[Sander Brandenburg <sander.brandenburg@xxxxxxxxx>]

1/ Compute model:
It's a custom built PC I assembled recently, using a 'Cooler Master Elite 120 Advanced' case. I suppose it is not overheating, although I very much so distrust the sensors output now I look at it:
ubuntu@ubuntu:~$ sensors
radeon-pci-0008
Adapter: PCI adapter
temp1:         +2.0°C  (crit = +120.0°C, hyst = +90.0°C)

k10temp-pci-00c3
Adapter: PCI adapter
temp1:         +2.8°C  (high = +70.0°C)
                       (crit = +70.0°C, hyst = +69.0°C)

2-2.8 degrees cannot be achieved by just some case fan running silently.

2/ I'll try updating the bios from 2.0 to 2.3 after this test run. The changelog does not look promisary:
Description 	- Improved PS2 KB/Mouse compatibility. Version 	2.1
Description 	- Update BIOS module.	Version 	2.2
Description 	- Update BIOS module.	Version 	2.3

3a/ AP:
Belkin F7D2301 Belkin Surf
firmware: 	1.00.16 (Jul 2 2010 14:36:56)
Updates are not available. 
Unfortunately it's not supported by ddwrt/openwrt :/

3b. What wireless connection type are you using: 802.11g

4/ I will fidget with my AP settings later.
5/ No
6/ 3 meters
7/ A big metal structure is in between (a big stove) 
7a/ Don't know yet
8/ I have only one AP right now
9/ I've only tried out saucy and trusty


The connection looks strong:
wlan0     IEEE 802.11bgn  ESSID:"XXXXXXXXX"  
          Mode:Managed  Frequency:2.462 GHz  Access Point: 94:44:52:24:A3:2C   
          Bit Rate=54 Mb/s   Tx-Power=20 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality=58/70  Signal level=-52 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:1557  Invalid misc:73   Missed beacon:0

However, I'm sure that the Belkin AP may induce any kind of crappiness.

It takes quite a few hours until I know whether the situation has improved. However, I'm clueless what kind of internal error the wireless device is encountering. 
In trusty it appears that the deauth messages have changed the reason from 3 to 6 and 15.

Title:
  0cf3:9271 [MSI FM2-A75IA-E53] ath9k_htc: AR9271 wireless device stops
  functioning

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  A long time after a cold boot, my wireless connection starts dropping,
  will try to reconnect but will not come back again. When I'm in that
  state only a suspend, waiting a while and resuming gets my wireless
  connection back again.  However, after that state it does not take
  long before it starts to drop again.

  WORKAROUND: I could not reproduce this problem again after setting
  nohwcrypt=1 on the ath9k_htc module.
