Lets try to trouble shoot the problem systematically.
First, try each card separately on your internal network, with the other
card not installed. Then, if each card works by itself, then place both
cards in the system, and test with one card on the internal network and the
other card idle (you might want to use a terminator). This test will see if
there is a problem with two cards.

Another issue that may affect you is plug and pray. Try turning P&P off (if
your system allows that). In any case, once you have guaranteed that both
cards work of that you have discovered the flaky card, then test the good
card with mediaone with the second card out of the system. I don't remember
what cards you have, but I found that some of the LinkSys ISA cards don't
work on all the IRQs that the docs say they can. Also, I seem to remember
that one of your cards is a Tulip card. There was a bug in the Tulip driver
in RH 5.0, but when I applied Jay Estrabrook's patch, the system did not
even recognize the chip. The problem was with the thin wire.
