• OS X/macOS 10.4 – 10.14 (For 10.12+ through 10.14, use the latest drivers)
• macOS 10.15 Catalina is not supported as Realtek has not updated drivers and software for new requirements from Apple for DriverKit and 64-bit operation.
The small size of this adapter makes it extremely portable and keeps it nicely flush with the USB port. However, the small antenna has trade-offs in terms of range and performance.
We recommend using with an access point or peer wifi adapter that is in the same room or nearby. The adapter works best with line of sight to the access point.
A laptop with built-in Wi-Fi antennas can cause interference and connection problems. We recommend to disable the internal Wi-Fi or to use a powered USB hub or cable to help get the nano adapter out of range of other signals.
Peer-to-Peer (Ad-Hoc) connections
Because of its small size, the adapter is especially useful for setting up a separate, peer-to-peer (ad hoc) connection between two wifi adapters. Search “ad hoc wifi setup” for details.
Download and install the latest drivers
We recommend installing the very latest drivers, available at
For Windows 7, 8, and 10, if you have another active network connection, simply plug in the adapter and Windows will automatically download and install the latest drivers from Windows Update.
Once the driver is installed, use your operating system’s standard built-in support for making a new wireless connection to an access point.
Q: The documentation from Realtek for the RTL8188EUS chipset indicates that the adapter is capable of 150mbps, and your Amazon listing indicates 150mbps, but I’m getting way less than that. Why is that?
A: Without getting into too many details, the 150mbps value represents the maximum “Link Rate” of the adapter, which essentially tells you what wireless specifications are being used for the adapter. Environmental factors such as surrounding radio interference, distance from your access point, and other issues will reduce the performance and possibly the link rate being achieved. 150mbps (18.75MB/s) is the theoretical maximum transmission speed that can be achieved providing all conditions are ideal, such as in a radio testing facility. For home and office use, there will always be factors that reduce performance.
If you are consistently seeing a link rate of 72mbps reported by your operating system, this is either due to a configuration error on the router you are connecting to, or because of limitations on the router. If the router’s 2.4GHz channels are set to use 20MHz widths, the link rate will never exceed 72mbps. To get the 150mbps link rate, the router must be using channels with 40MHz widths.
