This story has been updated. Other vendors, such as Netgear or Slingmedia also, offer multiple-port PowerLine adapters.
I remember Belkin was the first vendor who sent us a Pre-N router, the Belkin Wireless Pre-N Router way back in 2004. Ever since, it hasn't been the most prolific vendor in wireless networking in comparison with D-Link, Linksys, or Netgear.
According to Belkin's Web site, the new router will have network storage capability, similar to that of the Linksys WRT610n, where you can attach a USB external hard drive to the router and make the storage available to every computer in the network. It also has other standard features for high-end routers including: Wi-Fi Protected Setup, Draft N 2.0 compliance, Gigabite Ethernet, and so on. It's unclear whether or not the product will support dual-band, working in both 2.4Ghz and 5Ghz frequencies spontaneously. The new router is slated to cost $120.
On the other hand, it's very clear that Belkin's new line of powerline networking adapters offers some interesting features. The Powerline AV+ has three network ports (instead of one like most others I've seen) enabling you to use up to three devices with it at a time without having to get a switch. Belkin claims that the new adapter is capable of delivering throughput speed up to 200Mbps (twice that of a regular wired connection), which is more than you need to stream HD media contents.
The Powerline AV+ comes in a kit that includes one three-port adapter and one single-port adapter with a estimated price tag of $180.
