HP 6500 - E709n, 6500 - E709q Guidelines for reducing interference on a wireless network, Method

Chapter 8

Connect the device using an ad hoc wireless network connection

Method 1

1.Turn on wireless in your computer and in the device.

2.On your computer, connect to the network name (SSID) “hpsetup“. (This network name is the default, ad hoc network created by the HP device.)

NOTE: If your HP device was previously configured for a different network, you can restore the network defaults to enable the device to use “hpsetup“. To restore the network defaults complete the following steps:

Reset the administrator password and network settings: Select Setup, select Network, and then select Restore Network Defaults. For more information, see General troubleshooting tips and resources.

Guidelines for reducing interference on a wireless network

The following tips will help reduce the chances for interference in a wireless network:

•Keep the wireless devices away from large metal objects, such as filing cabinets, and other electromagnetic devices, such as microwaves and cordless telephones, as these objects can disrupt radio signals.

•Keep the wireless devices away from large masonry structures and other building structures as these objects can absorb radio waves and lower signal strength.

•For an infrastructure network, position the WAP in a central location in line of sight with the wireless devices on the network.

•Keep all wireless devices on the network within range of one another.

Configure your firewall to work with HP devices

A personal firewall, which is security software running on your computer, can block network communication between your HP device and your computer.

If you are having problems such as:

•Printer not found when installing HP software

•Unable to print, print job stuck in queue or printer goes offline

•Scan communication errors or scanner busy messages

•Unable to see printer status on your computer

The firewall might be preventing your HP device from notifying computers on your network where it can be found. If the HP software cannot find the HP device during installation (and you know the HP device is on the network), or you have already successfully installed HP software and experience problems, try the following:

1.If you are using a computer running Windows, in the firewall configuration utility, look for an option to trust computers on the local subnet (sometimes called the “scope“ or “zone“). By trusting all computers on the local subnet, computers and devices in your office can communicate with each other while still being protected from the internet. This is the easiest approach to use.

2.If you do not have the option to trust computers on the local subnet, add incoming UDP port 427 to your firewall’s list of allowed ports.
