Older/cheaper TP-Link products allow the connected FTP drive to have separate "read" and "write" accounts.

I can open up the device to allow Internet access... and only give friends/family the "read" password account.

I can have a different name/password for full "write" access.

Did they remove all of that functionality from the AC1750 C8?

Why did I buy a newer/faster router that I now can't use?

I do *NOT* want to set up a separate Linux FTP server... nor mess with Windows permissions.

I need to do all this INSIDE THE ROUTER.
