3 routers (TomatoUSB) - Set up wireless access points and NAS?

I have 3 routers (Linksys E4200, E3000, E3000) running TomatoUSB on all. What are my options and how can I set them up for wireless access points (same SSID) while maintaining NAS access to all? For now I have the following, and able to have wireless and wired internet access on all.

Router A:
- 192.168.1.1 (admin)
- WAN connects to cable modem
- LAN 1 connects to NAS
- LAN 2 connects to Router B (LAN 1 port)
- LAN 3 connects to Router C (LAN 1 port)
- DHCP enabled (192.168.1.2-254)
- Subnet Mask: 255.255.255.0

Router B:
- 192.168.2.1 (admin)
- DHCP enabled (192.168.2.2-254)
- Subnet Mask: 255.255.255.0

Router C:
- 192.168.3.1 (admin)
- DHCP enabled (192.168.3.2-254)
- Subnet Mask: 255.255.255.0

What are my options? Thanks!

 

DHCP should be disabled on access points. Only the actual router should have it enabled.
Other than that everything seems to look fine - IPs for APs are outside the DHCP range and Ethernet cables are connected to LAN ports of Access Points rather than to WAN ports.

 

Thanks! I read DHCP should be disabled on the access points from various sources as well--will give that a try. I will try giving Router B and C 192.168.1.2 and 192.168.1.3 respectively for the admin IP.
What about "gateway" vs. "router" modes for the routers?

 

I think IPs assigned to those two APs were OK. As for the router/gateway setting I don't understand how either would be correct here - since neither is really true, but since it's definitely not a gateway, you should set it to router mode.

 

The initial IP for AP are fine, if you want to change to (192.168.1.2/ 192.168.1.3) then you should move the dhcp range a bit, but nowadays, things are smart enough that they shouldnt matter.

Actually, depends on the manf, admin IP maybe not be the ip you can access them when connected as AP. The router may assign a random IP for the AP. Best is to refer back to manual.

 

Thanks for the replies. After 3 hours of fiddling around, I figured it out. I realized there are two ways you can configure this called "cascading", and each have their own purpose (LAN-LAN is recommended since everything can find each other):

• Cascading router to another router (LAN-LAN)
• Cascading router to another router (LAN-WAN)

For those looking to set up or connect multiple routers, this is for you. Basically have your routers set up like this:

• Router A (main)
  • Internet cable to WAN port
  • LAN 1, 2, 3, or 4 ports can connect to any router's LAN port
  • WAN/Internet DHCP enabled with defaults
    
  • LAN IP address: 192.168.1.1 (DHCP enabled)
  • IP range: 192.168.1.2 - 192.168.1.254 (first/last)
  • Routing mode: Gateway
• Router B
  • LAN 1, 2, 3, or 4 ports can connect to any router's LAN port
  • WAN/Internet DHCP enabled with defaults
  • LAN IP address: 192.168.1.2 (DHCP disabled)
  • Routing mode: Gateway (yup, no need to change to Router mode)
• Router C
  • LAN 1, 2, 3, or 4 ports can connect to any router's LAN port
    
  • WAN/Internet DHCP enabled with defaults
    
  • LAN IP address: 192.168.1.3 (DHCP disabled)
  • Routing mode: Gateway
• Router D
  • etc.

With this setup, your routers have access to all routers, printers, computers, etc. connected in the network. You even have access to wireless access points on any router with wireless too. Hope this helps someone.
