Am using this board with the standard small wireless board (PCI?) and Im hoping to find how to talk to the registers and see if its running okay or not; a diagnostic kind of tool would be great

what happens is using the iw dev wlan0 set freq command, it refuses to set the frequency.  when using the luci webpage to change radio settings, click save & apply it crashes;  on reboot it says kernel panic, dumps the data and halts.

Im assuming its likely some software mismatch but dont know where to start testing

what debug tools do you experts use?
thanks
