Belkin N750 DB Wireless Dual-Band N+ Router review: Belkin N750 DB Wireless Dual-Band N+ Router

The N750 DB offers a few other standard advanced features such as such as Access Control, which can restrict the Internet access of certain computers in the network; Virtual Server, which enables a computer to be set up for a particular service, such as an FTP or HTTP server; and Quality of Service.

The router's Web interface is typical of Belkin routers, organized and responsive. Unfortunately, it seems the router's current firmware doesn't support IPv6, the new version of Internet Protocol intended to replace the current IPv4, which is running out of addresses. This won't affect most home users, however, and might be added via a firmware update. What will almost certainly affect many users is the fact that the router doesn't support the old WEP wireless encryption method, just WPA and WPA2. While WEP is not as secure as later methods, it's used by older wireless clients and without this support the router will not work with a large selection of existing wireless devices.

The router also supports Wi-Fi Protected Setup (WPS) with a button on its front that initiates a 2-minute time window in which other WPS-enabled devices can enter the wireless network automatically.

Performance
The N750 DB showed mixed performance in our testing.

On one hand, the router's throughput on the 5GHz band was very fast over a short distance (15 feet), at 92.34Mbps. Even when we increased the distance to 100 feet, the router still registered 74.64Mbps. At these speeds the router can finish transferring 500MB in significantly less than a minute. And in both tests, the router was the third fastest on our comparative charts. Note that this formal testing was done with 300Mbps Wireless-N clients. When we tried the router with clients that support the new 450Mbps, the Belkin's performance on the 5GHz band proved to be even faster, up to a 50 percent improvement. As our 450Mbps testing plan hasn't been formalized, for now, we'll keep using the numbers generated by 300Mbps Wireless-N clients for the charts. Note that most Wireless-N clients currently on the market only support the 300Mbps standard or slower.

On the other hand, the router's performance on the 2.4GHz band, though quite fast, was consistently below average in our testing. Its 2.4GHz range was very good, stretching to about 290 feet away. Its range on the 5GHz band was much more modest, just about 200 feet or so. For both bands, we found that the router was best used within 150 feet or less.

The router passed our 24-hour stress test. For this test, we set it to transfer a large amount of data back and forth between clients on both bands, and it didn't disconnect once.

Like the Play Max and many other routers with USB ports, the performance of the N750 DB's network storage feature was slow, averaging 21.9Mbps and 55.5Mbps for writing and reading respectively via Gigabit Ethernet. At these speeds, the router can't offer much from its connected USB external hard drive, other than some light file sharing or music streaming.

Service and support
Belkin backs the N750 DB Wireless Dual-Band N+ with a two-year warranty, which is good for a router, as routers usually only come with a one-year warranty. Belkin's toll-free phone support is available 24-7, or you can fill out a form at Belkin's Web site for e-mail support. Its Web site also offers documentation, downloadable drivers, and FAQs.

Conclusions
We loved the N750 DB Wireless Dual-Band N+'s price and 5GHz throughput but were let down by the performance of its 2.4GHz band and its lack of compatibility and features. Still, it would make a good, affordable high-end router for homes that don't have legacy wireless clients.
