Even with driver version 21, users report issues. Here are solutions:

As of 2026, Realtek has not released an official version 22 for the RTL8153 chipset, as the chip is considered mature. However, some JP1081B clones use a newer RTL8156 (2.5 Gbps) chip, which requires separate drivers. Version 21 remains the latest stable release for 1 Gbps variants. For those seeking 2.5 Gbps performance, look for JP1081B v2 hardware – but that is a different product line.
