** 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:
  
  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
  +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.

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. 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+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.
