As shown in
Figure 13-9, you should see the connection and activity status. This lets you know the network name (SSID) you are connected to, how long you have been connected, the speed (or data rate), and the signal strength of the connection. You can also see how many packets have been sent and received while you have been connected.

If both the wireless network adapter you are using and the wireless router or access point are 802.11g-compliant, the best possible data rate would be 54 Mbps. When you are using products with a speed-booster feature, the data rate might be higher. If the network devices, however, support only 802.11b, the highest data rate possible is 11 Mbps.
In addition, this window gives you another way to disable your network adapter, go to the properties of the adapter, and go to the View Available Wireless Networks window.
