Want to say it's garbage that different versions of the same product have different capabilities.  How are we supposed to know what version we are buying when making a purchase.  I purchased through Dell and nowhere do they put a version.  I have v2.6 and when I go to the TPLink site and download the user guide for my specific version (v2.6) and it says it should have VPN capabilities but it's not in my app.  Why does this feature no longer exist and why are there differences in the versions?
