ip link error and loading module sch_netem

[dkebler]

A comedy of distros
I can get armbian and dietpi to do the 'ip link set up'  to work but I can't get the hdmi to work
I can get the hdmi to work on the ayufan images but I keep getting the error

Code:

RTNETLINK answers :No such file or directory

when trying to bring up the wifi interface (not an issue on the other two distos.)

So seeing as I can't get the hdmi working on those two distos (and I must as I can't always ssh to complete my project) I need to get the ayufan image working with my usb wifi adapter.


So apparently I need to get this sch_netem module loaded.  It seems I can and the lsmod shows it is there but I can't get it to persist.

How does one go about persisting kernal modules (assuming the modprobe loads the module ok)??

In general the ayufan image is 'minimal' so I imagine I might have to enable more modules so basically my question is how to do this and in particular for the sch_netem module

ok I figured out how to get a module to load at boot
list it in etc/modules-load.d/modules 
then lsmod shows it is loaded.

sadly this does not eliminate the error.  I am still unable to bring the wifi interface up

The adaptor is supported and like I said no problems when bringing it up and using it in armbian and dietpi distros so this is NOT a hardware issue rather something is missing from the ayufan image/kernal

anybody got a working wifi adapter with ayufan image?
