Exceeded my data limit for last four months, how to stop that. Data leak somewhere?


As the OP, I just had the disconcerting experience of trying to log in to my ASUS Mesh Router, and merde alors!, I forgot the dang password. So I have to do a reset. If I change the password, then I have to update 1 desktop, 3 (or more) laptops. 2 iPhones, 2 iPads. the home security camera, and probably other stuff And of course, any decent password has to be long and a random mixture of characters.

Yes, I'm hosed, whatever I do.

You can export the WiFi connection information from any of your Windows computers. Open a command prompt, and enter:

Code:
 netsh wlan export profile key=clear folder="%USERPROFILE%\Desktop"

That will save each WiFi connection's information to a separate XML file on your desktop.

Code:
Interface profile "Banana" is saved in file "C:\Users\LadyGodiva\Desktop\Wi-Fi-Banana.xml" successfully.

Interface profile "Mango" is saved in file "C:\Users\LadyGodiva\Desktop\Wi-Fi-Mango.xml" successfully.

Each file will have the WiFi password in it. After you reset your router, you can set the WiFi password back to this value, and your other devices will keep connecting just fine.

XML:
            <sharedKey>
                <keyType>passPhrase</keyType>
                <protected>false</protected>
                <keyMaterial>mine's redacted</keyMaterial>
            </sharedKey>


Using Nir Sofer's program over a 24 hour period, I didn't see anything odd. But I want to put this problem to bed, and if it means ensuring the pain of updating all these devices, I don't have a choice, do I?

If you're using an ASUS router, you can turn on Traffic Analyzer to see which clients are using the most bandwidth.
