RE: Please confirm Inspiron Integrated Network interface dead
Probably the adapter was fried thru the cable. Try a new cable. You might get lucky. Just use the wireless or you can add a separate adapter card. IMO since the computer and wireless work, use it instead of the hassle of changing to a new card. I find the wireless is better than the wired connection. Buy a UPS battery backup unit to protect the computer. Lightning could have fried the motherboard and other parts too.
