Lee’s (Wireless) Network Toolkit
Wi-Fi is an extremely nuanced area of networking, where strong opinions rage about the “best” tools. For me, wireless starts with the Ethernet network it connects to, so I’ll begin describing my toolkit by first taking you to Korey Robello’s excellent My Network Toolkit.
A collection like Korey’s is foundational for the wired side of Wi-Fi work. The only thing I might add to Korey’s setup is a basic PoE/link tester, such as Fluke Networks’ NetTool.
Beyond that, Wi-Fi support tends to be software-based, with some special dongles depending on programs in use.
Here are my must-haves:
- Spectrum analyzer, Wi-Fi SSID/channel tool. There are many to pick from, ranging from freeware to more advanced (pictured: Oscium WiPri).You usually you need a dedicated adapter for the higher-end products. The goal: demystify what’s in the air, from Wi-Fi networks to interference.
- Packet analyzer. Here, there’s no cheap way out. Wi-Fi packet capture takes a specialty adapter for Windows (pictured: MetaGeek Eye PA) or a newer Mac laptop that can natively do 802.11 packet decodes.
- Wi-Fi performance tester. Strong signals are only half the story, and you should have some sort of consistent methodology on hand to measure what the Wi-Fi can deliver at a given location and point in time. (pictured: Fluke Networks’ AirMagnet AirCheck for Android)
- Network Management System (NMS). Regardless of which WLAN vendors you support, each has a graphical interface that tells what’s going on as the system itself sees it. This is a critical complement to the other tools listed here.
Any collection of Wi-Fi tools includes one easily overlooked item: experience. The more you do Wi-Fi (with some formal training along the way), the better you’ll be at your trade.
