Wireless Network Considerations
Intel WiFi Link 5300 device supports IEEE802.11a (infrastructure mode only), IEEE802.11b,
IEEE802.11g, and IEEE802.11n.
The WLAN device operates in the 2.4 GHz ISM band and the 5 GHz lower, middle, and upper UNII
bands.
Microwave ovens may interfere with the operation of WLAN devices since they operate in the same
2.4 GHz frequency range as IEEE802.11b/g/n devices. Interference by microwaves does not occur
with IEEE802.11a radio which operates in the 5 GHz RF band.
Wireless devices that transmit in the 2.4 GHz range may interfere with operation of WLAN devices
in IEEE802.11b/g/n modes. Symptoms of interference include reduced throughput, intermittent
disconnects, and many frame errors. It is HIGHLY recommended that these interfering devices be
powered off to ensure proper operation of the WLAN device.
Deactivating/Disconnecting the WLAN Device
Deactivation of the WLAN device may be desired in certain circumstances (to extend battery life) or
where certain environments require it (i.e. hospitals, clinics, airplanes, etc.).
BEFORE USING THE WIRELESS LAN DEVICE, YOU MUST FIRST INSTALL CLICKME! TO ENSURE THAT THE
CORRECT SOFTWARE FOR YOUR DEVICE IS INSTALLED. SEE “INSTALLING CLICK ME!” ON PAGE 56.
