Have you tried to repeat the "Discovery scan" without the Internet hooked up? Perhaps this will show if the internet is being used or not.I was wondering the same thing this morning. I did a conventional discovery scan on my HP and downloaded it into Sentinel. There is an option during discovery to match the discovered frequency to the dB. Several of my frequencies did match the dB but it's not obvious where in the dB they match, it just has a flag of Yes or No. I was looking for a search kind of function but nothing. I'm thinking I'll have to search the RR dB online for that frequency to figure out what it's description is in the dB.
