10.13 High Sierra Wi-fi issue

Update process from 10.12 to 10.13 on mid-2011 iMac was uneventful. However, an issue is that after a shutdown/restart or waking from sleep, wi-fi won't automatically connect. Turning wifi off/on doesn't change anything. Wireless network SSIDs are hidden, so they don't usually (sometimes do) show up in the network list. After clicking "turn wifi on", when they show up in the network list, choosing one will make the connection. Steps I've taken:

Reboot wireless router
Remove existing wifi configuration files from /library/preferences/systemconfiguration, followed by reboot
Create new profile, reboot, still no automatic connection
Added a couple of DNS servers (8.8.8.8 and .4 for now). This didn't change anything
For the first time in forever, did an SMC reset, which didn't change anything

There were no wifi issues with Sierra 10.12, so this is new.

Open to any ideas. TIA!

same here, no issue with Sierra on my MBP Retina 15-inc (Mid 2015). Seems like only High Sierra my MBP is not connecting to the 5Ghz. Have no issue with connecting to the 2.4Ghz but not 5Ghz.

I would say there is a bug in the OS.
