RT-AC1900P, and brand new windows 10 Home edition. I've turned on Samaba, SMBv1 and SMBv2, as well as guest login but I can't create new folders on the external USB drive. I've tried the drive in both USB ports, and can read files on the drive without a problem. When I try to create a new folder, or copy files to the drive, I get the "Error 0X80070032: The request is not supported" error. Nothing on my home network changed other than my PC. I'm running 384.19 and have even tried re-flashing back to non Merlin firmware. In "OptionalFeatures" SMB 1.0/CIFS client is checked. Any help?
