FTP/SMB, WTF? smh!!

I've been testing to see if just plugging an external flash/solidstate USB storage unit to the modem would be enough for us to share docs (pdfs and jpegs mostly and some music) at home. You know, instead of forking out bigger bucks for a NAS unit b/c we really don't need to access it from outside.

So I succeeded in that I can see the test USB stick from the web browser, but I can't access it from the file explorer. what the hell am i doing wrong?

edit: modem is an Alcatel I-240W
