Internet connection lost after installation

I installed Linux Mint 14 as dual boot with Windows 8. The system can not connect to the internet (no IP address). The strange thing is that Windows 8 can not also acquire IP address after the Linux installation (was working fine before) .
When i unplugged the ethernet the internet connection was fine on windows,but when i booted linux the connection was lost on both...

I am assuming you have tested with a wired, as well as with a wireless connection.

In Windows, click Start-->Run (or whatever you do in Win8 to get to a command window) and enter cmd in the "run" dialog (again, or whatever you do in Win8 etc.). When the command window opens, run "ipconfig /all" and copy and paste the output into a safe place.

Then in Linux open a terminal and run the command "ifconfig -a" and similarly save the output. You may have to do this with sudo.

Post the results of both commands here, making sure to enclose them in "code" tags, which become available when you click "Go Advanced" down there at the bottom of the Quick Reply window.

That will help start the troubleshooting.

You might post a little information on your hardware. Is this a new computer? or a computer you had on which you installed w8 and Mint?
I'm not a network expert but I can't see how installing an operating system on a separate partition would affect the software of another system on a different partition.

When i unplugged the ethernet the internet connection was fine on windows,but when i booted linux the connection was lost on both...
What? Does that mean the connection was good on w8 and you then unplugged the ethernet cable? What was the purpose of that? I think you'll need to post a little more detail to get help from LQ members with network expertise.

It's quite possible that drivers leave hardware / firmware in a certain state. I have this problem where a memory stick is occasionally not recognized on a Windows machine and even power cycling does not work. The only way to solve is is to reboot with the stick inserted; that resets something somewhere after which it is fine.

To the topic:
If you're connected to the web via a router, a possibly easy way is to assign a static IP address to your computer. In your case I would do so for both Windows and Mint.
Note that this, if it works, only treats the symptoms and does not take away the cause.

I don't think something like that should happen as I myself am using windows 8 and linux.

I think you should try to check IP in both OS

1. Run
2. CMD
3. ipconfig/all
check this as well
1. Run
2. ncpa.cpl
Please provide if you see you LAN

Linux Mint
1. Atl+f2
2. gnome-terminal
3. ifconfig/all
4. check your /etc/resolv.conf, /etc/network/interfaces

Its better if you provide with more detail or else I don't think we can help you enough.
