Michael, Di you get my last post, where I said this: Oh no... There is a really long, documented problem with the natsemi dp83815 ethernet chip that Soekris used to use. They have since moved to the dp83816 which, along with a new driver, was supposed to fix these problems. The problem was with cable attenuation. I'm no EE, but the point is the net4801 was very finicky about the length of ethernet cables. Have you tried different lengths? 10ft? 100ft? See what happens. Anyways, two things: 1) The dp83816 is used on current net4801's, and it isn't supposed to have those problems. 2) The fix is already in the kernel (2.4/2.6) and has been for some time. -- Kristian Kielhofner _______________________________________________ Astlinux-users mailing list [email protected] http://lists.kriscompanies.com/mailman/listinfo/astlinux-users Donations to support AstLinux are graciously accepted via PayPal to [EMAIL PROTECTED] REMEMBER: AstLinux mailing lists are moving soon: http://sourceforge.net/mail/?group_id=170462 Please move any discussions ASAP!
