I hope this is the right thread, please move if it isn't...

I'm investigating converting my NUC to a Pi 5 - the install from the official Pi5 image went perfectly but as I'm using a Mesa 7i96 and the Pi will end up inside the cabinet, I need to use a USB WiFi adapter for its external antenna.

The dongle is a Reaktek RTL8811AU (external antenna'd ones seem to be getting rare) so I think I need to install this: github.com/lwfinger/rtw88?tab=readme-ov-file#installation-guide Happy to be corrected if I don't because I'd rather not.

If I do aI get 6.12.11 but this:is "Unable to locate package linux-headers-6.12.11"

An apt search reveals a bunch of 6.1.0x Linux headers and a few 6.12.12+bpo headers but no 6.12.11. Not sure what to do now, so any guidance would be appreciated - even if it's a link to a natively supported USB WiFi!

Edit: Runninginstead of apt searching for 'linux-headers-6' reveals 'linux-headers-bcm2712-rpi/now 6.12.11-1 arm64' are already installed. Why the headers don't match the uname -a is slightly above my pay grade.

Hello,
I am installing ethercat but the communication light with the drivers is not flashing and it is not communicating with the drivers.
