SF315-41 How to solve my wifi problem?

ACER SWIFT AMD RYZEN 5
I switch on my laptop and the wifi gets connected automatically. But after a while the wifi gets disconnected and on clicking the wifi icon it does not show any network. On checkin the network adapter under device manager , the driver Qualcomm Atheros QCA61x4A Wireless Network Adapter has an error sign and on double clickin this driver it show ' The device cannot start (Code 10)'.

Now this is what I have already tried but has not worked for me
1. Network reset / Troubleshoot
2. Updating the aforementioned driver
3. Checking for drivers at the amd website (There are 2 wireless Lan driver so I am a liitle confused)
4. Uninstalled the driver and restarted my laptop

PLZ HELP !!!!!!

For the short term, using a WiFi dongle on a USB port is certainly a way to get back up and running. Error 43 is just a generic placeholder for "it didn't work" and could be the card still. If you are out of warranty take a look on a venue like Amazon for prices on M.2 WiFi/Bluetooth cards. They are all likely to have exactly the same antenna connectors, so they can be swapped in and out. My quick Amazon search says an Intel card that's the same function as yours (Intel Wireless-AC 9560) runs around $20, a WiFi 6 version (AX200) more like $25 and the latest version (AX210) more like $45. Compare that to the cost of a dongle and you might be best to just replace the card instead of going the dongle route.

There are a few things that can cause the WiFi to drop out, though the error message helps by removing some. Which specific model do you have? It should be something like SF3xx-xxx-xxxx. There have been a lot of Swift models over the years and pinning it down to one using the AMD chipset doesn't help a lot. Since you are using Device Manager I can likely assume you are running Windows, though some Linux dists also use an app called Device Manager.

What version of the driver is installed now?

The model no. is SF315-41
After facing the error I downloaded the driver from the acer page and installed it.Didn't fix the error.
Later , I updated the driver using Ccleaner .So I am using the latest version of

Qualcomm Atheros QCA61x4A Wireless Network Adapter

OK, so your Ryzen 5 is a 2500U chip. Does your model have 4GB or 8gB of memory? Does it have a HDD or SSD? It looks like the WLAN card is made bu Lite-On for Acer and uses an M.2 interface. Since you have updated the driver without it fixing the issue it's more likely the card than the drivers. Luckily those cards are pretty cheap. If you are in warranty contact Acer support to see what's involved in getting it fixed for you. If out of warranty now might be a great opportunity to upgrade from the 802.11ac card to a new 802.11ax to give you support for WiFi 6.

An update :

After uninstalling and reinstalling the drivers again , the driver is now showing a new error ( code 43).
Apart from the possible damaged wlan card is there a possibility that the problem is related to power options of the laptop

Also is using a usb wifi adapter a viable option
