Wireshark is the world’s foremost and widely-used network protocol analyzer. It lets you see what’s happening on your network at a microscopic level and is the de facto (and often de jure) standard across many commercial and non-profit enterprises, government agencies, and educational institutions. Wireshark development thrives thanks to the volunteer contributions of networking experts around the globe and is the continuation of a project started by Gerald Combs in 1998. Wireshark® is a network protocol analyzer. It lets you capture and interactively browse the traffic running on a computer network. It has a rich and powerful feature set and is world’s most popular tool of its kind. It runs on most computing platforms including Windows, macOS, Linux, and UNIX. Network professionals, security experts, developers, and educators around the world use it regularly. It is freely available as open source, and is released under the GNU General Public License version 2.

Vistumbler is a wireless network scanner written in AutoIT for Windows . The main purpose of vistumbler is to map and visualize the access points arount you based on the wireless and gps data collected. For best results, disconnect from all access points while scanning for networks. If no access points show, make sure the right network adapter is selected in the Interface menu. GPS receivers need to be serial-based and show up as a COM port. If you have a built in sensor that uses the windows location platform you may be able to use a tool like 'Centrafuse Localizer' to create a virtual com port that vistumbler can use. 'GPSGate Splitter' also has some tools to create a compatible virtual com port that vistumbler can use.

Easily analyze your Wi-Fi and see the issues preventing you from having a stable and fast connection. You can run a comprehensive scan of your wireless network, get an interactive color-coded heatmap, and see the "dead" zones clearly. Visualization is the key for good planning — once you scan the site, Wifiner creates a visual heatmap of your space, so you can see where improvements need to be made to your network and how you can move the access points for optimal placement. Wifiner offers 11 types of heatmaps for better understanding which parameters affect your network most and comparing them to each other. Wifiner is friendly enough to those who are setting up their very first network at home and at the same time can provide incredibly detailed report to those who have a lot of experience in the field.

Opensignal speed tests measure your mobile connectivity and signal strength. Opensignal runs a 5 second download test, 5 second upload test and a ping test to provide a consistently accurate measurement of the internet speed you will likely experience. The speed test runs on common internet CDN servers. The internet speed result is calculated with the middle range of samples. Opensignal’s video test plays a 15 sec video snippet to test and log load time, buffering, and playback speed issues in real-time to show you exactly what to expect with HD and SD videos on your network. Always know where to find the best coverage and fastest speeds with Opensignal’s network coverage map. The map shows signal strength down to street level using speed test and signal data from local users. The cell tower compass allows you to see which direction the closest or strongest signal is coming from, enabling you to more accurately use broadband and signal boosting technology.

Meteor is an ad-free internet speed test tool that can be used to check the speed of your mobile connection (on 3G, 4G LTE or 5G network connection), as well as for WiFi speed testing.
