Help Requested interpreting Wireless Log, RT-AC66U, 3.0.0.4.260.21

[bheiser1]

On my RT-AC66U, running 3.0.0.4.260.21, I see the following under System Log -> Wireless Log:

SSID: "<redacted>"
RSSI: 0 dBm SNR: 0 dB noise: -90 dBm Channel: 44/80
BSSID: <redacted> Capability: ESS
Supported Rates: [ 6(b) 9 12(b) 18 24(b) 36 48 54 ]
VHT Capable:
Chanspec: 5GHz channel 42 80MHz (0xe22a)
Primary channel: 44
...

Under Wireless->General, I have the Control Channel set to 44. When I set that, the Channel bandwidth automatically set itself to 80 Mhz. I changed this from "Automatic" trying to debug an issue with a client being unable to connect (it didn't make a difference).

Anyway, since I have the Channel set to 44, I am trying to understand what the Wireless Log is telling me in this line:

Chanspec: 5GHz channel 42 80MHz (0xe22a)

Thanks in advance!
