You're running out of ports for your network and you need to resort to a switch. Maybe it's a better idea to get one that also supports power-line networking. Like most computer devices, a switch will need to be plugged into the wall to work, after all.
If you find yourself with that thought, D-Link's new
This is a compact four-port Gigabit switch just like any other switch that allows you to add three Ethernet-ready devices to your existing network using network cables. However, it's also the first we've seen that incorporates support for Powerline AV 500, meaning its power cable is also a data cable of a power-line network.
Basically, the DHP-540 turns the house's electrical wiring into a data cable for the same computer network it's connected to. Now you just need to plug other power-line adapters into different power sockets, such as the
In case you already have a power-line adapter connected to your router, the DHP-540 works the other way as the other end of a power-line connection, too. In this case, just plug it into a power socket at the far end and you can extend the network to up to four computers there.
The best thing about the DHP-540 is the performance. Similar to the new Powerline AV 500 adapters we've seen, it offered stellar power-line transfer speed--much faster than that of regular Ethernet connections. On top of that, it also works quite well as a regular Gigabit router for those who don't want to fiddle with power-line networking.
At a price of around $95, the DHP-540 is actually cheaper than many other regular four-port Gigabit switches. To find out if there are any catches, check out CNET's full review of the
