I am working in an institute where the internet connection is divided amongst 3 different floors: Ground Floor, First Floor and Second Floor. Now since I am new to the networking, I know the essentials.
There are two different internet connections of same company BSNL. So we call them as BSNL-A & BSNL-B.
Now here, LET ME TELL ONE THING. THERE IS NO SINGLE ROUTER IN CAMPUS. THE MODEMS (not routers) of two connections respectively BSNL-A & BSNL-B are connected directly to the switch and there onwards the connection is distributed amongst various computer terminals.
BSNL-A has gateway 192.168.1.1 & BSNL-B has gateway 192.168.100.1
Now the main issue is, when we turn ON both the switches & both the modems BSNL-A & BSNL-B modems, the internet connection work with ip assigned by one of BSNL-A & BSNL-B modems uptil some time. But later this creates conflict and the shared folders doesn't get accessed and there is yellow exclaimation mark on network adapter symbol. Both the connections BSNL-A & BSNL-B are active.
What is the solution to this? I want to keep both the ISP modems active and connected to the switch all the time and also want to keep the folder sharing unaffected despite the ip assignment gets changed automatically. All the IPs currently are assigned automatically.
Please guide me about the solution on this.
