I’ve got my wireless setup at home working just fine with my Linux machines (Debian) and for some laptop running Windows 7 could not connect.
The SSID is not hidden (better not to), and still could not find it. I could actually at start see the name of my SSID flashing and disappearing in the list of available network.
Till I discover that this windows could not handle channel number 13… when I changed the channel number of the router, the SSID came in the list.
Great.
