I upgraded from 22.04 to 24.04 and my plug-in Wi-Fi tp-link device did not work.

What device do I have ?

The command

lsusb

gave me

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 17ef:4515 Lenovo Lenovo Portable HDD
Bus 001 Device 003: ID 2357:0109 TP-Link TL-WN823N v2/v3 [Realtek RTL8192EU]

but the command

sudo lshw -c network

did not show me any wireless definitions.

Fixing the problem

I followed the instructions in https://github.com/Mange/rtl8192eu-linux-driver.

The files you need may already be on your machine for earlier versions of Ubuntu, you may not need to download anything.

Because my server had no Wi-Fi connection, I used git to download the latest code to my laptop onto a USB device, and then used the USB device on the server machine. You may not need to do this.

I used the instructions to

• sudo dkms uninstall rtl8192eu/1.0 to uninstall the driver and
• sudo dkms remove rtl8192eu/1.0 –all to delete the drive
• reboot
• then followed the instructions.

Without the uninstall and remove the install did not activate the drivers.
