I see something about "NetworkManager-wait-online..." failing to start
during boot up. It doesn't fail consistently, and I don't see any obvious
difference in system behavior either way.


After idling overnight dmesg reports a flood of
[76285.418728] brcmfmac: brcmf_set_channel: set chanspec 0xd022 fail, reason -52
[76285.526747] brcmfmac: brcmf_set_channel: set chanspec 0xd026 fail, reason -52
[76285.630745] brcmfmac: brcmf_set_channel: set chanspec 0xd02a fail, reason -52
[76285.734787] brcmfmac: brcmf_set_channel: set chanspec 0xd02e fail, reason -52
as if something's stuck in a loop. 

Wifi by way of the usb-wifi dongle is up, wavemon reports
freq: 2417 MHz [survey freq: 2462 MHz], channel: 2 (width: 20 MHz (no HT)) 
for the connected interface.

The internal interface reports 87% signal strength from the configured 
access point but the search has apparently stopped at 5825 MHz channel 
165 which can't work since it's a 2.4 GHz access point.

The network drop-down menu sees my access point through both interfaces 
but won't let me try to connect the internal without turning wifi off and 
back on (can't test further because I'm typing this over the wifi link). 

Thanks for reading!
