DTNT vs iwScanner

DTNT is a Windows desktop app for Wi-Fi visibility, device discovery, speed testing, saved profile review and network diagnostics. The free app surveys nearby radios and shows the current SSID, band, channel, security and live channel context. Its IP Scanner can scan the active range, remember and label hosts, filter results and copy IP addresses; users can also run speed tests with saved history, review profiles and ping once. Pro adds best-channel guidance, richer lane-pressure detail, selected-host follow-up and TCP checks. It can export speed history and profile or network evidence as JSON or CSV, and adds saved-key reveal, continuous ping and trace route. Pro costs $59, paid once as a one-time purchase. One purchase covers one purchaser or internal technician seat and can be activated on up to three Windows devices under that purchaser’s control. Network inventories, saved Wi-Fi keys, device passwords, exports and diagnostic logs are not automatically uploaded. Pro activation and startup update checks make online requests.

iwScanner is a free Linux wireless scanner with a graphical interface. It detects wireless networks and displays each access point, MAC address, channel, and encryption type. A signal chart shows the strength of detected networks, and scanning speed can be adjusted. The program uses wireless-tools and is ready to run when iwlist is available. It is designed in Glade and written in Python; the maker says PyGTK is needed in a Linux environment. iwScanner can open and save NetDetect (.ndd) and NetStumbler (.ns1) files, and the source is included with the download. The latest listed release is version 0.2.4, dated 2010-04-15, offered as an Ubuntu deb package and a generic Linux tarball. That release fixes networks being incorrectly detected as WPA2. Notes for version 0.2.3 add support for the rt2860sta card. The maker identifies Renzo Bertuzzi as author and invites email contact.
