Hello guys!

I recently had problems with my Ethernet internet connection. I got admission in University of Cyprus and I am staying in dorms. It is great here, but my only problem is that I couldn’t connect to the internet through Ethernet cable. I Called University Apartments Technics Team, and after they run some basic tests they come to conclusion that the port and the Ethernet cable was alright! So I took my computer to the Computer Store, because I thought that my PC was broken. They told me that my PC was totally functioning, my friend brought his Getaway laptop with windows 8 and he was connected fine. Fun thing is that every weekend when I go home, I connect my laptop to the internet through Ethernet cable and it is working just fine. And the same thing happened in the Computer Technical store. But for some unknown reason the internet wouldn’t connect in the Apartments! I reinstalled the drivers, I run ipconfing /all in the CMD and the Physical Address under Ethernet was 00-00-00-00-00. Then I run ipconfig /release and ipconfig/renew. Without any luck! I found in internet a program that is randomly changing the MAC Address of the computer but I had no luck there either.

But after some time I had an amazing idea! And I fixed the internet connection issue for ever. So I want to share this idea with you!

NOTE: I am not a professional computer engineer so I don’t know further stuff about this issue, and I don’t guarantee that this will work for you!! But it worked for me and I just want to share it with you!

Here it is what I have done:
1) Run CMD
a. You can click Windows key + R and type “CMD”
b. Or you can find it from the start menu by typing CMD
After CMD comes up, type “ipconfig /all” and hit ENTER

A list of internet connections and it’s details will pop up. Assuming that you have the problem, find the “Ethernet adapter Ethernet:” line and under it you should see “Physical Address. . . . . . . . . : 00-00-00-00-00-00”
That means that you don't have an internet access.

(I don't have 00-00-00... because i fixed already the internet issue)

But in your condition!
To fix that, what I did was:
I connected thought the Wifi to the University’s WiFi
RUN CMD again and type again ipconfig /all.
This time search the line that shows details about Wireless connection. My line is called: “Wireless LAN adapter Wireless Network Connection:” I think your supposed to be the same.

Under this line you should see “Physical Adderss:” and 24 digit number like 0F-45-A4-…..
Copy that number only!!!! (right click on the black section of CMD and choose “MARK”, highlight the number and then hit ENTER to copy)
Open a notepad and past it there
Delete the “-” between the numbers.

Now go to start. Type “Administrative Tools”, click on “Settings” under the search box if you are using Windows 8 and then click on the Administrative Tools to open it!

Open “Computer Management”

Open “System Tools”

Open “Device Manager”

Click on “Network Adapters”
Right click on your Ethernet driver name (Mine is “Realtek PCIe GBE Family Controller”)
9.PNG
And select “Propertise”
Click on “Advanced” tab
From the list find the “Network Address”
Under value click the dot near the box
IMPORTANT!!!
I don’t know what is written in this box, but for your safety copy the box’s content, past It In a new Notepad file and save it as “Network Mac Address Backup”. So if for some reason this will not help you, you will be able to restore the original settings.
NOW!! Final step
Go to the first notepad where we copied our Wifi’s MAC Address and deleted the “-”.
Copy that characters and past them into the box of your Ethernet’s Driver Properties!!
That’s it!!!
Hit “OK”

Close all unnecessary windows!
Now disconnect your Wi-Fi network and try to open Internet Explorer or Google Chrome!!
After that my internet connection was working just fine!!!

That was a great deal of work and you described the process very well, so I'm not gonna rain on your parade and correct your misunderstanding. No worries. Network engineering is clearly not your game (right now), but you would do well as either a software tester (under a good manager) or a technical writer of some kind. Keep up the good work!

I realise this is a very old thread and that you may not even be an active member anymore but just incase;

I wanted to sign up and say thank you! Took me and my dumb self literally days to try and sort this issue and not much was even coming up on Google.

This sorted it though although I have two WiFi adapters and the first Physical Address didn't work the second did, so thank you.

Dear max2010gold, as i mentioned above, i am not a professional on this topic. But i would suggest you to borrow a laptop from a friend, connect through WiFi to your home network and follow the above steps to configure the ethernet drivers on your PC with the data you will get from the laptop. I never tried this so i don't know if it is going to help you. (Notice: As some users mentioned you might need try all the available adapters when you run "ipconfig /all" in CMD ).

Good luck!

All i want to say is thank you! I've spend my entire weekend trying to fix this issue and got very frustrated. Nothing worked until i tried this. Now it works like a charm. I wish you the best with your computer skills!

DrikosRikos you are a life saver! I am a complete computer illiterate (for example: I was searching for 20 minutes how to reply to this thread) and I managed to fix my connection.

The steps were very clear and easy to follow. Good thing there were pictures though, otherwise I wouldn't have noticed that my DHCP was disabled. I googled it (I found the answer on In Microsoft Windows how do I enable or disable DHCP?) and it works like a charm.

Edit: Maybe just a problem on my end, but after shutting the computer off and turning it back on the next morning things went sideways. Now the computer can't detect the ethernet-cable anymore (which he could before the procedure).

Edit 2: Definitely a problem on my end, not due to procedure.
