Most everything these days is .11b/g or b/g/n compatible. In various countries, there are different allotments of how many 2.4Ghz 'channels' are available for unlicensed use like wifi. see http://en.wikipedia.org/wiki/IEEE_802.11#Channels_and_international_compatibility for a summary of this specific issue. my general experience regarding all this is the business model laptops from the major makers (for instance, the Latitudes from Dell) tend to come with wifi (and modems etc) that support multinational standards that can be reconfigured for different locales. consumer grade stuff is less likely to have this ability enabled. -- john r pierce N 37, W 123 santa cruz ca mid-left coast
