[KLUG Hardware] PCI Eathernet card will not work

[Scott Cleveland]

Randall, I thank you for your suggestions.  I cannot believe what the 
solution wound up being.

I have 3 of these nic's, I stick to d-link because I have never had trouble 
before.  I switched my network cards out between my to Linux computers and 
sure enough the problem moved with the cards.


One thing of note:  I am running kernel 2.2.14 on both my Linux computers. I 
downloaded kernel 2.2.22 (I do not have all the right libraries to compile 
2.4) to my gateway.

When I boot the gateway with the good or bad network card in it, Kernel 
2.2.22 gives me the message "modprobe:modprobe can't locate module 
char-major-04"

Any ideas? I would like to run this newer kernel.

Thanks again
