Solving network problems (some models only)

NOTE: After correcting any of the following, run the installation program again.

General network troubleshooting

•If you are unable to install the device software, verify that:

•All cable connections to the computer and the device are secure.

•The network is operational and the network hub is turned on.

•All applications, including virus protection programs, spyware protection programs, and firewalls, are closed or disabled for computers running Windows.

•Make sure the device is installed on the same subnet as the computers that will be using the device.

•If the installation program cannot discover the device, print the Network configuration page (see “To print the Network configuration page” on page 28), and enter the IP address manually in the installation program.

•If you are using a computer running Windows, make sure that the network ports created in the device driver match the device IP address:

1)Print the device’s Network configuration page.

2)From the Windows desktop, click Start,

point to Settings, and then click Printers or Printers and Faxes.

Or

Click Start, click Control Panel, and then double- click Printers.

3)Right-click the device icon, click Properties, and then click the Ports tab.

Or

Right-click the device icon, click Run as administrator, click Properties, click Continue, and then click the Ports tab.

4)Select the TCP/IP port for the device, and then click Configure Port.

5)Compare the IP address listed in the dialog box and make sure it matches the IP address listed on the Network configuration page. If the

IP addresses are different, change the IP address in the dialog box to match the address on the Network configuration page.

6)Click OK twice to save the settings and close the dialog boxes.

Problems connecting to a wired network

• If the Link light on the network connector does not
turn on, make sure that all of the “General network
troubleshooting” conditions listed above are met.	English
• Though it is not recommended that you assign the
device with a static IP address, you might resolve
some installation problems (such as a conflict with a
personal firewall) by doing so. For more information,
see the onscreen user guide on the Starter CD.

Solving wireless problems (some models only)

If the device is unable to communicate with the network after completing the wireless setup and software installation, perform one or more of the following tasks.

Check the wireless communication settings

•Make sure the computer’s wireless card is set to the correct wireless profile. A wireless profile is a set of network settings unique to a given network. A single wireless card might have several wireless profiles (for example, one for a home network and one for an office network). Open the Configuration utility for the network card installed on your computer, and ensure that the profile selected is the profile for the device’s network.

•Make sure the device’s network settings match those of your network. Do one of the following to find the settings for your network:

•Infrastructure communication: Open the wireless access point’s (WAP) Configuration utility.

•Ad hoc communication: Open the Configuration utility for the network card installed in your computer.

•Compare the network’s settings to those on the device’s Network configuration page (see “To print the Network configuration page” on page 28), and note any differences. Possible problems include the following:
