Realtek does not list the RS1081B on its consumer front page, but the driver is included in the Realtek USB FE / GBE / PCIe Ethernet Controller Driver for Windows 11 package. Follow these steps:
If you want, provide the exact hardware ID string shown in Device Manager (the full PCI\ or USB\ ID) and your PC make/model; I can draft a tailored search and step‑by‑step installation for that specific device.

The previous drivers (versions 10.0.xxxxx) were written for Windows 10’s scheduler. With Windows 11, Microsoft introduced DirectStorage and improved thread scheduling for NVMe devices. The old drivers lacked the firmware logic to handle these features, leading to severe bottlenecks.
The new RS1081B driver (version 10.0.22000.101 or higher) was specifically re-engineered to address three critical areas: Realtek does not list the RS1081B on its
With the new driver, sequential read/write speeds on a Gen 3 NVMe SSD connected via RS1081B now consistently hit 1,050 MB/s (the limit of USB 3.2 Gen 2). More importantly, the new driver pipeline reduces CPU usage by up to 30% during large transfers, leaving more headroom for your games or creative software.
Even with a “new” driver, you may encounter problems. Here are fixes for the top 5 error codes. More importantly, the new driver pipeline reduces CPU
