Troubleshooting Suggestions

To use this section, find the problem statement that is closest to your problem, then try each bulleted item one at a time until your problem is fixed. If the suggestions do not solve your problem, contact HP—see the support guide for more information.

If you are experiencing problems with the projector, see the projector manual.

Connection problems

If you cannot connect to the projector in Wireless Presenter-to-Go:

Be sure the projector is plugged in and 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).

If you can connect to the projector using a Web browser and

the projector’s wired or wireless IP address, the network settings and connections are good for that connection. If you cannot connect using a Web browser, the network settings might be wrong—see the next problem.
