Performance Analysis: Managing Expectations
It is important to review this adapter within the context of its design.
Speed: This is an 802.11n adapter on the 2.4GHz spectrum. You will not get blazing fast downloads comparable to an AC or AX router. You can expect real-world speeds of roughly 30 to 70 Mbps, depending on interference. For 4K streaming or massive file transfers, this might be a bottleneck. For HD streaming (1080p), web browsing, and Zoom calls? It is perfectly adequate.
Range: Because the "Nano" versions of this adapter lack external antennas, the range is modest. It thrives in apartments or homes where the router is in the next room. If you are trying to pick up a signal from a detached garage, you will likely need a high-gain adapter with external antennas.
