Thanks @dosdude1 (and @BookEmDanno on a later similar post). I did find the cable disconnected. So i re-attached the cable, and upon powering off, both bluetooth and camera are now recognized and working. However, my WiFi is showing on the menubar with an "x" and drop down says "WiFi: No hardware installed".
System report does show software wifi 13.0.
Thanks for additional suggestions.
My WiFi is now LIVE! again on my mojave un-supported MBP5,5. Perhaps just got into a good karma. Didn't use this mac for a couple of days or so. Then all of a sudden ....
