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.
