Summary: You won’t find some of the latest features, such as the ability to operate a guest network or share a USB printer or storage device, and its integrated switch is limited to 100Mb/s, but the DIR-615 does offer UPnP support, D-Link’s vaunted QoS Engine, and a host of features you typically see only in high-end routers.
Pros: Cheap; fast enough to stream HD video to our media room; delivered usable bandwidth long-range.
Cons: Lacks the ability to share USB printers and storage devices; unable to operate a guest network.
Excerpt: D-Link dropped one antenna and the 100-Mbps Gigabit Ethernet feature from its flagship DIR-655 router for this budget model, but you’ll hardly notice. This router supports WPA and WPA2 encryption standards, has a parental access feature to block Internet use for kids during certain hours of the day, and has an inconspicuous black design. The CD installer worked fast and had us up and running in 5 minutes.
Pros: Great price, Fast speed, Extra features
Cons: Cant connect beyond about 300 feet, No Gigabit Ethernet ports,
