If you're having trouble connecting your HP Officejet Pro 6978 to your wifi, you should check the WPS button on your Netgear router. The WPS (wifi Protected Setup) button is a convenient way to quickly connect your printer to your home network without having to manually enter your network's security information. The WPS button can be found on most modern Netgear routers, typically on the back or side of the router. To use it, press and hold the WPS button for five seconds until the light on the router begins to flash. Then, on your HP Officejet Pro 6978, locate the WPS button and press it for two seconds. The printer will search for any available networks, and once it finds yours, it will automatically connect. It's important to note that if you have enabled security on your wireless network, like WPA2-Personal, then the printer may require you to enter the security key before it can connect. In this case, you'll need to refer to your router's manual to find out how to access the security settings. This will fix the issue HP Officejet pro 6978 won't connect to wifi.
