Firmware Version - This field displays the current firmware version of the Presentation Player. Firmware upgrades, when available, may be down- loaded from the Linksys web site at no charge. If you are not experiencing any problems with the Presentation Player, you should not upgrade the firmware. Make sure to review the release notes of any firmware version before attempting an upgrade.

System Name - This is a common name that you assign to the Presentation Player. This field is limited to 32 characters. By default, four alphanumer- ic characters follow the device name. These represent the last four charac- ters of the Presentation Player's MAC (Ethernet) address. The MAC address is printed on the bottom of the Presentation Player. Assigning unique and memorable names is helpful, especially if you are employing multiple Presentation devices on the same network.

Presentation Player

IP Address - This is the Internet Protocol Address that is assigned to the Presentation Player. Click Obtain an IP Address Automatically or Specify an IP Address. Choose Obtain an IP Address Automatically to allow your Presentation Player to automatically obtain a dynamic IP address from a DHCP server. Or, choose Specify an IP Address where you will assign all the devices a permanent IP Address and enter the fixed IP address in the fields provided. Then, enter the Subnet Mask into the fields provided. No DHCP changes will take effect until the Presentation Player has been pow- ered down and powered up again. The IP Address will only be used to remotely configure or control the Presentation Player. You need not recon- figure it if you are traveling to remote locations and plan to use the hand- held remote control.

Wireless - This section contains all of your wireless settings.

•SSID - This stands for Service Set IDentifier. The SSID, also called the Network Name, is a unique name that identifies a wireless network. In order to connect to the Presentation Player, all of your wireless comput- er's settings must be identical to the SSID you define here. The SSID is case sensitive, must not exceed 30 characters, including WPG12-, but may consist of any keyboard character. Make sure this setting is the same for all wireless nodes communicating with the Presentation Player. You should change the default SSID of "linksys" to a name unique to your network.

Note: WPG12- is a permanent part of the SSID for this device. You many enter any characters following WPG12-, but wireless PCs must have the full SSID, including WPG12-, to communicate with the Presentation Player. In most cases, the Control Utility will configure this setting for you.

•Channel - Each Access Point and/or Presentation Player on your net- work should be assigned a unique channel. The channel is a common number that sets the actual frequency this particular device will use to communicate with wireless clients. For example, TV and Radio Stations refer to particular channels, which are actually frequencies at which radio waves are transmitted.

If you experience poor performance, you may be encountering interfer- ence from another wireless device. Try changing the channel, as this may eliminate interference and increase performance. Channels 1, 6 and 11 are preferred.
