D-Link DHP-501AV PowerLine AV 500 Adapter Starter Kit review: D-Link DHP-501AV PowerLine AV 500 Adapter Starter Kit

The D-Link PowerLine AV 500 Adapter Starter Kit excelled in our testing, averaging 141Mbps, about 50 percent faster than a typical Ethernet connection. Note that this is sustained real-world throughput speed, after all hardware and software overheads. While it's not the fastest, about 20Mbps slower than the Netgear XAV5501, it's still by far one of the fastest power-line adapters we've seen. The TrendNet TPL-401E2K, for example, which is another Powerline AV 500-based adapter, scored just 79.2Mbps.

Judging from the Netgear XAV5501 and now the D-Link DHP-500AV, we believe that power-line networking is no longer to be taken lightly in terms of speed. It now makes more sense to use it instead of traditional Ethernet connections, which require running network cables all over the place. Compared with Gigabit Ethernet, however, the Powerline AV 500 standard is still significantly far behind. But for most home and even small-office networking needs, these power-line connection speeds are more than fast enough.

Be aware that, similarly to wireless networking, power-line networking performance varies based on the environment. This means depending on the condition of your home's electrical wiring you could get different results from our numbers. Based on our experience with it, though, we believe that the D-Link DHP-501AV kit would perform well in most situations.

The four-star D-Link Powerline AV 500 Adapter Starter Kit DHP-501AV would be an Editors' Choice if it offered a pass-through socket. Nonetheless it's one of the best power-line adapter kits on the market for homes or small offices.
