I upgraded my Mac OS To OS X El Capitan.
Now it is not getting connected to internet via Ethernet cable but Wireless works just fine. What happens is when I connect the Ethernet cable it says self assigned IP as shown in screenshot.

I have tried to manually enter all IPv4 information but doesn't help
Nov 22, 2016 How to network two MacBook Pros together via Thunderbolt 3 Video. The Mac you wish to connect to, and you should see a Thunderbolt Bridge with a Self-Assigned IP. Physically connect the two Macs via a Thunderbolt cable. On Mac 1: - System Preferences-Network - You should see Thunderbolt Bridge on the list of interfaces, with Self-Assigned IP and an amber/yellow status - Change the Configure IPv4: field from DHCP with manual address to Manually - Change IP Address: e.g. I use 169.254.1.1.

This article will talks about the
Self-Assigned IP
issue and will hopefully fix your problem. Here is the relevant part:To reset the firewall, go to the /Macintosh HD/Library/Preferences/ folder and remove the file called 'com.apple.alf.plist,' and then restart your computer. After the system boots, you may be prompted to allow incoming connections to numerous programs and services, so accept these for now (you can always go to the Firewall settings and deny or remove entries later on) and then try connecting to the network again. While configuration changes from migrating or restoring a system can lead to this problem, at other times major system crashes or power outages can do the same.

I was having the same issue and couldn't resolve until I followed this advice:
Many cable modems bridge only the first MAC address they see. If you unplug your router and plug in your Mac, you may need to reboot your cable modem so it accepts the Mac's MAC address. You'll need to reboot it again if you switch back to your router.

In my situation, I had unplugged the ethernet cable from my wifi router and plugged it into my Mac. My cable modem presumably didn't bridge the new MAC address, leading to the network problem. Rebooting the cable modem resolved the issue.

It sounds like perhaps the wire and/or setup of DHCP (assignment of IPs) might be an issue.
Here are some items to try in order:
- I would verify that the cable is making a good connection on both sides. Disconnect and reconnect both ends.
- Try a different patch cord.
- Check your network settings: System Preferences, Network, Click on the Ethernet on the left. On the right, it should say 'IPv4: Using DHCP' on the drop down.
- If that was already set, try the 'Advanced' button, then 'Renew DHCP Lease'
- Finally, some people have reported success by removing their 'Ethernet' config from the Network settings and then re-adding. To do this:
- Click on the Ethernet entry on the left in Network Settings
- Click on the minus sign under the list (this removes it)
- Click on the plus sign under the list. Select 'Ethernet' on the Interface Dropdown (this will add Ethernet back)
- Finally, click APPLY for the new interface settings to be saved. After a few seconds, you should see 'connected' and clicking on the interface will show you your IP address.
If these don't work, you might have a legitimate hardware issue. I would recommend a call to Apple (they will help you over the phone generally, depending on how old your Mac is and whether or not you have Apple Care.) Alternatives: a visit to your local Mac shop (there aren't many, but there are some) or a visit to your local Apple Store.

I think all Mac users can agree: Thunderbolt is both fast and flexible. Not only is it capable of 10 Gbps of bi-directional throughput on each of the dual channels in its original form and 20 Gbps max on a combined channel in Thunderbolt 2, it can also transport PCIe, USB 3.0, FireWire, Mini DisplayPort and gigabit ethernet data. But that’s not all: you can also daisy-chain up to six Thunderbolt devices per Thunderbolt port on your Mac. With six available Thunderbolt 2 ports on the new Mac Pro, that adds up to a plethora of possible peripherals.
With Mavericks, Apple added one more trick up its Thunderbolt sleeve: the ability to create a 10 Gbps connection between Macs using IP over Thunderbolt. As Intel just announced that it plans on bringing this functionality to Windows users for the first time, it seems as good a time as any to see just how this Thunderbolt networking works.
How to set up Thunderbolt direct connection
The setup on the Mac is relatively simple.
1. File sharing
Set up file sharing in System Preferences > Sharing. You should also record the user names and passwords for each system.
2. Connect the two Macs
Attach a Thunderbolt cable between two Macs. Open System Preferences > Network and choose Thunderbolt Bridge in the network interface list on the left hand side of the window. Grab the IP address.
If you click on the Advanced button, you'll find a set of tab for more options. Under the Bridge Status tabm you can see if your Thunderbolt connection is active.
3. Connect to Server
Go to the Finder and press Command-K (or select Go > Connect to Server). Enter the IP address in the Server Address field and click Connect.
A message will pop up asking you to type in the user name and password for the shared system. Enter that info and pick the volume you want to mount and click OK. If you want to see that mounted volume on the Desktop, go to Finder > Preferences and check the Connected Servers box in the General menu.
Benchmarks
When we tested two new Mac Pros over a gigabit network connection with a standard ethernet cable, we saw read and write speeds of a 10GB file of just below 100 MBps. When we copied a set of smaller files and folders, we saw read speeds of 78 MBps and write speeds of 64 MBps.
We saw an increase in file transfer speed when we disconnected the ethernet connection and used IP over Thunderbolt. Transfer speeds for our 10GB file jumped to a more impressive 241 MBps (write) and 390 MBps (read). The results in the files and folder test didn’t fare as well, with write speeds of just 133 MBps and read speeds of 243 MBps, but these results were still faster than when connected via gigabit ethernet.
Next, we connected a LaCie Little Big Disk Thunderbolt with two 512GB SSDs in a striped array to one of the Mac Pros and enabled file sharing on a volume on that drive. Still connected via IP over Thunderbolt, we mounted the shared LaCie volume on the other Mac Pro and ran the tests again. The results weren’t as fast as when we tested using a folder residing on the Mac Pros, but the differences weren’t huge. The 10GB file write was about 6 percent slower on the external drive share, while reads were about 12 percent slower. Reading files and folders was a little more than 10 percent slower on the external share and writing files and folders was about 25 percent slower than testing a shared folder residing on one of the Mac Pros.
Of course, you can always copy files from one Thunderbolt-equipped Mac to another using Target Disk Mode. When we ran our tests under that setup, all results were faster than the IP over Thunderbolt transfer speeds. The 10GB file reads and writes were about 7 percent faster; the files and folders read test results were 21 percent faster, while the write test results wear 83 percent faster. The downside of this configuration is that you have to boot one of the computers into Target Disk Mode, making it essentially an external drive and unusable as a computer.
Our final test was connecting the LaCie to the test Mac Pro directly over Thunderbolt and running the benchmarks again. This configuration was, by far, the fastest we tested. The 10GB file write speeds were nearly double those of the closest configuration, the Thunderbolt Target Disk Mode, and the read speeds were 55 percent faster than Target Disk Mode. The files and folders results were 59 percent faster (write) and 77 percent faster (read).

Thunderbolt networks may not be as fast using a directly-attached Thunderbolt drive, but when sharing files you need to take into account that you have to write out the data to a drive, disconnect the drive, connect the drive to another Mac and copy the files off of the drive and onto the computer. It's certainly faster than using gigabit ethernet.
