** 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

Title:
  [Toshiba Satellite S55-A579] Wifi disconnects randomly under ubuntu
  17.10

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  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. 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)

  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.
