I'm running High Sierra 10.13.6 on my iMac 18,2. The internet will only connect wifi not ethernet. I see "This computer does not appear to have any PCI Ethernet cards installed" under Hardware>Ethernet Cards. Will upgrading to Catalina solve this issue, or is there another option?
Thanks in advance

It is possible that a power surge (from lighting or some other source) has zapped the chip.
At this point you have three solutions.

Reset the SMC and NVRAM to see if those help.
Thanks for suggesting, but after reset I still have same the ethernet connection problem.
