WiFi: Frequent wlan0 deauths with Reason 2 and Reason 15

Official Hardware Classic Yún
1

My Yun's wifi is intermittent. It does work for a bit, and then it doesn't... probably because it starts to disconnect/reconnect over and over again. This is a WPA2 network. Anyone know what this is?

UPDATE: I noticed that it auths at two different MAC addresses:
Dec 11 11:27:58 Arduino kern.info kernel: [ 1739.130000] wlan0: send auth to 20:3a:07:33:ba:00 (try 1/3)
then later it will deauth and do this...
Dec 11 11:31:03 Arduino kern.info kernel: [ 1924.950000] wlan0: send auth to c0:25:5c:97:6a:b0 (try 1/3)

UPDATE: Even when I specify a certain BSSID (Mac address) it will deauthorize with either Reason 2 or Reason 15 and then reauthorize. So now I'll have to focus on the events that look like:

I have exactly the same problem : Wifi Yun trouble - Arduino Yún - Arduino Forum
I will keep you informed if I found the solution :slight_smile:

3

Actually I'm getting Reason 2 and Reason 15 but it from the log you posted, yours is different...

I've seen explanations of Reason 2 and 15 from kernel bugs to wpa_supplicant.conf config issues (password?) but nothing I know how to address easily.

I did find that on the Linux stack that file is /tmp/run/wpa_supplicant-wlan0.conf

4

Here's what it does when I tell it to only use a particular BSSID. The password is correct as a checked it with another device.
