Dual-Band, Two-Radio Buffalo Router Reviewed

By Glenn Fleishman

Tim Higgins takes apart the Buffalo Wireless-N Nfiniti Dual Band with gigabit Ethernet over at SmallNetBuilder: As Higgins notes in his review, even though dual-band Draft N routers are on the market, Buffalo’s is the first with two distinct radio mechanisms that allow simultaneous use of 2.4 GHz and 5 GHz. This version isn’t yet compliant with Draft 1.10 approved in January, nor Draft 2.0, approved yesterday. The mechanisms for co-existence with older 802.11b/g networks in 2.4 GHz just isn’t there yet, and a lot of other small problems, like a lack of automatic downshifting from 40 MHz to 20 MHz, cause problems with range.

The gigabit Ethernet even seems to be a problem, with a bottleneck in LAN to WAN routing: Higgins saw just 200 Mbps of throughput in testing over Ethernet to Ethernet. When I tested the AirPort Extreme Base Station, I was able to achieve just 60 Mbps on their 100 Mbps Ethernet LAN-to-WAN or WAN-to-LAN bridge. Intra-LAN was 94 Mbps with Ethernet.

The unit costs $250 and it’s the only thing on the market to have its distinct set of features. But Higgins’s takeaway is that it’s not time to buy it or any Draft N gear because he wants Draft 1.10/2.0 to be implemented in firmware before making that determination. Based on this review, that’s a reasonable stance because the weak areas in the device seem to have already be worked out in the draft, and a more mature version of the firmware could solve other problems.
