Things to Consider

Full 2.5Gbps performance requires a 2.5G-capable router/switch, a USB 3.0 port, and a CAT5e or better cable. Missing any one of these will cap your speed. Older operating systems (pre-Windows 10, older macOS, Linux) may require manual driver installation to reach 2.5Gbps. Check your OS version before buying. This adapter is not compatible with Nintendo Switch or Smart TVs. If you need wired connectivity for those devices, look for a different product. Competitors include Anker and UGREEN USB-C hubs with Ethernet, or the ASUS USB-C2500. Compare features and price to find the best fit. ## FAQ
