Is there someone here that has sucessfully replaced the Realtek network chip and know that it should work without any other adjustments or settings, well then I know that I have done something wrong when I replaced the chip.

Thank you for your reply!
I will probably go there tomorrow now that I have something to try.

Hi,
My name is Krister Koppari and I live in Sweden.
I love to fix broken things, especially electronic things.
Me and my family lives in a village called Mullsjö about 40km south of Umeå.

Cheers and have a nice...
