It makes no difference. Sometimes on reboot I get WiFi the next it doesn't and I still see on login in the following pop up over when it asks for my username on the tty.

iwlwifi0: Not associated and the session protection is over already...
iwlwifi0: linuxkpi_ieee80211_connection_loss: vif 0xfffffe01bdc0cf00 vap 0xfffffe01bdc0c010 state AUTH (synched 0, assoc 0 beacons 0 dtim_period 0)
But if I restart netif and routing in that order it comes up and stays up at least it did this morning up until now when I tried your suggestions and rebooted several times.
