Details - LEDE is using wrong frequencies when country=de. In the official papers of the BNetzA[1] only these frequencies are allowed:

 - 5150 - 5250 
 - 5250 - 5350 
 - 5470 - 5725 

With channel=auto my device uses f.e. channel 149 which uses the fequency 5745. In that cases correct configured wireless clients can't find the AP anymore.

This is my setup:

 - Device: TP-Link WDR4300
 - Software: LEDE Reboot SNAPSHOT r3189-12db207   

Configuration for 5GHz radio:

        config wifi-device 'radio1'
        option type 'mac80211'
        option hwmode '11a'
        option path 'pci0000:00/0000:00:00.0'
        option country 'DE'
        option htmode 'HT40'
        option channel 'auto'
