    Remote Authentication Dial-In User Service (RADIUS) servers are common in enterprise networks to offer centralized authentication, authorization and accounting (AAA) for access control.

    Review: Sprint Overdrive 3G/4G Mobile Hotspot

    Posted May 5, 2010 - 3:01 pm

    If you're like me, you need to be connected to the Internet constantly, on multiple devices, and at the highest speeds possible. Wi-Fi is great for connecting from places like home, work, and local coffee spots. But when I'm on the road, finding usable Wi-Fi hotspots for connecting my wireless devices is a challenge, and I often use (or wish I could use) cellular data service instead.

If multiple Wi-Fi clients claim a share, performance can rapidly--and, in the case of streaming video, visibly--deteriorate. For these reasons, our look at networking products has two components.

    Posted December 31, 2008 - 12:08 pm

    While not as well known or widely used as Wi-Fi or Ethernet, powerline networking—using your existing home electrical wiring to transmit data, turning every outlet in your house into a potential network connection—can be a lifesaver when Wi-Fi won’t reach or when you can’t (or won’t) run Ethernet cabling.
