For users who require a reliable wired connection without an integrated network card, the StarTech.com USB31000SA adapter converts a USB 3.2 Gen 1 port into a Gigabit RJ45 port in seconds. Based on the Realtek RTL8153 chipset, it supports 10/100/1000BaseT(X) in full duplex for maximum bandwidth over cable. VLAN tagging (IEEE 802.1Q) and support for jumbo frames up to 9,000 bytes make it a solid choice for structured network environments. Auto-MDIX eliminates the need for crossover cables, while three LEDs (activity, link, power) allow for immediate visual diagnostics. Compact—66 × 24.9 × 17 mm and weighing 36 g—it fits into any bag without being bulky.
