•

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.
