Troubleshoot WiFi with Chanalyzer

We probably don't need to tell you that interference is a problem for WiFi, but how do you know if you've got it? Chanalyzer by MetaGeek is WiFi troubleshooting and spectrum analysis software designed for IT professionals who deploy and maintain wireless networks. Honestly, who doesn't have wireless nowadays? We turn RF spectrum data into highly interactive charts and graphs, allowing you to truly visualize your wireless landscape. Chanalyzer creates a complete picture of how both 802.11 WiFi and non-WiFi transmitters impact your wireless networks, giving you the information you need to resolve any issues affecting your users.

See the Invisible with Wi-Spy

Wi-Spy is a custom USB spectrum analyzer designed specifically for troubleshooting WiFi issues. Unlike most WiFi tools, Wi-Spy is able to measure everything going on in your air. If you can't see your air, you can't own your air. With Wi-Spy DBx, you can measure RF signals in the 5 GHz band, which is quickly becoming as crowded as the 2.4 GHz band!

View Activity in the Spectrum Over Time

Not all interference is constant. Maybe that microwave at lunch time shuts down half your office. How could you visualize that?

Chanalyzer takes a unique and powerful approach to recording playback with Waterfall Navigation. The Navigation Waterfall shows you the entire recording from start to finish, so you can identify events, and zero in on them quickly. Rewind, fast forward, or even pause while Wi-Spy records in the background. It's like a DVR, but for spectrum analysis. Just skip to the "good" stuff.

Identify Non-WiFi Interference

With Chanalyzer's built-in library of signatures, you can identify devices that are interfering with your wireless network. Signatures follow your mouse to the density view, so you can make a direct comparison. Find a new signature that we haven't cataloged yet? Add it to your own customized signature library.

Add your own pictures, create your own descriptions, or just use the defaults. After you’re done, export to PDF and present it to your client or boss.

Track Down Interferers with Device Finder

Man, spectrum in 2.4 GHz is packed. Tracking down any pesky devices that live there has never been easy. Now it is.

The Device Finder 2.4 GHz Directional Antenna is a hardware accessory for Wi-Spy that increases the receive sensitivity in a single dimension. The stock antenna included with Wi-Spy is omni-directional; Device Finder is a highly directional one. You can point it in any given direction to quickly track down troublesome interferers.

Locate Non-WiFi Interferers

Ever play "Hot and Cold" as a kid? You know, where you get "warmer" the closer you are to what you're looking for? Device Finder is "Hot and Cold" on steroids.

With Device Finder, you can track down devices that are interfering with your wireless network, like cordless phones, wireless video cameras, and other analog devices. Increase speed and accuracy with the Device Finder directional antenna, which can lead you right to the interfering device. The Device Finder view shows a signal strength over time graph similar to the Networks Graph, but also shows the signal strength of a selected frequency range. Device Finder will enable you to actively seek out transmitters so you can know exactly what is happening around your network. You're getting warmer... WARMER...
