What to know before buying

The advertised 1800 Megabits Per Second is a combined headline. The listing separately claims up to 1201Mbps on 5GHz or 574Mbps on 2.4GHz, and actual throughput depends on the network and conditions.

Listing details to confirm

Windows 7 is given as the minimum OS version in details, while feature text specifies only Windows 7/10/11. Tablet compatibility is listed without an operating-system or setup clarification, so confirm support for the intended device before buying. The claimed speed figures and driver arrangement are not independently verified.
