Hi, My Laptop Aspire E5-575G seems to have the internet connection especially when gaming.
the Qualcomm Atheros QCA9377 Wireless network adapter seems to malfunction showing that the device couldn't start (Code 10) after a shot while while playing an online games
I try both download and reinstall the driver from this page and reset the network, none of them seems to work. any suggestion?

Open device manager→expand network adapters→right click on Qualcomm wireless driver→select uninstall→check the box and select uninstall→ok
After uninstalling click on action→scan for hardware changes→restart your laptop

Already done it at the first time, only fix it at a time if I need it for work but not during playing online game

i guess there are some problems with this adapter. i have it on acer aspire a315. sometimes, after wake from stand by, after toggle aitplane mode, the adaper just dissapear from the laptop. windows does not see it at all. i even tried ubunti ant it did not work either.
the one thing that seems to work was to uninstall acer quick access application and not to use airplane mode anymore.
there was some times when i thought to buy an external usb wifi adapter.

Colleague @rich1974 suggested uninstalling acer quick access.

I keep getting a blue screen Windows Stop Code Error, DPC_Watchdog_Violation, every time the Qualcomm Atheros QCA9377 Wireless network adapter tries to connect to Wi-Fi. I have tried uninstalling it, I have tried updating it's drivers, I've tried turning off PC (Acer Aspire C27-963) bought this year and resetting the router access point, nothing works. It is frustrating, I can be working away on something, and bam blue screen!!! I would like to go back to using my TP-Link adapter, Qualcomm is a piece of cr*p!

Hey MassiveUwU thats NOT the latest Atheros QCA9377 WiFi driver, the latest is the v12.0.0.1016 so get it from the link I've provided as you will also need to update the Bluetooth drive to the latest v10.0.0.714. But first uninstall all the old drivers completely and then install these new drivers, This Qualcomm Atheros QCA9377 is a great WiFi/BT card but it needs to be setup properly, I’ve never ever had problems with older laptops as these Qualcomm cards are reliable and great performers, I also use this one and another excellent AR9462 in a V3-561G and they work 100% and are very speedy on 2.4 or 5G networks!

Re. my comment above about qualcomm atheros wi-fi adapter, it is fixed, it won't be bothering me again. Got a new adapter, downloaded drivers from new adapter manufacturers website, no more having to deal with qualcomm ever again
