On my home unit, it often associates on the first try and ALMOST always on the second. With the hotspot on my Galaxy S5 phone, it almost never associates on the first try and usually takes three or four tries, but I keep seeing "link state changed to UP" messages followed by "link state changed to DOWN". Over s single second I logged an UP followed by in a row followed by three cycles of UP and DOWN in one second and an UP that actually was UP. the next boot I got 4 UP/DOWN cycles (no double UP) but it gave up at this point. Then I did a "netif restart wlan0" and ti came up. Next boot had 8 UP/DOWN, but never actually appeared to associate. I am not seeing symptoms of the wpa_supplicant issue. The sample I included in the original message had the only repeat wpa_supplicant message. It is certainly not behaving like it did the last time I saw the that issue. None of these problems were seen with 10.3. -- R. Kevin Oberman, Network Engineer E-mail: kob6558@gmail.com
