5 and 11 Mbps 
2.4 GHz 
802.11g 
Up to 54 Mbps 
2.4 GHz 
 
   
Note   The benefit of the 2.4-GHz radio frequency band is that it allows for greater range 
than the 5-GHz band. The drawback is that it is susceptible to interference from other 
devices such as 2.4-GHz cordless telephones.  
Because 802.11b and 802.11g use the same radio frequency band, your 802.11g 
adapter is compatible with 802.11b devices. However, when you transfer data 
between 802.11b and 802.11g devices, the connection speed is limited to the 
802.11b maximum of 11 Mbps.  
   
Note   Your Microsoft Wireless adapter is not compatible with 802.11a-only devices.
