A few days ago lightening hit our house...Knocked out our modem (Spectrum)...Tech could see three bad ports and we replaced it the next day..Tech came out yesterday all is well with telephone, I'Net, TV...Cept my 2017 Imac Pro will no longer recognize an ethernet cable plugged in...(Have wifi) I know longer have Apple Care..My question is does anyone have any idea the cost of the card replacement off the top of their head...?? Thanks and Merry Christmas
 
Pretty sure that component is soldered/built directly into the motherboard these days making replacement prohibitively expensive if not out right impossible.

Yikkes...Perhaps I could try a USB Ethernet dongle thingy....

This would seem like the sort of thing homeowner’s insurance would cover, but yes, if your USB ports are working, you could get a USB-C to Ethernet adapter for not much money.
 
I was considering insurance, but the deductable is a grand..Although I dont know how much it would cost to repair, it couldnt be more than 300-400 bucks...(I hope), but it is Apple...
 
I wouldn’t hold my breath hoping for a $400 or even $500 fix. Without AppleCare or some other type of insurance I would expect any iMac repair that called for the computer to be opened up would be more money than a new iMac. Although saving an iMac Pro might be worth the expense.... but it won’t be cheap.

Not all that sure Apple Care would cover it anyway, certainly not a failure on Apples part...
 
Motherboard replacement on an iMac Pro is likely to be VERY expensive.

As suggested by others, use a USB/ethernet adapter/dongle.
Will get you connected again.
The cost for the dongle is little, and it will also "cost you" one USB port on the iMac.

But... them's the breaks.

I ordered it, should get here tomorrow...Im using an attached hub, or can connect direct...All around bummer....I may contact my homeowners Insurance tomorrow, just to see if its worth it, or even doable...Thanks All and Merry Christmas

Good question...never ran one from a hub.

It is worth asking Apple about the repair. As others have said, likley requires a new logic board, which is either $$ or $$$.

Depending on the damage, it may be possible that a third party board repair shop could fix it. Might be worth asking...

The dongle arrived and works fine..Very slight D/L speed difference, if any...


Download...as in internet? Good wifi is typically faster than your internet connection, at least for most folks.

Without know your service, and testing its throughput, hard to know where the bottleneck is. Your iMac has (had) a 10 GB NIC. Those are pricey. Assuming you could actually use 10 GB speeds...

The low-cost dongles are rated at 1GB as I recall, but for the price, I would not be surprised to see less than the highest rated speeds. Still, should beat average wifi, especially if you ever see any dropped packets or latency.
