WiFi networks in range

[LinuxGuru12]

Hi all -

Is there a utility that, once installed, displays/reports all of the wireless networks within range to your laptop or workstation, and perhaps the strength of it? I just recently built a data server for our home network to manage data and backups in case of failure, and chose to run SuSE on it. Now that it is on a WiFi network, it would be helpful to have such a program.

Thanks,
