What does /sbin/ifconfig say about the network card(s)?  Did you set
the new card up after installing it (system-config-network)?  Are
there any error messages in dmesg or /var/log/messages?  Are the cards
recognized and using an appropriate driver?  How are you testing?  Is
your route setup correctly?
It sounds like you have tried a lot with hardware, but you also need
software (the drivers and configuration) in order to talk the the
hardware.  Ideally it would all just work, but something is apparently
getting confused.  Do you have a NIC known to work with Linux?
