Hi there,
I've recently purchased a new USB Wi-Fi adapter: Alfa AWUS1900.
It's brand new and bought it specifically 'cause since it was first released to the public in 2013, it has drivers from Windows XP up to Windows 10.
As a matter of fact, I quickly downloaded the drivers from here (official Alfa website): https://files.alfa.com.tw/?dir=[1] WiFi USB adapter/AWUS1900/Windows
On Windows 10, when I ran the Setup Wizard, everything was fine and the USB adapter was working, but when I tried to install the drivers on Windows XP using the same Setup Wizard, it prompted me to a big fat bluescreen.
I tried to reboot and do it again: bluescreen.
I tried to install the driver in safe mode: bluescreen.
I rebooted, I logged back in my account and I installed the driver by prompting the installer to the location of the .ini file on my desktop \windows_xp_32_64bit_1024.6\windows_xp_32_64bit_1024.6\RTWLANU_Driver\WinXP and the installation completed successfully, however the Device Manager says "This device cannot start. (Code 10)".
What really p***es me off is that they even advertise "Compatible with Windows XP" on the package but it clearly doesn't work! (I can post a picture if you want).
I would really like to know whether it's them not testing drivers on XP or me who has something wrong in my configuration.
This is what Microsoft website says about error code 10:
QuoteCode 10 "This device cannot start. (Code 10)"
Full Error Message
"This device cannot start. Try upgrading the device drivers for this device. (Code 10)"
Cause
Typically, the device's hardware key contains a "FailReasonString" value, and the value string is displays an error message defined by the hardware manufacturer. If the hardware key does not contain a “FailReasonString” value the message above is displayed.
Recommended resolutions
Update the driver
Useless of course, as I can't update the driver, I already have the very latest and greatest version! -.-
