My HP 8600 is not connecting to my WiFi network.

[WC_Marc]

My HP 8600 is not connecting to my WiFi network. Getting an error message when entering the WPA key on Test Results that reads "More than once access point has been found that matches your wireless network name (SSID)".   I have a router with both 2.4 and 5 GHZ operating under same SSID name.   It  has been connecting under the network configuration for over a year, but now all of the sudden it is not working. Can someone assist?

Welcome to the HP support community.

Reset the printer's network settings

1. Touch (right arrow), touch Setup, and then touch Network. Touch Restore Network Defaults, and then select Yes. A message appears stating that the network defaults have been restored.

2. Touch (right arrow), touch Setup, select Reports, and then select Print Network Configuration Page to print the network configuration page and verify that the network settings have been reset.

Set up the printer using the Wireless Setup Wizard

The Wireless Setup Wizard provides an easy way to set up and manage a wireless connection to your printer from the printer control panel.

1. Set up the printer hardware. See the getting started guide or the setup poster that came with your printer.

2. On the printer control panel, touch (right arrow), touch Setup, and then touch Network.

3. Touch Wireless, touch Wireless Setup Wizard, and then touch OK.

4. Follow the display instructions to complete the setup.

I hope that helps.
