Ethernet
You cannot see the other computers on your network
•
Make sure that your Ethernet cable is plugged into the
Ethernet jack on your computer. Make sure that the
other end is plugged into a network router, switch, hub,
or other network device.
•
Make sure that all computers are plugged into a
powered electrical outlet and turned on.
•
Make sure that the router (if you are using one) is
plugged into a powered electrical outlet and turned on.
Most routers have lights that indicate they are working.
For more information, see
the documentation that came
with your router.
•
If you are using a router, try rebooting it by unplugging
its power cord, waiting five seconds, then plugging it
back in.
•
Make sure that all computers on your network have the
same workgroup name.
•
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.
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.
