wlan0 is stuck on DOWN, NO-CARRIER

[acidvegas]

rfkill list shows phy0: Wireless LAN is not blocked.

But ip a is showing the interface as wlan0 and is DOWN.

lspci and dmesg shows nothing when grepping for network or wireless

sudo ip link set wlan0 up no response, link still down.

I am able to connect to wifi with wpa_supplicant which brings the interface up but we still see these errors looping in the syslog:

brcmfmac: mrcmf_set_channel: set chansepec 0x???? fail: reason -52

???? is random hex

You were able to get connected though with wpa_supplicant though, right ? I wonder if there’s some kinda power policy that forces it to remain down unless it’s actively associating or associated it’s kinda weird that you can’t manually set it to up but wpa_supplicant works if you run it while it’s down…
