Hello, these logs are produced with NetworkManager (i connected using network manager). The only log that was produced with wpa_supplicant only is wifi.log where u can see the wpa_supplicant command arguments. The NetworkManager was stopped with systemctl stop (however I did not use systemctl mask, but from what I've checked, there was no network manger shown in process list). I will try to redo the test with NM masked. Btw, I tried a Fedora 22 livecd and there were no disconnects at all (it has new wpa_supplicant 2.3.3, here I have 2.1), however the max connection speed I saw there was 300mbps. Here on Ubuntu Vivid i see speeds up to 620mbps (and in Windows 7 I have 866mbps).
