Overview
A tiny radio and a fast USB plug are all there is to this dongle, which stays nearly flush with the port. The pre-loaded installation means the driver arrives with the adapter, and the quick installation guide is the only extra in the box.
The reason to buy is a nano-sized adapter that brings current wireless standards to a machine with older wireless. The limit is a narrow operating system list and no external antenna to extend reach.
Who it's for
Travelers and desktop owners who want a small plug-in upgrade will find the size convenient. Those who need long range through several walls, or who run Linux or macOS, should look at a larger adapter.
Pros and cons
- Nano size travels easily
- Dual band operation
- Modern security standard listed
- Windows releases only
- No external antenna
- Needs a fast USB port
Performance notes
Real speeds depend on the router, the band in use and the distance, because the listed rate is a ceiling. MU-MIMO helps when several devices share a router, and OFDMA reduces waiting between devices. A fast USB port prevents the computer link from limiting throughput.
