Best 2.5G Upgrade
UGREEN USB-C to Ethernet Adapter 2.5G
Our verdict: A 2.5Gb adapter on an RTL8156BG chip that still works on gigabit networks.
This UGREEN adapter delivers 2.5Gb Ethernet using an RTL8156BG chip, in an aluminum housing with status LEDs, priced $25 to $50. It is backward compatible with 1Gb networks, so it costs you nothing on an older router.
It ranks first because it is the only adapter here that goes beyond gigabit. If your router, switch or home internet plan supports 2.5G, the extra headroom is useful for file transfers and fast fibre plans. The aluminum housing helps spread heat, which matters for a chip that runs warm under load. It costs more than the 1Gbps models and offers no advantage if your network tops out at gigabit.
Buy it if you have a 2.5G port or plan to upgrade. Skip it if your whole network is gigabit and you want the cheapest option.
