Dropping wifi Ubuntu 14.04: Reason: 7=CLASS3_FRAME_FROM_NONASSOC_STA

**Joost_Plas** · July 16th, 2015

Hi guys,

I'm having some annoying wifi problems.
I run a pretty minimal Ubuntu 14.04.2 server installation with LXDE (mostly based on this guide: http://thepcspy.com/read/building-a-...u-1404-chrome/)

I run this on a Gigabyte Brix GB-BXCEH-3205.

I'm having some annoying wifi connection problems. I've tried this both with the internal wifi adapter and with a external one: TL-WN722N.
The problem is that regularly I cannot connect from other machines to the Brix anymore. I try this with SSH. Usually when I leave the machine alone for a few hours and try to connect I have no access through SSH and I also don't see the machine when I do a scan of my network. When I enter the terminal on the Brix and try 'ping www.google.nl' it always works. After that I can also again connect from the outside to the machine again.

I get a lot of 'deauthenticated' messages in my syslog. Seems related, but so far I could not prove the relation 100% by looking at the times.

I tried to add a lot of debug info. This is all with a working internet connection at the moment, but problems earlier this day (around 14.42 in log).
Any help would be much appreciated. It is crippling my setup.

the same problem here, look:

It seems to be a suspend / idle issue.
When I leave my system idle (no suspend, power management is disabled) for a while I cannot connect from the outside anymore.
I can 'fix' this by just plugging in a keyboard and mouse on the remote machine and open a terminal. After that the connection from outside works again. I don't even have to activate the network or ping something, it just works.

Any tips how to prevent this?

I know this thread is several months old now, but I may have a solution that others will find useful. I was having the same problem with intermittent wireless disconnects and seeing "Reason: 7=CLASS3_FRAME_FROM_NONASSOC_STA" in the syslog. What I ended up doing was disabling power management for the wireless adapter. Afterwards, the disconnects stopped. I'm running Linux Mint 17.2 with an Intel Wireless 3160 adapter.

To check if power management is enabled just issue: iwconfig
Look for the output: Power Management: on
The command to disable power management is: sudo iwconfig wlan0 power off

You can create a script in /etc/pm/power.d/ that will disable power management upon boot. Add the following to your favorite text editor and save it as "wireless" in /etc/pm/power.d/wireless

Code:
