ClassicStumbler scans for and displays information about all the wireless access points in range. It will display your signal strength, noise strength, signal to noise ratio, what channel your access point is on, if other access points are interfering with yours, and whether or not those access points are providing encrypted, unencrypted, computer-to-computer, or infrastructure type networks.
