Free tool to scan WiFi network in your area, and find odd ones

June 17th, 2020 No comments

Once when I was teaching at an Engineering College, scanned Wi Fi on my laptop to show students about its range and signal strength. I got an odd AP at the bottom. Wished long to identify the funny AP at the bottom.

Here is the solution. WifiInfoView scans the wireless networks in your area and displays extensive information about them, including: Network Name (SSID), MAC Address, PHY Type (802.11g or 802.11n), RSSI, Signal Quality, Frequency, Channel Number, Maximum Speed, Company Name, Router Model and Router Name (Only for routers that provides this information), and more…

If any of you have a distant dream of learning Programming, Data structures and Algorithms from the experts at IITs, here comes an excellent opportunity.

Online course: Free for all, Certification exam: For a nominal fee

“This is a course on programming, data structures and algorithms. The learner is assumed to have no prior experience of programming, but is expected to be at the level of a second year undergraduate college student in science or engineering. The course will run over ten weeks with about 2-3 hours of lectures per week.

At the end of each week, the learner is expected to write some programs and submit them for grading. These programming problems are classified as easy, moderate or difficult. The easy problems, typically, are repeats from the lecture. The moderate and difficult ones will require increasing levels of initiative from the learner. 
In addition, at the end of each week the learner is expected to answer a set of objective-type assessment questions. “ source: https://onlinecourses.nptel.ac.in/explorer
