Thank you very much, @raschid ... that image is perfect, I can work with wlan0 and also with /dev/vide0!! However, an "apt dist-upgrade" destroyed the wlan0 after reboot. For being an octoprint controller only for the LAN, protected by a sophisticated firewall and only online when printing, I think that is a risk I can take (not to be upgradable). And the speed is also fine.
And of course, I have to cool it properly, the one chip heats up to over 65°C while idling, that's a bit hot, but I've seen other threads discussing that. Heatsinks and fans are on the way to my house.
I'm so glad, thank you again.
Is it planned for the near future to support WLAN with that kernel? What's the latest?
Time for some Orange Juice ... (is that what "Orangers" say to each other? ;-) )
