Specs: Windows 7
My HP envy 7640 does not connect by wireless to my computer. It started with the scanner not connecting. I removed the software from the computer and tried to reinstall it. It is still not communicating with my printer

Is your printer Connected (wirelessly) to your router? If your wireless network is secured (WPA2??), enter the passphrase on the printer, or use the WPS procedure to have your printer connect with the router.

See the printer & router manual on how to use the WPS procedure.

I had a similar problem. My printer hp Photosmart 6520 would randomly disconnect. The message I would get is "Scan to computer no longer available". The problem was the modem/router losing internet and causing the network to crash. After a firmware update to the modem/router from my ISP the problem no longer exists. You could go to and reinstall the drivers for Windows 7. Another way to fool the computer is to uninstall your wifi card and/or your COM port for the printer in device manager. Windows will automatically detect it again, and either self install or let you choose to search in Windows Update. If your modem/router and card is working you can look in your router/modem (, what ever username and password you made for it, default: admin, password or admin, admin) in the wireless settings, and find either the IP(Wired) address or MAC(Wireless) address through the DCHP client list. Enter it into your address bar and communicate directly with the printer from your computer. Easier way is to plug a USB cable into the computer and see if it is the printer itself. This is more process of elimination.

I don't need to be right, but I am never wrong.

You do not make it clear the following information:
Is your printer a wireless printer?
Is your printer hard wired to the network and you are printing wirelessly through the network?
Is the printer connected to the network via a USB connection to one computer and then shared?
Have you tried to reset your modem and router? Even if they work for some devices resetting them often makes other devices work again.
Have you tried the printer via USB connection to a computer to see if there is any unrelated printing problems that could be the cause of the non-printing?

You have to be a little bit crazy to keep you from going insane.
