Linksys Wireless Router :: EA4500 - Network Drive Only Works Without Secure Folder Access

I'm trying map the USB hard drive connected to my EA4500 router as a network drive in Windows 7, and it works perfectly until I enable secure folder access on the router.
 
After enabling secure folder access, and not changing any other settings on the router I first unmount the drive since it was set up without credentials and doesn't work that way any more.  When I try to remap the drive I use the same address, but select "Connect using different credentials"  When it prompts me for the log in info I try using the router admin account, but it fails to connect.   Windows network diagnostics tells me the device refused the connection.  I proceeded to set up an account on the router under the folder access settings with the same username, and password I use on my computer, and tried to connect it without checking "Connect using different credentials" (And typing them in manually if that matters) with the same results.
 
Even with secure folder access enabled I can still reach the drive just fine by typing "ftp://192.168.1.1/" into file explorer.  It prompts me for a username and password, I put in the admin credentials, and I'm in.  Even the account I created with the same username/password as my computer works this way.
 
After disabling secure folder access everything works perfectly fine again...  I would MUCH rather do this with it though.
 
Following these directions: [URL] When clicking the browse button the router shows up when secure folder access is disabled, but does not after it is enabled.  I've looked through my windows sharing settings, and haven't noticed anything that should cause problems, pretty much everything is enabled.  I've also tried turning off my firewall with no success.
