The number of channels available for the wireless LAN adapter (in IEEE

802.11b/g) mode varies by country/region. Refer to the table below to

determine the number of channels available in your location.

If several Wi-Fi devices are operating in the same vicinity, the distance

between the center frequencies of channels used must be at least

25 MHz to avoid interference.
