The first thing in line needs to be modem ONLY (i.e. not Hub or Super Hub). Then a router which is DD-WRT capable can be connected, giving lots of network options almost no home routers are capable of.
Disabling the wireless of the Super Hub doesn't turn it into a modem, it's still a modem/router just not a wireless one.
The WNR2000 being supplied isn't a big deal, honestly. It's a reasonable unit for something so cheap but the range isn't great. The D-Link 615 would do just as well, perhaps better, as all hardware revisions are supported by DD-WRT whereas with the WNR2000 only v2 is.
Seeing as not all comments about it are negative I'm more than willing to concede I was one of (guessing) 20-40% of people who got a duff one, but even if it worked perfectly it still wouldn't be good enough for what I and several other power users need.
Seperate modem then router is the way to go, and VM as a company should be smart enough to realise that. You pay extra for the premium broadband packages, you should be able to run the network the way you want more or less.
