WLAN Freeware Wifinian: Free Tool Optimizes Your Wireless Network
Wifinian calls himself the little free helper who promises you the best possible internet connection. The tool scans all WiFi networks in the environment at an interval that you specify and sorts them according to the signal strength. Practical: This is displayed not only in the usual bar form, but also in the form of a more precise percentage.
If you would like to set your own priorities for the WLAN connection, you can use the "Reorder" function to change the order of the Change networks. When automatically connecting to a network, Wifinian then considers both the signal strength and the priorities set. This is especially useful if you want to connect to a network that has the lower signal strength but more bandwidth.
