Unhandled exception when trying to connect to WEP network on Asus-F5R notebook

ReactOS 0.4.14-dev-844-gea35843 tested on Asus-F5R notebook PC.

Notebook characteristics: https://www.comx-computers.co.za/laptop-specification-sheet.php?laptop=17223.

Wireless network adapter is Atheros AR5006EG. The following driver has been used from the official Asus website: https://dlcdnets.asus.com/pub/ASUS/nb/F7E/WLAN_Azurewave_GE-780_XP.zip.
It installs successfully, and after reboot, networking works ("wlanconf -s" shows all available WEP networks). But when trying to connect to my WEP WiFi network, after typing "wlanconf -c SSID -w xxxxxxxxxxxxx", nothing appears in the command prompt, but in the log I see the following unandled exception in ndisuio driver:

(drivers/network/ndisuio/ioctl.c:203) Final request status: 0x0 (10)

(drivers/network/ndisuio/createclose.c:56) Removing binding to adapter \Device\{9402ee4b-fc79-40e3-b578-dcdcf423635f}

And still no networking.
Also in Device Manager, it the adapter properties, "Radio" is always "Off" and it fails to change after setting it to "On" and closing the device properties, although in registry it already is 1 ("On"). It is enabled on the notebook too (LED indicator is active).

Full debug.log is also attached.

UPD: When I creating this ticket, there also happened mystical Winlogon crash, which caused fatal system error, after closing the crash messagebox. But I hope that it is unrelated to the main problem.
