With some of the NBN plans getting a speed bump soon I was looking for a new router with gigabit ports. This is the cheapest one I could find with gigabit ethernet ports.

Surcharges: 0% direct deposit, 0.9% card, 1% on all other payments.
There is more to it than Gigabit ports. Your router needs a fast CPU and have enough RAM.
What speed are you changing to?
