I'm trying to expand the wireless network in my church and am having some issues. I'm not a networking expert so I'd appreciate some input.
Here's our setup:
AT&T/Motorola Gateway (NVG589)
Seems to function as both modem and a router/access point, but wireless broadcasting has been turned off on this device.
Connected to a 24 port switch via Ethernet
Connected to an office router from the DSL port on the NVG589
Generates IP: 192.168.1.254ASUS router (RT-AC87U)
Serves wireless for building 1.
When wire from NVG589 is fed to Asus' WAN port, it has to create a new IP. e.g. 192.168.2.1 - now devices that are connected directly to the switch cannot be seen by devices wirelessly connected to the router. This is a problem.
If wire from NVG589 is fed to a LAN port in the router, same IP is given, all devices can be seen, but now cannot access admin GUI for router.- We have 2 other routers in another building that are having the same issue as above.
When the wire from the switch is plugged into the WAN port, I can access admin and can get online, but I can't see the devices that are hardwired to the switch or that are on the other routers.
When the wire from the switch is plugged into a LAN port, I can get online and can see all other devices successfully, but now I have no access to the router admin.
So I feel like I'm almost there but now I have no access to the router admin page/features.
What is the correct/best way to make all this work?
