There's nothing wrong with your current setup.

In my opinion the Superhub is currently pointless and unnecessary. As a modem, it uses twice as much power as your current one, and is not needed for the service you are on. If/when it becomes absolutely necessary, or your service degrades as a result of not having one, VM should provide you with a replacement free of charge.

As a wireless router, many people have said the wireless on the Superhub is sub-par, and sometimes average. Your current router is already wireless-N and as good as the Superhub's wireless (barring lack of 5Ghz which is just about pointless on it anyway). It'll either perform about the same or worse, but is very unlikely to be better. You can get far better wireless performance by keeping your current modem and buying your own router. So again, no point getting the Superhub when the VMNG300 is a tried and tested, well regarded, reliable, and proven piece of equipment.
