I was able to solve the problem. 1. 5.3.0-42 wifi worked 2. 5.3.0-46 wifi didn't work 3. booted into 5.3.0-42 with working wifi system 4. I used sudo lshw > lshw-42.txt to capture data 5. booted into 5.3.0-46 without working wifi 6. use sudo lshw > lshw-46.txt to capture data 7. I used diff command to compare the two .txt files 8. I determined that my hardware uses rtl8821ce driver but it wasn't working in 5.3.0-46 9. stopping and starting network-manager didn't work 10. I used cd rtl8821ce/ then sudo ./dkms-remove.sh to change directories and remove the driver 11. when I attempted to reinstall the rtl8821ce drivers in 5.3.0-46, I discovered that the kernel update hadn't installed the 5.3.0-46 headers which prevented the wifi drivers from working. 11a. I was able to connect using bluetooth and my samsung G8 phone as hotspot. 12. I have Synaptic Program Manager so I was able to see the kernel headers weren't installed with the kernel update to 5.3.0-46. 13. After installing the 5.3.0-46 headers, the "paused" rtl8821ce driver install continued and "magically" the wifi started working! 14. performed restart and cold boot to verify wifi works again!
