I have an Archer C1200 as my NBN modem and have been using the USB attached disk over WiFi. Now that Apple iOS 13.2 allows access to NATs (over WiFi) I would like to connect using the iOS Files app but although the app connects to the Archer and finds the correct primary folder on the attached disk, it cannot access any files. A search on the web seems to suggest the Archer needs to be using SMB 2 or higher, whatever that means, for me to actually access files on the attached disk.
Please help.
