the device was operate normally with super-channel
but now cant find any super-channel and find just the regular channels like 5180 5200 5220 etc
software version 5.7
is the problem from the routerboard or from the minipci ???

  1. make sure you enabled wireless mode “superchannel”
  2. manually write the desired frequency un “frequency”, do not expect a list.
