[UbuntuGnome] Acer Aspire v 15 v3-575T-7008 wifi networks do not show up -Gnome 16.04 BETA 2

Hi,

There is no soft or hard lock for wifi as confirmed by

sudo lshw -C network

I have installed Gnome 16.04 BETA 2 ,now it does not show available WiFi networks.

nmcli -p r

above command shows all wifi related radio switches enabled

Please suggest

sudo modprobe ath10k

above command shows
modprobe:FATAL:Module ath10k not found in directory /lib/modules/4.4.0-15-generic
