Raspberry Pi Dual-Band 5GHz / 2.4GHz USB Wi-Fi Adapter with Antenna
If the on-board Wi-Fi on your Raspberry Pi isn't giving you enough range, this dual-band 2.4GHz/5GHz USB 2.0 Wi-Fi adapter is a solid upgrade.
The antenna supports both 2.4GHz and 5GHz networks, along with the 802.11ac standard (up to 3× faster than 802.11n).

works find on Pi4B with bookworm
Was not getting enough range with built-in wifi so tried this. It adds at least 5 db to signal so it helps. Installed driver per instructions with no issues. Also turned off built-in wifi by editing /boot/firmware/config.txt to add a new line "dtoverlay=disable-wifi" at the end of the file. After one final reboot the new dongle was on wlan0 and everything worked as before.

Works well with R-PI
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.
