ii have an HP Officejet Pro 8620 printer; just got a new Hitron Modem from my cable company, and now my wonderful printer won’t print!! It says I am no longer connected to the network. I called Cable One, and they said to call HP, because it is a printer issue. Help!! I can’t use my printer!
To begin make sure the printer and wireless router are at least 6 feet apart from each other.
Reset your printer back to Network Defaults as the printer settings are still set to the previous modem. Then run the Wireless Setup Wizard to connect. Both of which can be accessed from the printer front panel or computer. If there is no front panel on the printer for configuration, you can use your Printer USB cable to connect. You can also try the WPS method if your router/printer supports it, try this method only if the Wizard or Printer USB cable is not available.
Set the router to a fixed wireless channel like 1, 6 or 11, never ‘auto’. Try channel 1 first then the other channels, one at a time.
The router must use a 2.4Ghz SSID band enabled to communicate with the printer and set a different name than your 5.0Ghz SSID band in your router.
