inSSIDer — Defeat Slow Wi-Fi

Most of us have a love-hate relationship with our Wi-Fi network. It is awesome when it works... and frustrating when it doesn't. inSSIDer helps to remove that frustration by showing you exactly how your network is configured, how neighboring Wi-Fi networks are impacting yours, and gives suggestions for fast, secure Wi-Fi.


See your Wi-Fi environment

Since 2007 inSSIDer has been the leading tool for visualizing Wi-Fi. With inSSIDer you will instantly understand how your Wi-Fi network and the neighboring Wi-Fi networks are interacting. inSSIDer shows you the essential details about your Wi-Fi access points including channel, channel width, signal strength, Wi-Fi generation, maximum data rate, and security. It also shows you how the neighboring Wi-Fi networks are impacting your Wi-Fi.

Analyze your Wi-Fi environment

inSSIDer analyzes the configuration of your Wi-Fi including channel settings, security, signal strength, and the impact of neighboring Wi-Fi networks. Then in plain English inSSIDer shows you what's working great, what could be improved for faster Wi-Fi, and what definitely needs fixed ASAP.

Improve your Wi-Fi security and speed

After seeing your Wi-Fi and having inSSIDer analyze your Wi-Fi, you are ready to make changes to improve your Wi-Fi. The combination of inSSIDer and our library of free Wi-Fi guides and videos are the tools you need to defeat slow Wi-Fi forever!

A deeper look at inSSIDer

Quickly find access point details

The capabilities and configuration of your access points have a huge impact on whether your Wi-Fi is sloooow or fast. But this information is typically hidden for mesh systems or buried in a dozen configuration screens for standard Wi-Fi access points. With inSSIDer all of the important access point configuration details are shown in a single, easy-to-read list.

Discover which channels are busiest

Selecting a quiet channel for your Wi-Fi network will improve your Wi-Fi speed, and a channel with only a single Wi-Fi network can be much busier than a channel with multiple Wi-Fi networks. The Channels Table in inSSIDer shows you how busy each channel is, making it easy to find a channel that is relatively quiet compared to other channels.

See devices on your local network

inSSIDer not only shows your information about your Wi-Fi access points, it also scans your Local Area Network (LAN) to determine what devices are on your network. For some devices inSSIDer can even show you what type of device it is and automatically find the device name.

Learn more about Tonic

WYSIWYG Packet Capture

What you see is what you get! Select a network, access point radio, or client, and Tonic will automagically tune the connected packet capture adapters to the right channels.

Drill down to a client, and watch as Tonic keeps you informed about what it's captured. Data frames, ACKs, Authentication frames - Tonic keeps track of everything in real time. You'll never doubt that you captured an Association Request ever again.

If you see it, you've captured it!

Get Into the Flow

Source? Destination? Transmitter?! Receiver?! When all you need is a quick view of what packet went where, Packet Flow has you covered. Simple arrows show who transmitted the 802.11 frame, and colorful labels show what kind of frame it was, so you can track Wi-Fi conversations more easily than ever before.

Packet Flow makes you wonder, “Why didn’t we always do it like this?!

Layer Up!

Tonic uses Eye P.A.'s Airtime Usage technology to calculate channel congestion at the packet layer in real-time, so you can exactly who is eating up time on the channel.

But wait, there's more! Plug in a Wi-Spy DBx to unlock Spectrum Utilization (that's a measurement from the Physical Layer), so you can compare Layer 2 (Air Time Usage) and Layer 1 (Spectrum Utilization) in the same application! It doesn't matter what is causing channel usage anymore - if it's non-Wi-Fi, Tonic will see it. If it's Wi-Fi, Tonic will see it!

Note: Tonic requires one to three supported packet capture adapters. Be sure to grab at least one at checkout!
