I created a network from hostel wi-fi using the router pin number. Creating a private network is not allowed in my hostel. I have to remove the network, using the manage wireless networks option I can delete the wifi network from my laptop but it appears in other laptops. What should I do?
Other than deleting the WiFi network from all computers manually, there's no way to do so.
The network details are stored in an XML file on each computer and there's no way to do a "broadcast delete" of the files. Unless you write a script which goes connects to each computer & then deletes the files - which makes it sound more like a malicious file.
