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.
The adapter requires installation of a third-party driver which will take around 5 minutes. See installation guide here. - Raspberry Pi OS 32-bit Buster or Bullseye tested!

I didn't think of looking here for installation instructions (I forgot where I ordered it) and ended up installing pre-compiled drivers using a script found here, http://downloads.fars-robotics.net/wifi-drivers/install-wifi, and following instructions found here, https://raspberrypi.stackexchange.com/a/75108/19002 and https://www.raspberrypi.org/forums/viewtopic.php?t=194859 . The installation script automatically found the Realtek vendor:device ID of 0bda:c811, and installed a 8821cu driver for the appropriate version of Raspian.
