Some of the channels in the scanner options window are grayed out. Is this normal? What if I want to monitor these channels?
The answer depends on the adapter type:§ Atheros-based CardBus, PCI, miniPCI, miniPCIe, and ExpressCard adapters: Depending on your country, your wireless adapter may not support all the channels shown in that window. The channels that are available for use in a particular country differ according to the regulations of that country. In the United States, for example, FCC regulations only allow channels 1 to 11 to be used in the 802.11b/g/n band. The firmware of the wireless adapters being sold in the US is typically configured to disallow channels 12 and 13.

  • Atheros-based USB adapters: All channels are always available when using them in TamoGraph.
  • Non-Atheros adapters (e.g. Intel, Dell, or Broadcom): enabling channels 12 and 13 may be possible through some configuration changes. Contact us if you need assistance.
