The D-Link DIR-625 has been added to the Router and Wireless Charts. The DIR-625 is one step up from D-Link’s entry-level draft 802.11n DIR-615.

The 625 is also a two-antenna design (2T2R) with a four port 10/100 switch. But it has a different Ubicom processor that yields 100 Mbps wire-speed unidirectional routing throughput and 144 Mbps of total simultaneous up/downlink throughput. It also maxed out our Maximum Simultaneous Connections test at 200 connections.

I’ve covered some of the basic elements of Multicasting, such as IGMP and the Layer 2 switching components in my previous posts (Part 2). This article will go into the technology behind Multicasts at Layer 3 and some of the issues limiting wider use of Multicast technology.

As you recall in my first post, I observed that Yahoo’s transmissions of live NHL games would seem to be good candidates for Multicast, yet were being sent as unicast. Then I covered the simple issue of enabling Multicast within a local area network. Coming full circle, here we are diving into Multicast technology to understand why it isn’t more widespread.

Contest #16 has ended. The winner of the Belkin F5D5141-8 8 Port Gigabit Switch is Eli Rice with the correct answer of Vitesse VSC7388. Note that due to an article error, an answer of Vitesse VSC7338 was also acceptable. Congratulations, Eli!

I don’t seem to have any luck getting Wi-Fi Protected Setup (WPS) to work in any of the products I’ve tested that allegedly support it. And since the Wi-Fi Alliance seems to have me on its "Do Not Talk To" list, I’m turning to our readers, who tend to be a pretty knowledgeable bunch, for wisdom.
