The NO-IR flag then means you cannot use modes of operation that require you to initiate radiation first, there are two ways that can happen: * beconing -- AP, IBSS, Mesh, P2P master mode * active scanning You are still able to do passive scanning. The NO-IR flag can be lifted from channels if the driver does like the idea of trusting beacon hints: http://wireless.kernel.org/en/developers/Regulatory/processing_rules#Beacon_hints If the driver does not like those then you won't get the NO-IR flag lifted when a beacon is found. There device follows the desire by the silicon manufacturer and whoever deploys the device and integrates it into your system so anything beyond this should be checked with Intel folks.
