dot11Expert Portable

dot11Expert Portable is a seemingly simple, yet powerful application that can display information about your wireless network connections, including the authentication type, used cipher, and signal quality. This type of software is practical for troubleshooting wifi connectivity issues.

Since it's portable software, you can just extract the files from the downloaded archive and double-click the .exe to launch dot11Expert, as well as keep it stored on a thumb drive and be ready to run it on any computer to analyze wifi info, especially since it takes up little disk space.

As far as the interface is concerned, the wireless monitor keeps things clean and intuitive. All wireless connections are autodetected as soon as you reach the main window, and you can examine the name, signal quality, authentication and cipher type of each network, as well as the MAC address, SSID, channel number and frequency, along with RSSi (signal strength, expressed in decibels).

More details can be retrieved for any selected network access point, such as the link quality, beacon period, timestamp, host time stamp, capabilities, and rates. There's also a graph available, which represents the real-time signal strength.

When it comes to network adapters, you can find out a bunch of technical details, like the MAC layer status statistics (e.g. sent and received number of frames, WEP excluded count, CCMP replays and decrypt errors) and PHY layer details (e.g. failed, retry and multiple retry count).

What's more, dot11Expert Portable stores all information about network adapters, connections and access points in a log file, which can be accessed from a menu. This is highly useful for finding out the exact date and time when new network connections were identified by the app, among other details.

All things considered, dot11Expert Portable can be quite useful to those interested in troubleshooting wifi issues by reviewing software and hardware information. It had minimal impact on the computer's performance in our tests.
