Fixing the System

If you cannot connect to the projector using a Web browser:

❏Be sure the projector is plugged in and the main disconnect switch is turned on.

❏If you are using a wireless connection on the projector, be sure the projector is turned on.

❏If you are using a wireless connection on your computer or on the projector, be sure the computer or projector is within range of each other or the wireless access point. They should be within about 50 m (160 ft) when indoors (the maximum range is about five times as far outdoors).

❏Be sure that you are using the correct IP address. If you are using a wired network connection, the projector’s IP address is shown in the on-screen menu on the projector. If you are using a wireless connection, the wireless IP address is shown in the on-screen menu at Quick choice > Wireless Presenter.

❏If you can connect using Wireless Presenter-to-Go, the network settings and connections are good. The projector’s IP address or hostname you are using in the browser is probably incorrect.

❏Check whether the projector’s IP address is shown in the on-screen menu. If the projector is set to use a DHCP server and no DHCP server is available, no IP address is set for the projector. You can disable DHCP and manually set an IP address, or you can contact the network administrator for a valid TCP/IP network configuration, then set up the projector accordingly.

❏Contact your network administrator to determine the proper settings for your network.

❏Turn off the projector, then remove power for at least 15 seconds. This restarts the module.

❏If another computer can connect to your projector, check your computer at the “Computer—wired connection” or “Computer—wireless connection” on page 55. If another computer cannot connect to your projector or if your computer can connect to another projector, check your projector at “Projector—wired connection” or “Projector—wireless connection” on page 55.
