wifi cannot find any network

[Guilherme Bezerra dos Santos]

I tried to use this command to try to solve the problem, but it didn't work: sudo service network manager and tried to update the system and restart the machine.

Thank you for your bug report, that seems rather a driver or kernel issue. Could you give some details on the hardware configuration you are using and the wifi device?

[Guilherme Bezerra dos Santos (gbsantos)]

My hardware configuration is
- Dell Inspiron 5547 A07,
- I7-4510U, 16GB RAM DDR3,
- QCA9565 / AR9565 Wireless Network Adapter Qualcomm Atheros
I used sudo lshw command for more details and attached here.

Please, see if it helps.

Tks!
