Testing your Computer Network
After all the setup in our network switches, plugged in all the cables, and configured all our computers. One task remains before you can declare our network finished: We must verify that the networks work as expected.
Here are some few simple tests you can conduct to ensure the functionality of the network.
Check the Physical Connection
Check the Physical Connection
Check the link light - the little red or green light next to RJ-45 port. Check this light both on computer and the switch or router the computer is plugged into. If this light is not on, we have a connection problem--mostly a bad cable.
Verify that we can log in
Verify that we can log in
To ensure the physical connections are good, we should attempt to log on to each of our network computers using a valid domain user account.
Check the network configuration
Check the network configuration
Click the start button, open cmd and press enter. Then, enter the command ipconfig/all press enter.
This command will spit our numerous lines of information but the line we are looking for shoul be the IPV4 adress
Ping another Computer (LAN )
Ping another Computer (LAN )
Open the Cmd. Then, enter command ping followed by the IP adress of the other computer. For example ping 192.168.1.1. You can see that there is a reply indicating a good connection.
Ping a Website
Ping a Website
(WAN)
(WAN)
Same as the LAN. CMD then enter the IP adress of the website online
for example Google.com we may use the command ping google.com -t.
NOTE: Make sure that that the router/modem has its connectivity to ping online it will not work offline.
