** Description changed:

  Wifi connection on my Laptop Toshiba S55-A579 with UBUNTU 17.10 gets
  disconnected at random intervals. I noticed this behavior 2 months ago
  and still no solution available. It disconnects at home and even at
- public places. The controller is:
+ public places. Sometimes, when the disconnection happens, the icon of
+ wifi at the top bar transform into a grey box. The controller is:
  
  03:00.0 Network controller: Qualcomm Atheros QCA9565 / AR9565 Wireless
  Network Adapter (rev 01)
  
- I tried some solutions from internet, like setting: wifi.scan-rand-mac-
- address=no and even disconnecting the energy saver feature. Installing a
- firmware that I found in internet: firmware-ath9k-htc_1.4.0-81-gf206e56
+ Setting wifi.scan-rand-mac-address=no, disconnecting the energy saver
+ feature, and installing firmware firmware-ath9k-htc_1.4.0-81-gf206e56
  +dfsg-2_all, doesn't help at all.
  
- Sometimes, when the disconnection happens, the icon of wifi at the top
- bar transform into a grey box.
- 
- It is a very annoying bug, it seems that came with some update, because
- it was working just fine 2 months ago.
- 
- Best.
