Network problem?
add a second NIC to each terminal that you want to switch over to broadband.





go ahead and plug in an ethernet cable from the pc's to the broadband router or switch.





Go into network properties for each new NIC on the pc's you added them into and set the card to receive an IP either through DHCP or static...however you have it set up..I don't know..





then just disable the nic's on each pc...then when you want to switch from V SAT to broadband just disable the VSAT NIC and enable the broad band NIC in network properties options and you should be able fine.
Reply:You can put a router in and connect all the pc's to it. If you need to switch over, reprogram the routers address.
