Applicable Environment This document standardizes the complete process of installing the official Realtek external NIC driver on pfSense 2.7.2 CE to replace the system built-in driver, ensuring normal recognition and stable operation of Realtek 8125BG network adapters. For Qotom mini PCs using the Realtek 8125BG 2.5GbE controller, you can follow the official Qotom installation guide […]
Important Recommendation: Use a USB 2.0 flash drive, and plug it into the USB2.0 port of the mini PC. USB3.0 may cause recognition or installation failures.
PCI Express (PCIe) is the mainstream high-speed serial interconnect used inside Qotom industrial mini PCs to connect M.2 NVMe SSDs, multi-Gigabit Ethernet adapters, expansion peripherals and computing processors. Each new PCIe generation doubles the signaling rate of the prior standard. The table below shows theoretical unidirectional effective bandwidth for each PCIe revision across common lane […]
