I've had trouble getting the Archer VR900v to work with my German Vodafone VDSL (100 MBit/s) connection, and judging from a few other questions around the net, I'm not the only one. It turns out the two "Vodafone" options the router's web interface offers both don't work if you enter the user name as it is provided by Vodafone. You have to prefix the username with "vodafone-vdsl.komplett/", then it works.

I've described it in more detail on my blog (in German): https://patrick-nagel.net/blog/archives/569

Maybe TP-Link could add this prefix to the "Vodafone/Arcor_VDSL(DT Resale)" option in a future firmware version?
