Public bug reported: Problem is actually with cfg80211 and CRDA:
Dmesg output: [ 108.370194] cfg80211: Loading compiled-in X.509 certificates for regulatory database [ 108.381953] cfg80211: Loaded X.509 cert 'sforshee: 00b28ddf47aef9cea7' [ 108.416481] platform regulatory.0: Direct firmware load for regulatory.db failed with error -2 [ 108.416488] cfg80211: failed to load regulatory.db [ 108.643561] Broadcom 43xx driver loaded [ Features: NL ] I have spent a day putzing about with this, it was working on Xeniel, now Bionic has broken it. I am trying to save an old lenovo laptop from the scrap heap. Maybe it belongs there. I only have ethernet in the basement. It is cold down here.
