Great performance, though you can't run on both bands at once.
This cable router is an upgrade from Buffalo’s older Nfinity model.
It supports dual band, but unlike the other dual band routers on test it can only run at either 2.4GHz or 5GHz, not both. That means the 5GHz option is no use unless all your devices support it.
The Giga is as easy to set up as its predecessor using Buffalo’s AOSS software. Press the large AOSS button, select AOSS in the client software, and the AirStation is online in less than a minute. It doesn’t get more complicated than that, and you don’t need to look at the unintuitive web interface. This has all the necessary security settings, but despite helpful descriptions, locating them is far from straightforward.
The Nfinity offers basic QoS and support for dynamic DNS. Its biggest strength is its performance. Although we noticed a big drop at 25 metres to 7.12Mbit/sec with our Centrino laptop, with a Buffalo AirStation USB adapter the Nfinity reached 44.29Mbit/sec at 15 metres from our PC, and managed 25.25Mbit/sec at 25 metres.
The Nfinity is one of the cheapest dual band routers, keeping in mind that you can’t run both frequencies at once. With Gigabit Ethernet too, it’s a good choice for a fast network.
