yes I buy a new computer and I have a lot of problems one of them is my network card (on motherboard) realtek 8111B.
Linux is Slackware 11 kernel 2.4 (try and with 2.6 the same thing) my network card was not found.
I downloaded r1000 driver from realtek site v5 and it doesn't work.
Here are some screen:

A lot of people do not know that 2.6.18 is a lot different than 2.6.9. Also the compiler version makes a big difference.

I recommend buy a PCI 100 Mb NIC. Eventually, PCI Express Realtek cards will work.

If I have to buy new hardware to use linux I will not use linux but that is not the point, I want to make this card work and becouse I can't do it alone, I come here for help.

PS
this is kernel 2.4.33.3

Send an email to Linus so he can recruit a network card developer that has a Realtek 8111/8168.

It is not Linux fault, it is motherboard manufactures that include hardware that is not Linux compatible. Also companies like Realtek need to follow through supporting their hardware in many OS.

BTW, I suggest using 2.6.x kernels because it has better scheduling and better for newer computers.

I solve the problem by installing kernel 2.6.19.2

I also had this exact problem,using Slackware 11.0 with built-in realtek 8111B lan card on my motherboard, then trying to compile the r1000 driver. Everything worked fine when I compiled and installed the 2.6.19.1 kernel. One thing happened after that though: I couldn't run my firewall until I also upgraded my version of iptables, but that wasn't too hard once I figured it out.

I will note this in my book.
