Do you have a wireless networks Do you want to monitor or track the communication over your wireless networks Here just has a powerful and easy to use utility for you, that is Network Stumbler, the packet sniffer for wireless networks, which was published by WebSite. With Network Stumbler, we can monitor or track the packet over our wireless networks real time.

Network Stumbler is a packet sniffer for wireless networks. It supports wireless network cards that use the Hermes chipset, including Lucent, Dell True Mobile, Compaq WL 110, Elsa Airlancer and several others. With Network Stumbler we can: Verify that our network is set up the way we intended. Find locations with poor coverage in our WLAN. Detect other networks that might be causing interference with our network. Detect unauthorized "rogue" access points in our workplace. Help aim directional antennas for long-haul WLAN links. Use it recreationally for WarDriving.

The requirements for NetStumbler are somewhat complex and depend on hardware, firmware versions, driver versions and operating system. The best way to see if it works on your system is to try it. The following are rules of thumb that we can follow in case we cannot reach the web site for some reason. For example: This version of NetStumbler requires Windows 2000, Windows XP, or better. The Proxim models 8410-WD and 8420-WD are known to work. The 8410-WD has also been sold as the Dell TrueMobile 1150, Compaq WL110, Avaya Wireless 802.11b PC Card, and others. Most cards based on the Intersil Prism/Prism2 chip set also work. Most 802.11b, 802.11a and 802.11g wireless LAN adapters should work on Windows XP. Some may work on Windows 2000 too. Many of them report inaccurate Signal strength, and if using the "NDIS 5.1" card access method then Noise level will not be reported. This includes cards based on Atheros, Atmel, Broadcom, Cisco and Centrino chip sets. Firmware requirements: If we have an old WaveLAN/IEEE card then please note that the WaveLAN firmware (version 4.X and below) does not work with NetStumbler. If our card has this version, we are advised to upgrade to the latest version available from Proxim's web site. This will also ensure compatibility with the 802.11b standard. Other requirements and compatibility issues: Our card must be configured in such a way that it can be seen by the management software that came with the card. The Microsoft-provided Orinoco drivers that come with Windows 2000 do not work with NetStumbler. Please visit Windows Update or www.proxim.com and upgrade to the latest drivers. When NetStumbler is in "auto reconfigure" mode (the default), it will occasionally disconnect us from our network. This enables it to perform its scans accurately, and is not a bug. If we have the WLAN card configured to connect to a specific SSID, NetStumbler may not report any accees points other than those that have that SSID. Configure your card with a blank SSID or, if a blank one is not permitted, "ANY" (without quotes).

The main functions and features of Network Stumbler include: Support for Atheros, Atmel, Intersil Prism based wireless cards. Improved support for Cisco cards. Allow use of Serial Earthmate GPS (USB Earthmate should already work using NMEA and serial driver). If we scroll all the way to the right of the graph view, it will auto-scroll new data. If "Reconfigure" is on, the Windows XP Wireless Zero Configuration service will be stopped when we start scanning. It is restarted when the application exits. If we connect to a network that supports DHCP, the IP subnet is reported. If the access point is discovered in the ARP table, its IP address is reported. While we are scanning, the system will be prevented from going into standby unless power is critically low. Large files load several times faster than before (though the really large ones still don't load fast enough). A whole lot of new scripting features. Allow configuration of baud rate and other settings for GPS. Supports "Default SSID" filter to tree view. Close connection to NIC when scanning is not happening. Support for user-provided scripts to be invoked when various events occur. Use NDIS 5.1 native 802.11 features for scanning on Cisco and some Prism cards on Windows XP. Support for 802.11a on Windows XP. Support for USB devices on 98/Me. Popup menu allows deletion of APs from list. Complete rewrite of NIC access code in preparation for multiple chipset support and so on. In addition, Network Stumbler is free for us and it does not contain any adware or spyware, so we can use it safely and undisturbedly. It is a standalone software and does not need any extra software and hardware requirement. It works with most recent variants of Windows and its current version is 0.4.

Network stumbler is a wifi scanner and monitor tool for windows, it allows you to detect WLANs using 802.11a, 802.11b and 802.11g wireless cards.
Its targeted to network experts however is widely used by networking enthusiasts and hackers because it helps you find non broadcasting wireless networks.
Among it uses are:
1.- Verify that our network is well configured.
2.- Study the signal strength or coverage on different points of our network.
3.- Detect interference between one or more wireless networks.
4.- Its really useful to point directional antennas for long distance links or just put the wireless card and antenna in the best signal point.
5.- Can be used to detect non authorized connections.
6.- Wardriving, which means detect all routers near to your network.
It offers same of the functions mentioned above for GPS networks, obviously using the correct antennas, however isnt commonly used to achieve this.
Unfortunately it doesnt support all wireless cards and Windows Vista isnt officially supported, thought some people reports that it works fine, I didnt have the same luck and it didnt work on my laptop.

The license of this software is Freeware, you can free download and free use this wireless communication software.
