hsdpa router 可吾可以boardband連出街?

I am using the D Link DIR-451 HSDPA wifi router. When I bought it 6 months ago, the reseller said there will be firmware to make this router support broadband. But I have not checked the firmware for long time. In fact, I don't even remember which firmware I am using now and I don't want to change the firmware to support broadband coz I don't have this need. You can check it out for more detail if you are interested to D Link product.
