Hi,
I have two Zyxel NBG6716 devices running CC r43392- one as AP and one as
STA (with STA firmware) and try to connect them via IEEE 802.11ac (wlan0).
Now I observe the following (reproducible) behaviour: in case I connect to
the CC AP, my client says:
{{{

However, an AP running the original Zyxel firmware results for the client
in:
