Yes, when I say "setup screen" I really mean the Belkin setup page at 192.168.2.1. I can get this page with all versions of Knoppix when running wireless.
With a wired connection I can see the setup page and surf the net with version 3.8.2.
Version 5.0.1 connects when wired in that I can ping the setup page and internet sites but cannot view any pages with the browser including the setup page. Perhaps this is an IPv6 problem. If I remember correctly, version 5.0.1 did work when I used the network where I work which is a wired network. I will check this on Wednesday, as I mentioned in the previous post.
Version 5.1.1 does not connect with a wired connection which may be a driver problem with the network card in that I cannot even obtain an address from DHCP.
By the way I really appreciate your patience and effort that you are giving to help with this problem.
