Avoid placing wireless components next to large metal objects such as computer 
cases, monitors, and appliances. Metal objects reduce signal strength. 
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.  
If you notice poor connection speed on an adapter, 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. 
Be aware that wireless signal range, speed, and strength can be affected by 
interference from neighboring wireless networks and devices.  
 
 
Adjusting the Antenna 
To improve wireless reception, you can adjust the base station’s external antenna. 
Start with the antenna pointing straight up, and adjust the antenna if you get poor 
signal strength on an adapter. Certain areas, such as directly below the antenna, get 
relatively poor reception. Pointing the antenna toward another wireless component 
does not improve reception.  
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 Base Station 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, this wireless 
base station is compatible with 802.11b devices on your network. 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 base station is not compatible with 802.11a-only devices.
