Ethernet card stopped working in my Macbook Pro

I would not attempt that myself, knowing how Apple puts things together. See if there is a youtube video with step by step instructions, but still...It might be worth having a qualified tech do it. I'm assuming you already power cycled it and made sure your wifi is functional to other devices.

Yep, posting from my PC now, which I use the same router.

It’s built into the motherboard and cannot be replaced. Computer makers have been doing that for almost 20 years. Try resetting the PRAM and SMC: https://thenextweb.com/lifehacks/20...reset-the-pram-smc-on-your-mac/#.tnw_we24vbZp
Apple laptops are so prone to needing new motherboards that Apple charges a premium for extended warranties on them. It’s not so common now, but five years ago I remember hearing another story about a dead Macbook Pro every week. They’re like the nuts on Gibson guitars.

Have you tried calling the Ether Bunny?

I hear his charges are up the ass.
But if Wi-Fi AND Ethernet are both not working, it might not be hardware.
They're two different chips.
Have you tried any other apps besides the browser?
Any diagnostics you can run? I have a couple MACs here, but I honestly find them impossible to work on in terms of troubleshooting problems..

Yeah, everything else seems to be working on it. Router is working fine, since I'm posting this thru it on my PC.
No, I mean on the MacBook.
It can't JUST be the Ethernet card if Wi-Fi is also kaput. They are two different things. Physically.
What are the symptoms?
Is it just that you can't browse using Safari or Chrome or whatever browser you use?
That could be a problem with the browser.
Can you open up a terminal window and ping your gateway?

I use Safari on it. When I click the Safari icon when it's working, the icon will 'bounce' for a second or two as it's opening up. It's not 'bouncing' at all when I click on it. And yes, everything else seems to run just fine on the MacBook. I can open up anything else on it that I've tried.
Do any of those other things want to connect to the Internet? If so, do they still work okay?
And just to eliminate any confusion, don't use any of the software update or App Store tools to test. I believe they use Safari under the covers.

I had a first generation Intel Macbook that I retired last year never needed a new motherboard. The MacBook pro my youngest daughter is using is 4 years old, with no issues and my oldest's MacBook is going on 5 years. When I did support at a university where several Doctor's used Macbooks, there were no motherboard issues that I remember other than the doctor who dropped is Macbook and shattered the screen and cracked the board. Apple care for a Macbook is a little more than an iMac, but that seems like it would be the same for any brand. Laptops are bound to take more hits than a desktop.
Anyway, what I'm really getting at is that I wouldn't suspect a hardware issue when BOTH WiFi and Ethernet are not working.
It might even be a duplicate IP address on your network. Usually, rebooting your router clears that up.
It might be a settings thing or a software thing.

So that doesn't sound like your Ethernet or wireless has issues.
Got to system->Network. Hit advanced and click the TCP/IP tab and check to see that you have a valid IP address, something like 192.1681.2.x. or 10.1.1.2. Make note of the Default Gateway address. Open the Network Utility and goto Ping. in the address bar, type your Default Gateway and hit Ping, see if you get a reply. It will either time out or give you a response. If it gives you a response, your hardware is fine. If it times out, try resetting the PRAM, that fixes all kinds of issues.

looks like I have a valid IP address, but no idea where you are finding 'Default Gateway address', nor where to go to get a ping. I don't see what you are talking about

I forgot, Apple calls it "Router"
Use Finder to search for Network Utility (it is in System->Library->Core Services->Applications)
