@lthielster I've had a chance to explore the NAS function on the TripMate, and had no trouble connecting to a NTFS 16GB USB stick plugged in it, from a Windows 7 Pro system, following a mix of instructions in the manual and from the HTG article.
It didn't matter whether I powered on the TripMate or inserted the USB stick first (despite what it says in the manual).
The PC was set up to use DHCP to connect to wifi. I found the TripMate's wifi and connecxted to it, using the default key 11111111.
Then I opened Explorer at 'Network', and typed
\\tm01\ in the address bar. The network credentials dialog box appeared, and I entered the default username viz admin, and left the password field blank (the default). Bingo!
The drive showed up as 'USBDisk1_Volume1', and I could read and write to it (and its subfolders).
