We have 16 computers connected in Internet in P2P network via a hub. We acquired this internet connection by subscribing from a commercial provider. Just recently our company has provided us the corporate Intraweb by means of IP radio. We don't want to mix this up for security reason so we bought another hub for intraweb using the same cable thinking that by just moving the connector to intraweb hub and changing the IP Adresses we can toggle to the intraweb and internet. My problem is whenever I change the connector to the Intraweb hub my LAN connection become unplug. Is there anybody provide me help?
