Wrong Network driver was only some internet

When I got only some internet I posted and now I know why. I know see that Suse 12.1 loads the wrong network card driver it loads Realtek 8111/8169 and I need Realtek 8111/8168 so as anyone can see this is why I get some internet but not all I hope I don’t have too remove anything. If someone would tell me how to install 8111/8168 cause I have it on a disk that I made for linux I just don’t know how to change or install it. Any help would be appreciated.
