Notes on Using the Wi-Fi FunctionUse of Wi-Fi devices may be restricted by local regulations in some countries or regions.Wi-Fi devices work on the 2.4 GHz band, which is used by a variety of devices. Wi-Fi devices therefore usetechnology to minimize radio interference from other devices that use the same band. However, radiointerference may still cause slower data transfer speeds, reduce communications range or causecommunications failure.If both the Bluetooth function and the 2.4 GHz Wi-Fi function of your tablet device are enabled, interferencemay occur and cause slower data transfer speeds or other problems.To communicate via Wi-Fi while traveling, you may need to contract with a Wi-Fi connection service provider.Data transfer speed and communications range may vary depending on the following conditions:Distance between devicesPresence of obstacles between devicesDevice configurationSignal conditionsSurrounding environment (wall material, etc.)Software in useCommunications failure may occur in some signal conditions.The data transfer rate noted in the specifications is the theoretical maximum, and it may not reflect actualdata transfer rate.Actual data transfer speed may not be as fast as the speed displayed on your tablet device.Communications is not available between the 2.4 GHz and 5 GHz Wi-Fi frequency bands.The data transfer rate for IEEE 802.11g and IEEE 802.11n (2.4 GHz) devices may be affected by interferencewhen those protocols are used with IEEE 802.11b products. Also, products using IEEE 802.11g and IEEE802.11n automatically lower the transfer rate to maintain compatibility with IEEE 802.11b products.When the data transfer speed is not as fast as expected, changing the wireless channel on the Wi-Fi routermay increase the speed.Related TopicSpecifications
