I am no network admin. But I am the in-house IT guy for a small firm with, what appears to be, a fairly complex office network.
The network has two routers, the first goes into the network through a firewall and then goes from the firewall to one large switch. The second router is attached directly to the switch. My suspicion is that the first handles all inbound connections and the second handles only outbound. Both have their own lines. Until recently we had been using the second router to connect wireless devices to the network, but that has recently stopped working (wirelessly connecting that is) and I am trying to figure out roughly what has happened.
I can check the inbound router's settings through it's default ip address from anywhere on the network, but I can't seem to connect to the other router at all. If I plug a laptop directly to it, the laptop connects to the network through it, but I still can't view it's settings because not only do I have no idea what IP address to connect through, but it doesn't seem to show up on ipconfig or netstat.
Q1: Why might we have two routers?
Q2: Why might the wireless connection not be working?
Extra (possibly irrelevant) details;
- We have two servers connected to the network hosting DHCP, Print Management, SQL, IIS, DNS, Directory, and more
- One server, which handles the email exchange, is running windows server 2003. The other which handles almost everything else is running windows server 2012.
- The two routers each have their own line. They are standard BT Business Hub 3 routers.
