Raspberry Pi Dual-Band 5GHz/2.4GHZ USB WiFi Adapter with Antenna

If the on-board Wi-Fi antenna on your Raspberry Pi isn't giving you enough range, this dual-band 2.4GHz/5GHz USB 2.0 Wi-Fi adapter is a great option.

The antenna is dual-band meaning it can connect to a 2.4GHz or 5GHz network, and supports the 802.11ac standard (3 times faster than 802.11n networks).

Note: Currently only tested with the Raspberry Pi 3B+, Pi 4 and Pi 400 (we're working on finding a driver for older versions!)

The USB 2.0 adapter features an LED status light and removable antenna.

Installation

The adapter requires installation of a third-party driver which will take around 5 minutes. See installation guide here. - Raspberry Pi OS 32-bit Bullseye tested (Add arm_64bit=0 to config.txt)!
