Wireless Lan Adapter Issues

I have a 2 week old Aspire E5-575-33BM laptop. For the first week i had no issues and now sometimes when I power up the laptop there is not an internet/network connection. I have it connected to my 5G network and my Netgear 7000 AC router. The adapter is a Qualcomm Atheros QCA9377. Is the Atheros NFA 435 driver the correct one to use from the Acer support site for this model? Right now I'm using the Atheros 12.0.0.448 drivers dated 11/1/2017. Can anyone with this laptop and the QCA9377 adapter tell me what drivers they're using (assuming they have no 5G connectivity issues)? I've applied every Windows 10 update so I'm not even sure what driver was on the laptop initially when it worked correctly. I'm trying to rule out a driver/software issue before I try to replace the LAN card with something else such as an Intel AC 7260. I have to have a reliable connection, first time and every time.
