[wellylug] Only one of three ethernet cards works at a time

[Jeff Hunt]

Thanks for coming back to me on this Daniel.
Actually the problem is still there and very real. I put the best of
the hardware into another computer that correctly set up two cards but
continues to use only one at a time.

But I have just understood what you are saying. Why am I not testing
with distinct IPs? duuuh.
I'll try that.

How do I get a route table dump? A friend has suggested I should be
using wireshark but that seems a little extreme just to get the
computer to talk to the world.

Thanks
