The amd machine I purchased has its ethernet socket on the motherboard along with its sound card function. Several versions of Linux I used on that machine could find the motherboard ethernet but none until ubuntu could get a dhcp address since dhclient and dhcpcd couldn't hndle that kind of ethernet connection. With ubuntu though using pump to bring up the internet connection 6.04 and 6.10 both were successful getting out onto the internet and ran firefox. The gnopernicus wouldn't work on 6.04 but does talk as a result of the upgrade to 6.10 that was done too. Installing standard ethernet cards into that AMD machine didn't get me any kind of internet connections either.
