inSSIDer 2

The only free tool of its kind...

Wi - Fi network scanners have been around for some time. InSSIDer is a free software designed to work with Windows. The software is advanced enough to run on 64 bit Windows which is a very positive part of this software’s functionality. Most other wireless scanners don’t work well with Windows Vista and Windows 7 and cannot show more than one channel or SSID at a time. By showing all of your SSIDs, you can get a great view of your wireless network as you walk around and perform a wireless survey.

With inSSIDer, anyone can see all of the channels, SSIDs and signal strengths. The software separates wireless signals with colors. This software is truly developed for the current generation wireless geeks

InSSIDer uses native Wi-Fi API creating a program that recognizes a majority of wireless cards that are available.

One of the best features is the ability to group these wireless signals by MAC Address, SSID, Channels, and RSSI.

The inSSIDer project was inspired by Charles Putney's Wi-Fi scanner. Norman Rasmussen modified the project to use the the ManagedWifi C# wrapper for the Windows Native WLAN API.

The ManagedWifi Library is licensed under the Lesser GNU Public License, Version 2.1. Source for this library, as modified for use in inSSIDer, is included in the public repository described above.

Many thanks to Charles and Norman, as well as the ManagedWifi team for getting this project off the ground.

Tyler Adkisson, Joel Carpenter, Philip Smith and Jeff Goff submitted changes to the latest edition of inSSIDer! These changes include GPS support and Netstumbler output.

 
Reviews

inSSIDer scans networks within reach of your computer's Wi-Fi antenna, tracks signal strength over time, and determines their security settings (including whether or not they're password-protected). Previously mentioned NetStumbler has long been a favorite for this sort of functionality, but it doesn't work well with Vista or 64-bit XP. inSSIDer, on the other hand, works like a charm on both Vista and XP, and it's open-source to boot. - LifeHacker

"I really like inSSIDer, which is open source and available to download from MetaGeek. It's a simple tool that graphically displays all the networks visible in your area, along with their relative signal strength.

It also records signal strength over a five-minute period, which is particularly useful in an office environment as laptops pop on and off the network, and intelligent access points adjust their transmission power to match.

I've fired up a copy of inSSIDer in several different home and SME environments where the owners were complaining of poor wireless speeds and frequent drops, only to find their wireless router working on exactly the same channel as several of their neighbours, and so all of them were competing for a time-slice of the same frequency.

It's so easy to spot these kinds of problems with a tool such as this, and with a quick change of channel the wireless network suddenly starts working properly again." - PC Pro

Unsuck Your Wi-Fi

Sure, our FREE inSSIDer Wi-Fi scanner software can show you information about Wi-Fi traffic, but it's blind to any physical RF issues. And it's those bad-boys that are causing a large percentage of wireless networking problems. Without a robust Wi-Fi tool to examine the physical RF layer, you will only know WHEN things go bad, but never WHY.

That's why MetaGeek developed it's line of Wi-Spy products. These full-featured and award-winning portable spectrum analyzers display all RF activity around you, picking-up wireless networks, microwaves, cordless phones, and anything else that could potentially interfere with your network.

Wi-Spy spectrum analyzers make troubleshooting wireless simple and effective. So while you're here poaching our FREE inSSIDer software, why don't you check out our complete line-up of Wi-Spy tools. We've developed one to cover every possible level of network geek.
