HP Envy 6455e stays offline

[Tcullen]

My HP Envy 6455e will go to offline after a few hours of being idle.  If it stays idle for more than 24 hours, it will not come back online unless you delete the device and readd it to the computer.  This is not helpful at all.  If you want to use this on a wifi connection it will not be very usable having to readd the printer every time you want to print something.  I have been through this with the support engineers and one of them told it was a windows problem.

Hi @Tcullen,

Update the FIRMWARE

Check for network and connection issues if you cannot print or scan with a wireless HP printer.

Restart devices

1. Restart your computer or mobile device, printer, and router to clear any error states.
2. Disconnect your computer or mobile device from the network name (SSID), and then reconnect it to the same network name your printer is connected to.
3. If the printer is available and has a ready status, the issue is resolved. You do not need to continue troubleshooting.
4. Press the Power button to turn off the printer. If the printer does not turn off, disconnect the power cord from the printer and from the power source.
5. Turn off the computer or mobile device that the printer was set up with.
6. Restart the router.
7. Reconnect the power cord to the printer and to a wall outlet.
8. NOTE:
9. HP recommends plugging the printer directly into a wall outlet.
10. Turn on the computer or mobile device.
11. Check the connection to make sure the same network is used by the printer and the device.
12. Computer or mobile device: Open the list of available networks and make sure it is connected to the correct network.
13. Printer: Check the Wireless light on the control panel. If it is solid blue the printer is connected.

Check the printer and network connections

1. Identify issues with Wi-Fi connections that can cause the printer to be unavailable or not found by your computer or mobile device.
2. Perform the following tasks in the order given. Use the printer after each task to see if the issue is resolved.
3. Move the printer within 8 m (26 ft) of the router or range extender, and then check the Wireless light . If it is solid blue, the printer is connected to the network. If the light is off or flashing, the printer is not connected. Go to HP printer setup (Wi-Fi network) for more information.
4. Open the list of available networks on the computer or mobile device and make sure it is connected to the correct network. A check mark or Connected status displays next to the network name when connected. Do not connect to DIRECT-xx-HP [your printer model name].
5. NOTE:
6. A printer connection cannot be established over public or guest networks that require a guest login or confirmation of use, such as networks used in schools, hotels, or coffee shops.
7. Check the Wi-Fi signal strength on the computer or mobile device. If the wireless icon shows a weak signal , move closer to the router or range extender until a strong signal displays . Walls, metal bookcases, and electronics that emit radio signals can weaken the signal.
8. Open a website to confirm the internet is working. If page load time is slow or intermittent, turn off or pause any other streaming devices connected to the network. If necessary, contact your internet service provider to check if the service is down.
9. Make sure the printer is not connected to a computer with a USB cable. A USB connection can block Wi-Fi setup and disables the printer internet connection required for HP Instant Ink.
10. Check your router support website or documentation to make sure it meets the following requirements.
11. Many routers operate in both 2.4 GHz and 5.0 GHz frequency bands, but not all HP printers support both bands. Make sure the 2.4 GHz band is enabled and broadcasting. If the router broadcasts separate network names (SSIDs) for each band, connect the printer to the 2.4 GHz SSID. If the printer supports 5.0 GHz, connect it to the 5.0 GHz SSID.
12. Bonjour support (Mac): HP recommends routers that support Bonjour, Apple's network discovery software. Connecting with Bonjour is the best way to find the printer and support wireless printing.
