It’s a big breakthrough in wireless connectivity, but don’t let MU-MIMO’s limitations catch you off guard. Here are 11 ways to get up to speed on MU-MIMO Wi-Fi.

Attempting to "hack" into your own wireless network can help you spot potential Wi-Fi security vulnerabilities and figure out ways to protect against them.

Wi-Fi can be fickle. The RF signals and wireless devices don’t always do what’s expected – it’s as if they have their own minds at times. Wireless site survey tools can help avoid Wi-Fi interference issues and WLAN configuration problems.

Tips about Wi-Fi security because wireless is inherently less secure.

A review of five mobile survey apps - iBwave Wi-Fi Mobile, iMapper WiFi Pro, WiFi Analyzer and Surveyor from ManageEngine, Wi-Fi Visualizer from ITO Akihiro, and WiTuners Mobile - for enterprises to small offices.

While many (but not all) users are familiar with the concept of security software, there are more basic ways to protect unwary surfers from phishing sites, botnets, intrusive advertising and other unwanted visitors: DNS services.

Though you may know and follow basic security measures on your own when installing and managing your network and websites, you'll never be able to keep up with and catch all the vulnerabilities by yourself.

We sometimes focus more on the wireless side of the network when it comes to security because Wi-Fi has no physical fences. After all, a war-driver can detect your SSID and launch an attack while sitting out in the parking lot.

There are endless software tools and utilities out there to help you in managing your network. Here are some of the best free ones. They can help you with deploying, maintaining, troubleshooting, and upgrading Window Servers, your domain, and aid with other miscellaneous network tasks.

All five tested products validate the superior throughput of 802.11ac

Whether you’re in IT or an average end user, here’s what you need to know about the changes and new features.

Earlier this year we tested several consumer-level 802.11ac routers. Here, we take a look at two enterprise-level access points. They're a part of the so-called "Wave 1" phase of the 802.11ac standard: both access points support up to three spatial streams and 80 MHz wide channels, offering theoretical data rates up to 1.3Gbps. But just as we saw with the 802.11ac routers, you won't get throughput rates nearly that fast.

Offering Wi-Fi can be a good way to increase return customers and boost revenue in retail stores, hotels, cafes, etc. And it provides convenience for contractors and associates working in corporate offices and conference rooms. Though visitors might have 4G mobile devices or laptops, Wi-Fi can provide a faster, higher quality connection.

Ekahau offers most comprehensive set of Wi-Fi site survey features in three-product test

In the early days of Wi-Fi, site surveys were fairly basic and involved running around with a laptop looking at simple signal levels. The next step was mapped-based tools that provided a good visual of Wi-Fi coverage, but still involved carrying a bulky laptop around.
