Lorenceo: The device terminating your connection will likely end up being the main bottleneck for speeds. Going for the cheapest device that'll work is IMO a bit short sighted, but each to their own.
The C9, NF8AC and C2 will all work on BP UFB. The C9 is the most capable of them all.
Fair point, and I totally agree. On the other hand, buying a Ferrari when I just want to pop down to the shops seems like overkill. I was just trying to get a feel for their capabilities. It's a shame the C9 is not wall-mountable. :(
