I am experiencing unexpected signal strength values reported by an AR9280. Basically, they always tend to be flat no matter how far or close I am from the device that is transmitting. Roughly between the -65 and -55dBm range on average. The exact AR9280 I am using is: Sony UWA-BR100 802.11abgn Wireless Adapter [Atheros AR7010+AR9280] I have compared this behavior to a bcm4322 and the behavior I see with the bcm4322 is as expected. Far away I get low signal strength values, and close to the device I get high signal strength values (-20dBm). Here is a comparison of the two (taken at the same time) as I walk closer to the transmitter. I record the signal strength from wireshark using radiotap header field radiotap.dbm_antsignal. http://www.flickr.com/photos/gnychis/7203437510/in/photostream Surprisingly, the average signal strength seems to decrease with the ar9280 as I get closer, yet remains relatively flat. The bcm4322 shows a clear increasing trend as I get closer. Does anyone have any insight as to what might be going on? I'm using the most recent firmware and compat-wireless as of May 14, 2012.
