Using a wireless network

While you are using HP Wireless Presenter-to-Go, you have access to only one wireless network: the infrastructure or ad-hoc network that connects to the projector. If you use a different wireless network to connect to other computers or to the internet, you do not have access to those connections whenever HP Wireless Presenter-to-Go is running. This software disables wireless network services while it is running and restores those services when it closes. If you want to change to your normal wireless network or view available networks, you should exit HP Wireless Presenter-to-Go first.

Making a connection with a personal firewall

If your computer has personal firewall protection installed, you can still make a network connection to a projector.

•If you disable the firewall software, available projectors are listed when you start HP Wireless Presenter-to-Go.

•If you do not disable the firewall software, no projectors are listed, but you can click Other Projector, enter the projector's network settings, and make a connection.

Making a wireless connection

You cannot make a wireless connection to the projector while it is turned off (Standby mode). The projector must be turned on to use the CompactFlash wireless card.

Making a direct network connection

If you need to make a direct network connection between a computer and the projector, you may need to use a cross-over network cable, not a standard network cable. You might need such a connection when you are upgrading firmware without having access to a standard network. If you make such a connection, you must configure the network settings on the computer and projector.

•On the computer, open the properties for the network connection and edit the TCP/IP settings. Disable the automatic addressing (DHCP) and set or write down the IP address of the computer. For example, you could set the IP address to 10.2.3.4.

•On the projector, open the on-screen menu and go to Setup > Network. Disable the DHCP option, then set the IP address to a value that differs from the computer
