The problem was Windows 10.
Device Manager refreshed. The yellow exclamation mark vanished. Under “Network Adapters,” a new entry appeared: . vk-qf9700 driver windows 10
Arjun held his breath. He plugged an Ethernet cable from the dongle to his switch. Windows 10 assigned an IP. He pinged Google. Reply from 8.8.8.8: time=14ms. The problem was Windows 10
But that night, when he went back to the forum to thank Necrosoft, the page was gone. Not a 404 error—the entire domain had expired. The last cached snapshot showed only one final post from Necrosoft, timestamped 11:47 PM the same day Arjun ran the script: The dongle wakes. Now it knows your network. Be kind to it. Arjun unplugged the VK-QF9700 from his laptop. For a split second, before the LED died, he could have sworn it blinked twice—faster than any normal light. Under “Network Adapters,” a new entry appeared:
The original poster, a user named , had written: Windows 10 build 1511 killed the signed driver. But the chipset (AX88772) has a backdoor. The driver isn’t the problem.

The green LED on the dongle blinked once, then twice. Then it glowed steady.
He’d spent two hours on generic driver sites that looked like they were designed by pop-up ads from 2004. He’d downloaded “Driver_Booster_2024_Final_Edition.exe” and immediately run three antivirus scans. He’d even tried the old trick of manually pointing Windows to the folder where a Linux driver lived, just hoping for a miracle.
