I relocated four hours from my previous town recently. While streaming yesterday, my computer was achieving about 22mbps with frequent frame drops in SLOBS. After conducting several speed tests, I realized my motherboard's built-in network card might be faulty. This came from running multiple tests on my tower using the same Cat 6 Ethernet cable, which delivered roughly 370mbps on average. Despite updating all motherboard and network card drivers, the problem persisted, leading me to suspect a defective network card. Regarding your question, a PCIe gigabit LAN card that replaces the onboard LAN could potentially resolve the issue if it provides a higher bandwidth connection.
