Compact Wi-Fi 4 USB adapter for desktop

This Edimax EW-7811Un V1 adds wireless networking to any computer with a free USB port. It suits home or office PCs that lack built-in Wi-Fi or need a replacement for a failed internal card. The tiny form factor keeps adjacent ports free and works well on cramped motherboards or small-form-factor builds.

150 Mbps maximum link rate on the 2.4 GHz band

The adapter complies with IEEE 802.11 b/g/n and tops out at 150 Mbps over the 2.4 to 2.4835 GHz frequency range. That ceiling decides whether the device matches your internet plan or local file-transfer needs; faster AC or AX routers will not raise this limit.

WPS button and multi-OS driver support simplify

A software WPS push-button lets you join a secured network without typing a passphrase. Drivers are included for Windows, macOS and Linux, so the dongle works across the three major desktop platforms without hunting for separate downloads. Encryption options cover 64-bit and 128-bit WEP plus WPA and WPA2.

Questions about this item

What does the 150 Mbps rating mean for actual throughput on my PC?

The 150 Mbps figure is the maximum physical-layer rate defined by the 802.11n standard on the 2.4 GHz band; real-world throughput will be lower due to overhead, distance and interference.

Which USB interface does the EW-7811Un V1 use and what speed does it limit me to?

The adapter plugs into a standard USB port and its wireless side is capped at the N150 150 Mbps rate; the USB connection itself does not impose a lower bottleneck.

How much space does the nano dongle need beside the USB port?

The nano form factor protrudes only a few millimetres from the port, so it fits alongside neighbouring ports and clears most laptop cases without blocking adjacent sockets.
