Hi Jeff- the Pentium 2 is wired, The P4 is wireless

I got the specs for my ethernet card for the wired part of the network

Test Configuration
Product Name/Model/Rev Realtek RTL8139/810X Family Fast
Ethernet/Rev.D
Specification Version/Rev C HSM v1.11
Adapter Bus Type PCI
Adapter Bus Width 32
Adapter Transfer Method Bus Mastering
Communications Mode Half/Full Duplex
Connector RJ-45
Error Capturing N/S
Multicast Mode YES
Promiscuous Mode YES
Topology Ethernet
Transmission Line Speed 10/100 Mbps

Is this an appropriate card for my network? Can any settings be
tweaked to get a faster transfer rate?

Thanks, I will check this site out

Again, many thanks Jeff- this is a wealth of information and is
greatly appreciated.
