can you recommend any (opensource or trusted) android apps to check who’s using your wifi? or any cmd prompt code to search on the desktop?
a small doubt: can anyone hack your computer through WiFi? If so, How to prevent that (or) How to take measures after you think you been hacked?
WiFi is really no less secure than wired aside from being harder to keep people from having physical access, and since most home users don’t use any kind of connectivity protection on wired ports it might even be seen as more secure.
