Ethernet cable unplugged

Question

I turned off my Mac while a severe storm. Turned it back on after the storm, it does not connect to internet.

I tried with my PC laptop, it connects all right so it is not a problem with the modem nor cable.

I turned off Mac and modem, unplugged the cable and back Mac on after the modem started, etc.

My Mac is iMac 21.5 inch, Late 2009; OS X El Capitan 10.11.6; ISP is Comcast.

Latest Incompatible Kernel Extension Configuration Data is 3.30.1

I hope someone has a solution, hopefully not too technical.

Thank you.

iMac (21.5-inch Late 2009), OS X Yosemite (10.10.4)

Open up Network Utility and check what happens when you plugin the cable into your computer.

Holding the button option and clicking on the wifi icon will bring up more options, have you tried running the diagnostic?

Diagnostic says this computer does not seem to be connected to a DSL or cable modem, or to an Ethernet network.

Network Utility shows (in Info tab) nothing but the hardware address and Link Status is Inactive.

I have never used Network Utility, what else I can do?

Actually, after chatting with the Apple Support, I figured that the port may be damaged and visit Apple store.

SMC and PRAM reset did not work.

Thank you for your help.
