In fact, just "iwlist scan" returns the same result - only the info for my AP is returned.

(10 times, followed by 1 __ratelimit: 2 callbacks suppressed (then 10 more frame lost messages, and so on) The number in "callbacks suppressed" varies pretty widely, from 2 to 32. > Yeah a lot of APs will stuff a ton of info into the IEs these days, > including WPS, WPA, 11d, blah blah.
