• Make sure that all computers are using
the same Subnet Mask.
• If you assigned IP addresses to the
computers, make sure that all computers
have different IP addresses. For home
networks, IP addresses should be
192.168.N.N where N is a number you
assign between 0 and 254. The first N
should be the same for all computers on
your network and the second N should be
different for all computers on your
network.
The computer does not recognize an add-in
Ethernet card
• Shut down and restart your computer.
• Make sure that you have installed the
required software. For more information,
see the documentation that came with
your Ethernet card.
• Reseat the card. For more information
about your Ethernet card, see the
documentation that came with your
Ethernet card.
Your Ethernet network is running slower than
you expect
• If your Ethernet network is running
slower than you expect, check the speed
of each Ethernet component. For best
results, all Ethernet components should
be standard Ethernet (10 Mbps), Fast
Ethernet (100 Mbps or 10/100 Mbps), or
Gigabit Ethernet (1000 Mbps or
10/100/1000 Mbps). A mixture of
Ethernet, Fast Ethernet, and Gigabit
Ethernet components will result in your
network running at the slowest
component speed.
