Scan the Wi-Fi networks around you and track their signal strength over time inSSIDer scans all the Wi-Fi networks within the reach of your computer’s wireless card, tracks their signal strength over time, and determines their security settings. Track open or secure wireless networks. Determine the best channel for your own wireless network. Use the Networks Table to view all nearby access points and their details. See Received Signal Strength, Security, Channel, Hardware Vendor, Max Rate, Network Type, and MAC Address for each access point.
