Conventions

Maximum wireless signal rates are the physical rates derived from IEEE Standard 802.11 specifications. Actual wireless data throughput and wireless coverage, and number of connected devices are not guaranteed and will vary as a result of network conditions, AP limitations, and environmental factors, including building materials, obstacles, volume and density of traffic, and AP location.

To ensure compatibility, you may need to update the adapter's drivers after an OS update. You can find the latest drivers at tp-link.com/en/download-center.

Use of MU-MIMO requires AP to also support MU-MIMO.
