I did have an issue with my HP Laserjet M276NW printer immediately following my update to 4180 (and after configuring it post factory reset - By the way I'd connected via telnet and did it via the "nvram erase" method, not using the factory reset method in the GUI if that matters) but rebooted the printer and it has been fine since. I use WPA2-Personal and I use the Smart Connect WiFi settings on the router.
