Error 321 – Router setup
What is Error 321 ?
You get this error 321 when you try to install the router using the CD.
This error shows that your computer is not connected to the router or the connection between the router and the computer is not working. When you run the CD , it will ask you to connect the computer and the modem to the router with the cable. You will see all the lights lit up on the router according to the instructions but still you will get error 321.
In this case you will need to check the firewall settings of the computer. If there is any firewall installed on the computer, then turn it OFF. Make sure that the Local area connection on the computer is not Disabled. The local area connection should not have any static IP address assigned. If there is any then set the IP address to automatic.
Try to run the CD again and see if that works. If that doesn’t work then try to setup your router without the CD. You can setup your router manually.
How to setup router without installation CD:
Connect the main computer to the Ethernet port on the router. Connect the modem to the Internet port on the router. Check the status of the light.
Open the setup page of the router and change the Internet connection settings manually. The setup page of the router is the place where you can change the settings of the router.
Once your main computer is able to access the Internet, create a wireless network for your wireless computers and devices.

That is correct. Error 321 comes up when the computer is not connected properly. Some times it may be because of firewalls on your computer also.
I have WRT120N and getting the same error 321. I tried to reset and reconfigure it but same thing. How do I change the settings manually?
