I have a strange problem from past few days. I use an HP laptop with Intel Pro Wireless 3945ABG network adapter. I also use VPN connection (VyprVPN) over the internet. The moment I install and run any network monitor like BWMeter, Networx or DUMeter, the wireless connection disconnects from the internet and is left only with limited connectivity. It does not matter which utility is used, the problem is same. And as soon as I quit the utility and close the bandwidth monitor application, the internet connectivity returns. I ensured in Norton 360 v3 that all my network connections are trusted and that firewall does not block any of these. Any ideas on why this could be happening and how to resolve the same will be appreciated.
