Hi Javier, As far as the kernel, configurations and environment, we conducted the tests with the same setup. We follow exactly like what is mentioned in the HOWTO. Eventhough the environment is not 'quiet', we did our test by using conducted testing.
Open MESH results are okay (the Rx Signal Strength is about -10 dBm consistently). For SAE, we noticed that the Rx signal strength fluctuated, from 2dBm until -70dBm. It's a huge fluctuation there. It was observed on all WLAN cards that we used (all based on Atheros chipset). That resulted into the bitrate seen fluctuated as well, at times didn't make it to the endpoint. So, we are wondering what would make the fluctuation to happen. Is it something to do with the wpa_supplicant <-> driver relationship or anything else that could be the real disturbance?. Appreciate your input. Thanks. Rgds, Zaki.
