My laptop suddenly cannot connect to WiFi ("Can't connect to this network" error). I run the Acer Care Center, and it says that my system is up to date (including the drivers). I used Checkup to identify the problem, but "Troubleshooting couldn't identify the problem".
The wireless network card is Qualcomm Aheros QCA9377. I went to http://www.acer.com/ac/en/US/content/drivers and there are 3 Atheros drivers listed. I don't know if I should install a new driver and which to install since there are 3 to choose from.
Please advice. Thank you.
