Hi and thanks Noth and Reefshark, I have three interfaces, an Ethernet, embedded Atheros abg and a Proxim PCMCIA bg card. At this point I am manually loading the two wireless interfaced using t"ifconfig ath0 inet". when I do an ifconfig all three show inet6 and there is a sit0 6 to 4 tunnel interface that shows as well with the ip address of my Ethernet interface and a derived ipv6 address. I am having trouble getting the Ethernet side of my wireless cards working, the 802.11 side is fine and being a newbie to this linux stuff I think I did to much reading and jumped to a conclusion (probably incorrect and not a good thing to do anyway!) and since the interfaces come up fine and shows RX and TX traffic but many many errors I thought I the ipv6 was the problem. The Ethernet interface works OK!!!
