My new MF8380Cdw functions well when it is connected through USB. However, I have not made it to print/scan through wired LAN connection. I have tried on multiple HP notebooks with Win7 64-bit. I have tried turning Windows firewall off. I have McAfee VirusScan Enterprise 8.7i installed which does have a firewall with it. I have also tried turning off the OAS. With all the possible combinations tried, so far no luck.
