Network Connection Problems

The following solutions may help if you encounter problems when using a network card for network connections. Additional troubleshooting information is available in Connections Help on the device and ActiveSync Help on the desktop PC.

•Verify that your NIC is compatible with the hp Jornada 560 series personal digital assistant and that you have installed the proper drivers for the hp Jornada.

•In the properties for your network adapter, ensure that you have properly configured the IP settings, and the addresses of your DNS servers and/or WINS servers. Check with your network administrator to determine the proper settings.

•Verify that you have added necessary server information. On the Start menu, tap Settings. On the Connections tab, tap Network. Tap your installed adapter (usually your Ethernet card's name) and enter any necessary information. Most networks use DHCP to assign IP addresses dynamically; you should not have to change or enter an IP address settings unless your network administrator instructs you to do so.

•If Network Connection is not listed as a connection method in the ActiveSync dialog box when starting synchronization, wait a few minutes and try again. Also, if synchronization does not start right away, the network is probably busy, and it may take a minute for your device to connect to the network.

•Verify with your network administrator that your user name and password are correct.

•Verify with your network administrator that the network you are trying to connect to is available, or try to connect to it from another computer.
