Chapter 7: Networking Your Computer Troubleshooting Your Ethernet network Wired Ethernet network 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 router. ■ Make sure that all computers are plugged into a powered electrical outlet and turned on. ■ Make sure that the router 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. ■ 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. 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 opening your computer case, see "Opening the case" on page 49. For more information about your Ethernet card, see the documentation that came with your Ethernet card. Your wired Ethernet network is running slower than you expect ■ If your wired 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. 114 www.gateway.com

Troubleshooting Your Ethernet network

Wired Ethernet network

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 router.

■

Make sure that all computers are plugged into a powered electrical outlet and

turned on.

■

Make sure that the router 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.

■

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.

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 opening your computer case, see

“Opening the case” on page 49

. For more information about your Ethernet card,

see the documentation that came with your Ethernet card.

Your wired Ethernet network is running slower than you expect

■

If your wired 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.
