arty, thank you for reporting this and helping make Ubuntu better. Could
you please advise if the firmware of your router is the latest Version
(1.01.009) as per
http://hilfe.telekom.de/hsp/cms/content/HSP/de/3388/FAQ/theme-293811306/Speedport-W
-723V-Typ-A ?

If not, could you please update it to it, and advise if this changes
anything?

** Description changed:

- My problem seems to be different from #1315221 because it exists in
- 3.16.0-28-generic (Ubuntu 14.10). It is also different from #1405298
- because it happens with the latest BIOS upgrade. dmidecode returns
- version A11 and date 12/03/2014
- 
  About every 10 minutes my WiFi disconnects and a line like this appears in syslog:
  Dec 24 11:31:31 work kernel: [ 2721.017478] wlan0: deauthenticated from 10:c6:1f:2c:49:56 (Reason: 7=CLASS3_FRAME_FROM_NONASSOC_STA)
  
  It is accompanied later by such line:
  Dec 24 11:31:46 work NetworkManager[902]: <info> (wlan0): device state change: activated -> failed (reason 'SSID not found') [100 120 53]
  
  The network disappears from the list and only becomes visible after I
  disable and re-enable networking via the network applet.
  
  I don't remember seeing this problem at work where they use Cisco
  routers. I see the problem at home with my Speedport 723V Typ A router
  (a+b+n mode, WPA2). This may be affected by number of other wifi
  networks which are visible here: at least 17 at the moment.
