I have asked some colleagues, and most of the issues they have seen after the Windows 10 upgrade were the user account password has changed or the device was set to DHCP and the device IP address changed causing issues or the scan path was incorrect.
So my recommendation is ensure that the device path and password is correct and then I’d look at the OS:
Yeah, I also am trying to scan to my NAS.
But I can't even find a network. I can't type in any path. Thats the problem.
This user has had success changing the frequency to 2.4GHz for scanning to the 6515, so it would be worth a shot.
The MFP is connected to Ethernet. And i try with Wifi same issue....
Again, is a issue with firmware
