I haven’t changed anything in home assistant for at least a few weeks. About 3 days ago, I noticed that HA wasn’t available when I tried to give google commands to turn on/off lights. Going to the HA instance locally also times out. Looking at the console, I see this over and over:
[44199.646168] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready
[44199.651399] brcmfmac: brcmf_cfg80211_set_power_mgmt: power save enabled
The only way to get HA back is to do a hard reset, but it only comes back for a few minutes before if goes back to this state.
Anyone know what might be causing this, and how to make it stop?
I ended up logging in at the console, and using nmcli to reconnect the wifi. It seems to be working, but I’m unsure as to why it was disconnecting and not reconnecting from the start.
I have the same problem. I can setup and run HassOS for days until I shut down, remove power and power it up. Then the wlan0 message you list occurs. Did you find a solution for this?
Logging into the console and reconnecting the wifi using the nmcli command fixed this issue for me. Never figured out why it was doing this to begin with.
