Boot up error

Failed to start Advanced IEEE 802.11 AP and IEEE802.1X/WPA/WPA2/EAP Authenticator

Reinstalling the package hostapd resolves this issue.

 

sorry if this is not the correct place to post this error.

It seems wifi is unstable and requires removing and readding the kernel modules brcmutil & brcmfmac when wifi stops responding.
