I do have a light that flashes on my router that shows activity in "WLAN"
I probably won't be able to locate such a program for windows, but I wanted to have a user interface (in windows), that shows if someone is trying to log in or access my router from outside my house, and hopefully tell me where the incoming signal is originating from.
I don't know how easy this would be to do in Windoze (relatively easy to script it in Linux, I'd expect) AND I don't know much about the Linksys user interface (I'm assuming that it has a browser interface for configuration)... So that's my disclaimer.
You could try opening the router in your browser, finding the page that indicates connected devices, and copying that URL. Then, write a script to open that page directly by slightly editing the copied URL to include the login name and password like: http://login:firstname.lastname@example.org...vices_page.html
. The script would open this page, parse it to extract the connected devices, and issue some type of warning if/when something new connects.
There. Super simple.
