Common Problems and Solutions

Wireless-G PrintServer with Multifunction Printer Support

Appendix A: Troubleshooting

This appendix consists of “Common Problems and Solutions”. Provided are possible solutions to problems that

may occur during the installation and operation of the PrintServer. Read the descriptions below to help you solve

your problems. If you can’t find an answer here, check the Linksys website at

www.linksys.com

.

Common Problems and Solutions

1.

All the LEDs on the front of the PrintServer are not lit.

Check the power adapter and the connection to the electrical outlet.

2.

The PrintServer’s Power LED lights up orange or flashes continuously.

Reset the PrintServer. Unplug the power adapter and plug it back in, or press the

Reset

button on the back of

the PrintServer for approximately ten seconds.

3.

A printer connected to the PrintServer cannot print or prints garbage.

Do the following:

•

Check the cable connection between the PrintServer and printer.

•

Make sure the printer driver in the application program or Windows matches the printer.

•

Make sure the printer cable is not too long, less than 10 feet.

If there is still a printing issue, follow these steps:

1.

Double-click the PrintServer diagnostic icon.

2.

On the

PrintServer Info

screen, click the

Diagnostic

button.

3.

Follow the on-screen instructions.

4.

I am using DHCP, and the PrintServer gets an IP address conflict involving the PrintServer.

If the PrintServer is left powered on when the DHCP server, which is usually the network router, is powered

off, the PrintServer will retain its IP address without informing the DHCP server. Reset the PrintServer so it will

obtain a new IP address. This problem may also occur if you assigned a static IP address within the range

used by the DHCP server. If so, use another address NOT within the range used by the DHCP server.

5.

The PrintServer’s Ethernet LED is not lit.

Check your Ethernet network cable and make sure that the appropriate Ethernet or Link LED on your router or

switch is lit.

6.

To start over, I need to set the PrintServer to its factory default settings.

Unplug the PrintServer’s power adapter. Press the

Reset

button while you plug in the PrintServer’s power

adapter. Continue to hold the

Reset

button for ten seconds and then release it. This will reset the password,

wireless, and other settings on the PrintServer to the factory defaults. In other words, the PrintServer will

revert to its original factory configuration.

7.

I need to upgrade the firmware.

In order to upgrade the firmware with the latest features, follow these steps:

1.

Go to the Linksys website at

and download the latest firmware for the

PrintServer. Then extract the firmware file on your PC.

2.

Open the PrintServer’s web-based utility. Click

Status

and then

Device

.

3.

Click the

Upgrade

button, and follow the on-screen instructions.

Appendix B: Wireless Security

Security Precautions

Wireless-G PrintServer with Multifunction Printer Support

Appendix B: Wireless Security

Linksys wants to make wireless networking as safe and easy for you as possible. The current generation of

Linksys products provide several network security features, but they require specific action on your part for

implementation. So, keep the following in mind whenever you are setting up or using your wireless network.

Security Precautions

The following is a complete list of security precautions to take:

1.

Change the default SSID.

2.

Disable SSID Broadcast.

3.

Change the default password for the Administrator account.

4.

Enable MAC Address Filtering.

5.

Change the SSID periodically.

6.

Use the highest encryption algorithm possible. Use WPA if it is available. Please note that this may reduce

your network performance.

7.

Change the WEP encryption keys periodically.

To ensure network security, at least steps one through five should be followed.

Security Threats Facing Wireless Networks

Wireless networks are easy to find. Hackers know that in order to join a wireless network, wireless networking

products first listen for “beacon messages”. These messages can be easily decrypted and contain much of the

network’s information, such as the network’s SSID (Service Set Identifier). Here are the steps you can take:

Change the administrator’s password regularly.

With every wireless networking device you use, keep in mind

that network settings (SSID, WEP keys, etc.) are stored in its firmware. Your network administrator is the only

person who can change network settings. If a hacker gets a hold of the administrator’s password, he, too, can

change those settings. So, make it harder for a hacker to get that information. Change the administrator’s

password regularly.

NOTE:

Some of these security features are

available only through the network router or

access point. Refer to the router or access point’s

documentation for more information.

SSID.

There are several things to keep in mind about the SSID:

1.

Disable Broadcast

2.

Make it unique

3.

Change it often

Most wireless networking devices will give you the option of broadcasting the SSID. While this option may be

more convenient, it allows anyone to log into your wireless network. This includes hackers. So, don’t broadcast

the SSID.

Wireless networking products come with a default SSID set by the factory. (The Linksys default SSID is “linksys”.)

Hackers know these defaults and can check these against your network. Change your SSID to something unique

and not something related to your company or the networking products you use.

Change your SSID regularly so that any hackers who have gained access to your wireless network will have to

start from the beginning in trying to break in.

MAC Addresses.

Enable MAC Address filtering. MAC Address filtering will allow you to provide access to only

those wireless nodes with certain MAC Addresses. This makes it harder for a hacker to access your network with

a random MAC Address.

WEP Encryption.

Wired Equivalent Privacy (WEP) is often looked upon as a cure-all for wireless security

concerns. This is overstating WEP’s ability. Again, this can only provide enough security to make a hacker’s job

more difficult.

There are several ways that WEP can be maximized:

1.

Use the highest level of encryption possible

2.

Use “Shared Key” authentication

3.

Change your WEP key regularly

WPA.

Wi-Fi Protected Access (WPA) is the newest and best available standard in Wi-Fi security. WPA2 has

stronger encryption than WPA. WPA uses Temporal Key Integrity Protocol (TKIP), while WPA2 uses Advanced

Encryption System (AES).

These security recommendations should help keep your mind at ease while you are enjoying the most flexible

and convenient technology Linksys has to offer.

IMPORTANT:

Always remember that each device

in your wireless network MUST use the same

encryption method and encryption key or your

wireless network will not function properly.
