What's wide 9? HT40 with the primary channel on 11 and the extension on 6? > The access point is a Linksys wrt120n (probably not the best, I know). Isn't this a 1-stream align-n (AR9285) platform? If so then there is no advantage of using an AR9170 over the AR9271. > To be honest, I don't know what a TSF is or how to check it. The TSF keeps the timers for all STAs in the "network" synchronized. http://en.wikipedia.org/wiki/Timing_Synchronization_Function_%28TSF%29 It can be easily check by: iw dev wlanX scan e.g.: (sample output) BSS 00:02:32:0d:d1:32 (on wlan13) TSF: 2669831323 usec (0d, 00:44:29) <------- freq: 2437 This will tell you that the "network" has an uptime of 0 days, 0 hours, 44 minutes and 29 seconds.
