Yes, it's working on the Netgear WNDR3700, it's working on a FileZilla Server, it's working on a QNAP FTP server. And it's NOT working on a new Netgear AC1900/R7000 router. I cannot get it because I can access the FTP stick with a FileZilla client. No problem creating folders with the FileZilla client. I guess the CAM is the problem. Why are those two devices in war with each other? The CAM is able to create files on the USB stick in the AC1900, with FTP. But no folders. I hate this problem and I cannot fix it. Netgear tells the router is okay because a FileZilla client is working (creating files and folders). And D-Link is doing nothing, no response, no help!!!!! I guess I must buy another brand IP CAM. Service of D-Link is Zero!!
