I have a bad performing "longshot" (~10 meters):
both sides with recent LEDE, one 1043ND and one WDR4300 on 2.4GHz.

The link performs bad, although the values seem OK:

Both sides have set on 2.4GHz with channel 14:
wireless.radio0.chanbw=5
wireless.radio0.txpower=20

The question: what is "rx drop misc"?
I have a packetloss of ~20%. Any idea why that?
