Try to re-install drivers and packages for the wired/wireless device.
If you are using a wireless encrypted connection try to disable the security key, if that works you need to setup it manually if you want the security back.

Post the results of this command:
lshw -C network

@ titico
Thx for you reply. But it worked before (after a live CD install) and I just done a refresh install. Also I can ping. So therefore I dont think it is a driver issue.

BTW Its a wired connection, not wireless.

@ Codename

Thx I will give it a go when I get home and post the results.

To make it more strange *scratch that* bizar.....
As soon as I power up HTPC, the internet connection of my laptop fails
and no internet cables are connected to my HTPC!!!!

Its getting more strange by the minute

If my HTPC is off and I run ADSL speedtest I get 1456.9 KByte/sec. As soon as I power up my HTPC (no cables connected) I dont even get the internet page.

I am not kidding and I cant explain it!!

please help me out here

Kind regard

Are you using Mythbuntu? If not, what programs have you installed for you HTPC?

I would uninstall the programs one at a time and see if your internet connection works without x program.

You didn't install 8.10 Alpha 6, did you? If so, you might be a victim of the blacklisted e1000e Gigabit ethernet driver module. Check the first sticky here:

His/her LAN is a Realtek chip which uses the r8169 module. It is not affected by this.

Thanks you guys.

As I told in my previous post, I reinstalled Ubuntu and this didnt help. This made me think it wasnt an OS issue.

To verify this, I had to install a Win***s OS. With the new OS still no internet.

So my conclusion is: its an HW issue. A very strange HW issue, but still.

So if you guys dont have any bright ideas, I am going to RMA my motherboard :(
