Facing wifi related error with Swift SF314-55G.

I tried with multiple Intel wifi drivers (version - 20.50 / 20.70 / 21.70), windows update and windows reset but issue still exists.

Error is -
Intel(R) Wireless-AC 9560 : The version number is incorrect for this driver.
Intel(R) Wireless-AC 9560 : Has determined that the network adapter is not functioning properly.
Intel(R) Wireless-AC 9560 : Could not find a network adapter.
Source: Netwtw06

Can anyone help me to know what exact version of driver need to be installed?

    Re-enter Device Manager. Click on the network adapter folder. Uninstall the wifi adapter driver. Exit Device Manager without trying to install anything. Shutdown Windows. Turn machine back on and let Windows automatically re-detect and re-install the wifi driver. Jack E/NJ

    Thank you @JackE. I'm able to connect to WiFi network following steps mentioned by you.

    But error related to WiFi driver is still reported in Event Viewer (attached error log as text files).

    If DeviceManager now looks clean with no red or yellow warnings, just ignore the logs. I can't download them anyway to look at them. Do they have any date/time stamp? Jack E/NJ

    The error log seems to be a harmless remnant of earlier drivers that you tried to install? Were they generic Intel 9560 drivers or ACER-flavored Intel 9560 drivers? They are not the same. Jack E/NJ

    Earlier I tried both driver types (Acer Flavoured as well as Intel Generic).
    Acer Flavoured - Wireless LAN_Intel_20.70.0.5_W10x64
    Intel generic - WiFi_21.70.0_Driver64_Win10 (Earlier error due to this driver was similar but specific to netwtw08)

    OK. Next question. Why did you try either of those in the first place? Jack E/NJ

    One day while watching movie, system shutdown abruptly. On reboot I encountered WiFi connectivity dropping intermittently.
    Sudden change in system behaviour might be due to window updates.
    To fix WiFi dropping issue I proceeded with driver updates which didn't helped.

    >>>Sudden change in system behaviour might be due to window updates.>>>

    OK. This is common for Win10 updates. To help avoid this kind of thing in the future, make sure SystemProtection  is turned on in ControlPanel's 'restore point' app. That way, automatic restore points will be created by the update that you can use to reverse the update and block it until a subsequent update fixes the problem.

    Uninstall only! Don't try to re-install anything! Exit Device Manager without re-installing anything! Shut down Windows normally. Turn machine back on and let Windows automatically re-detect the hardware and automatically re-install a fresh copy of the correct driver.
