D-Link DI-624M Super G with MIMO wireless router review

The default setting for the DI-624M Super G with MIMO wireless router is Super G with Dynamic Turbo. In the setup process, D-Link does not explain the four settings, which also include Super G with Static Turbo, Super G without Turbo, and Disabled. Static Turbo is not backward compatible with legacy non-MIMO devices, whereas Dynamic Turbo should be. When installed on our own notebook, however, the setting worked, but the range was less than that of our standard G router. D-Link tech support recommended that we change the setting to Super G with Static Turbo, a move that yielded worse performance, with the signal dropping about 20 feet from the router. The router setup utility then hung, and we had to reboot our desktop PC.

In our CNET Labs tests, the D-Link combo topped the other MIMO duos, with its 51.5Mbps score on our maximum-throughput test. The pair achieved a respectable throughput of 33.3Mbps at a distance of 200 feet but scored a lackluster 17Mbps in mixed mode. When we installed the router and the PC Card in a home setting, however, the signal dropped off at a distance of 70 feet, delivering worse throughput than our standard 802.11g router.
