Please try resetting the NVRAM and restarting in Safe mode. If these still do not work the computer maybe damaged. You can take it to a Apple Authorized Service Provide to have it tested and then you can decide what to do.


NVRAM Reset & Safe Mode Reset instructions


One thing you can also try is getting a USB to Ethernet adapter to see if that will work. Something like:

Also, going forward please get yourself a VERY high quality surge protector that has insurance to protect your electonics.
