Problems with RealTek Ethernet Card on Fedora 9

[Bushido89]

Hi everyone,
My friend recently damaged his PC (was running WinXP) and asked me to help fix it, since we're students awaiting a student loan payment, we don't really have the money to go and buy a fresh copy of XP, so I decided to give Linux a go, and think I may have wandered into the deep end. The following Distros have been tried on two PCs, with the same results:
Ubuntu 8.10
Ubuntu 7.10
Fedora Core 9;
What is odd, is that (when running from the LiveCD) my computer, as soon as an ethernet cable is plugged in the back, immediately communicates with the router (connected directly to the cable modem, Virgin MediaUK) and is internet ready in seconds, whereas my friend's computer does not, yet, the Ethernet Card clearly seems to recognise a connection, as I see flashing lights coming from both the modem, and the ethernet jack. So, after a while of swapping peripherals from one machine to another, and trying every script/tutorial I could to insert the r8168.ko driver into the kernel (though I am still unclear as to what exactly the kernel is...though it seems pretty core.) I moved to Fedora 9, which boasts exceptional hardware support in it's latest Distro, but yet...it too cannot seem to play-ball with the Ethernet Card.

I apologise if this is a very stupid question, or if I have missed something blindingly obvious,

Thanks in advance

hi

As i understand, your problem is

1. Internet is not working on computer
2. your setup is

Internet-->Modem---->router---->>>Internal Network

then please make sure you have only one service is running , NOT BOTH OF THEM
1 network
2. network manager

if both are running stop the NetworkManger

hopefully it helps

Thank you I will try it now and pray for the best *consults google as to how to stop services*

Thank you for the advice, though I tried it, and there's still no change . Makes sense I suppose since it works fine 'out of the box' on the other computer...I am pretty confuzzled
