Hello everyone,
CONTEXT:
- I have an iMac running OS X Yosemite 10.10.2.
- I am looking to get an internet connection via an Ethernet cable. To do this, I have an RJ45 wall socket in the room where my computer is located.
- This socket and my Ethernet cable are working perfectly as I tested them on a laptop and the connection is fine.
- Regarding my router, I have an internet service provider (COMCABLE) that works the same way as Numericable; that is, by providing me with an internet connection through the TV antenna.
- There are no issues with this modem. Internet access works very well via Wi-Fi (including the iMac) as well as via Ethernet cable (except on the iMac).
PROBLEM:
- When I connect the Ethernet cable to the iMac, and open the network preferences, I notice an "orange dot" next to the Ethernet connection mode, with the following description: Auto-assigned IP address.
Then on the right side of that same window, the following message appears:
"Status: Connected
Ethernet has an auto-assigned IP address and will not be able to access the Internet."
- The configuration is set to "automatic". I have tried using the manual configuration assistant; but without success as I do not know all the required parameters.
So, my question is as follows:
- Has anyone encountered this problem before?
- Could someone help me configure the internet connection via Ethernet step by step?
- If I need to find information about the router (DNS server, search domain, router number, subnet...) to configure it, where and how can I find it?
Thank you in advance for your responses,
Best regards,
Olivier.

Hello everyone,
Thank you for your responses, my problem is resolved!
Indeed, after several tests in the house on all the different RJ45 wall sockets (I have 5 spread throughout the living room and bedrooms), it turns out that only the one I want to use is not working.
As soon as I plug the Mac into any other socket, the ethernet connection executes perfectly and automatically.
So, the problem does not come from the wall socket itself, but from the splitter (the term may be incorrect) corresponding to this RJ45 in my electrical cabinet. I just need to change it!!! ;)
However, one question remains:
How does this damn laptop running Windows manage to establish an ethernet connection with a faulty splitter??? lol...
