I have an HP T620 that I have freshly install Lubuntu 23.04 onto. I have found the device in “Additional Drivers” and downloaded the drivers successfully. I have rebooted a number of times but the wireless device never shows up. I have also tried the same steps with Ubuntu and I get the same problem, so I don't believe it's Lubuntu related.
I installed net-tools and ran ifconfig wlan0 and I get wlan0: error fetching interface information: Device not found. As far as I can tell the device is available, with a driver, but I’m missing a step here somewhere to get it to show up as a regular device and allow me to select a WiFi network.
I dug around as much as I can, and it seems like most of the existing issues with this device (BCM4253) are related to not being able to install the drivers properly, and AFAICT the drivers are installed and loaded properly.
