Wireless network analyzers can come in many forms. One type has integrated functionality in wireless routers or access points. Figure 11.1 below illustrates the wireless network discovery functionality in a DD-WRT SOHO router:

The information presented in the status table above includes:
- SSIDs
- MAC Addresses
- Channels used
- Transmission rates and the 802.11 protocols used
- Other Wi-Fi parameters (e.g., noise, beacon, etc.)
Another way of representing the same information is in graphical format, as presented in Figure 11.2 below. With this format you can identify the access points (SSIDs) and the wireless clients associated with them.
