What is the problem?
I have raspberry pi b+ v1.2 2014 and it doesn't support wifi. I bought TP LINK wn821n(rtl8192eu) and can't set it up. I don't have ''wlan0'' connection
What did you already try to solve it?
I already tried to install the driver and most likely failed. I also read a lot of forums but did not give any result

There is barely enough information here for us to begin to provide help. If you had filled out the template instead of deleting it, we might be more helpful.
You are asking about a wireless adapter (https://linux-hardware.org/?id=usb:2357-0107) connected to a very old Raspberry Pi running an unknown version of OctoPi.
Since the core of OctoPi is based on the Raspberry Pi OS (Lite), you will probably get better help from either TP-Link forums or Raspberry Pi forums. Do a google search for " TP-Link TL-WN821N v5/v6 [RTL8192EU]".
If you wish to continue here, please fill out the template as completely as you can. The text(s) in blue are links to additional information which can help you figure out what is being asked for.

Excellent! You asked the same question in https://forums.raspberrypi.com/viewtopic.php?t=351230 and got the response, https://blog.junix.in/2017/07/11/tl-wn823n-driver-in-raspberry-pi-2-b/.
Follow the steps in that blog. While the blog is quite old, the last comment was from April 19,2023 that it is still valid. OctoPi 1.0.0 is based on Raspberry Pi OS Lite which is based on the Debian Bullseye release.
After reading through all the comments, I was able to build the driver on an RPi 4B with OctoPi 1.0.0 installed using the driver sources from https://github.com/clnhub/rtl8192eu-linux following the instructions in the blog and on that github page. This github appeared to be more up to date and had the advantage of including a script.
I think the memory (512MB?) on your Raspberry Pi Model B Plus Rev 1.2 may require an increase in the swap file size. You can google how to do that if necessary.
Of course, I don't have the hardware so I can't verify that the driver I built actually works.
Thank you very much for your reply
