How to Download & Install Ethernet Drivers for Windows 11/10
However, if you are looking for a specific driver for a device labeled "No 9700" (commonly a USB Video Capture Card or a Bluetooth Dongle) to work on Windows 11, here is the solution:
If you see “Windows cannot verify the digital signature for this driver” (Code 52) , you need to disable Driver Signature Enforcement. Here is the permanent fix for legacy hardware:
A: No. Microsoft Update Catalog does not host Gzcyc-specific OEM drivers. Windows Update will incorrectly install a generic USB Composite device driver that will not work.
This is the most reliable way to identify the true hardware ID.
The Solution: Copy that Vendor ID (VID) and Product ID (PID). Paste those numbers into Google followed by "driver." You will likely find that your "Gzcyc No 9700" is actually a Realtek RTL8811CU or a MediaTek MT7601U chipset. Download the driver for that specific chipset, and it will work for your Gzcyc device.

You won't find "Gzcyc.com" offering support. This is typical for generic electronics. The branding on the box or the device shell might be a random alphabet soup, and the hardware inside is actually a standard chipset disguised by a generic shell.
The Golden Rule: Don't search for the brand name ("Gzcyc"); search for the chipset.
Because "Gzcyc No 9700" is an unbranded, generic device, your long-term stability on Windows 11 may be poor. Generic drivers often lose connection after Windows updates or sleep/resume cycles.
Consider replacing the device with a certified Windows 11 adapter from a known brand (TP-Link, Asus, Netgear, or Intel) for reliable performance and automatic driver updates via Windows Update.
Always scan downloaded driver files with Windows Defender or Malwarebytes before installation.
