“WiFi Radar is a handy tool for those who move from one wireless
access point (AP) to another. My laptop regularly connects to a
wireless AP on my home LAN, to a free wireless service in downtown
Austin where we hold our weekly LUG meetings, and to whatever is
available at airports and hotels when I’m on the road. WiFi Radar
makes it simple to switch connections no matter where I am.“The software is available in pre-packaged form for Gentoo,
Debian, Ubuntu, and SUSE distributions. You can also get the latest
tarball from the WiFi Radar homepage…”
