In terms of features, D-Link’s DIR-855 came the closest to matching Netgear’s routerlicious WNDR3700. It’s a simultaneous dual-band model that allows you to run guest networks on either the 2.4- or 5GHz frequencies, it provides a USB port for sharing either a printer or a storage device, it’s equipped with three removable/upgradeable antennas, it sports an OLED display, and its firmware is a tweaker’s paradise.
But the benchmark performance we experienced with the DIR-855’s 2.4GHz radio in no way justifies its astronomically high street price of $240. Netgear’s WNDR3700 V1 spanked the DIR-855 on both frequency bands, has almost as many features, and costs $90 less than D-Link’s router.
You can attach either a printer or a USB storage device to the DIR-855's single USB port, but you'll need to run D-Link's SharePort utility on any client that needs to access it.
The DIR-855’s 2.4GHz radio scored fourth or fifth everywhere except at our outdoor location, where it placed first. Its 5GHz radio performed better, coming in second (behind the WNDR3700) in our two close-range tests, and third and fourth in two other tests.
On the bright side, D-Link’s firmware boasts more customizable settings than any other router in this field. You can configure both radios to operate on a schedule, so you can shut off your entire wireless network when you’re away from home (with independent schedules for your guest networks), you can grant or deny guests access to your LAN, and more. But in the final analysis, we’d be a lot more impressed if the DIR-855 was a whole lot faster and much cheaper.
