Every HP printer I have in my environment will no longer connect to the network. It all started a couple of weeks ago. I have replaced WAPs, network switches and re-configured the network. The printers will not pull an IP address via DHCP. (169.254.15.26) I have even tried to do a MAC reservations through the Sonicwall Router. I have tried manually setting up the IP and it will finally pass all the wireless tests except internet. When printing the Network Page, it will show PASS on all sections except for connection to internet. This is only affecting the HP printers on site, the other brands of printers are all connected and available to print.
I ended up having to create another 2.4 SSID just for the printers with simple WPA encryption. It turns out that if you are using Araknis WAPs, there is a problem with the 5ghz and WPA2-PSK encryption and the printers.
