The default is to use the 'world' regulatory domain, not the US domain. This still allows scanning for and using an AP on all channels; it just doesn't allow transmissions above channel 11 until an AP is found. However this might be overridden based on the country setting of the wireless network adapter. Or a particular driver might not implement the regulations correctly. Please specify what wireless network adapter you are using (if it's something built in and you don't know, lspci or lsusb will help to identify it). Also please provide the system log from the installer. Ben. -- Ben Hutchings You can't have everything. Where would you put it?
