The DIR-615 didn't blow us away with its performance but more than met our expectations, considering how much it costs.
Among Wireless-N routers we've reviewed this year, the DIR-615 is by far the most affordable; however, its performance is in no way the slowest. In CNET Labs' throughput test, where the router was set up to offer its best performance, the DIR-615 scored 33.2Mbps, slightly faster than the Apple Time Capsule. At this speed, the DIR-615 can finish transmitting 500MB of data in about 2 minutes.
On CNET Labs range test, the DIR-615 did slightly better by being faster than both the Time Capsule and Apple's new Airport Extreme Base Station, at 21.7Mbps.
The DIR-615 also successfully passed our mixed mode test, where it was set to work with both Wireless-N and legacy wireless clients at the same time. The router achieved 25.8Mbps, which is about 5.8Mbps faster than the Apple Time Capsule.
Overall, the DIR-615 performed well in our tests. The router could hold up a stable connection up to 230 feet away in our testing environment. It also passed our 48-hour stress test, in which the router is set to perform continuous heavy data transfer between clients, without any hiccup.
Service and support
As with all of its new routers, D-Link backs the DIR-615 with a one-year warranty, which is standard for wireless routers these days.
