Ok I have 2 routers and one modem. (I also have a switch handy) I would like to connect both routers to the modem. The only catch is I don't want both networks down if one router stops working or is having maintenance on it.

my current set up is like this: 1 modem, 2 routers, 2 different networks

But if router 1 goes offline or down nothing on router 2 will get internet. I only have access to router 2's settings and can't see what is going on with router 1 when it stops working. My tech level is low in networking but mid-high on troubleshooting.

my switch is a Linksys SE2500, while router one is an Apple AirPort Extreme Base Station, and router two is Linksys EA4500

If anyone can provide me a link or a method of making 2 routers use the same IP address from one internet connection

  • Does the modem have an IP address or is it bridged to one of the routers? – Paul Jul 8 '14 at 0:32
  • What is the make and model of the modem? – David Schwartz Jul 8 '14 at 1:31
  • ok the modem provides a dhcp and is a motorola – marshe Jul 8 '14 at 1:40
  • As for the physical connectivity, connect a switch to the LAN port of the modem. Then connect each router to the switch. As for Layer 3 you're going to have to figure out how to get both routers connected to the internet via the modem, assuming you're getting a single ip address from your ISP. – joeqwerty Jul 8 '14 at 1:51
  • yes only one ip address from ISP – marshe Jul 8 '14 at 1:57

This should "just work". Connect both routers WAN ports to the switch. Connect the modem's LAN port to the switch.

  • do you think I'll need to contact my ISP about the dhcp or connection set up from what it currently is. For if I have to set something up on each router – marshe Jul 8 '14 at 2:26
  • No, I don't. Why would you? All devices should work in their default configurations because they're all doing exactly what they've been designed to do. The modem is giving a few devices (the routers) Internet access, as it's designed to do. The routers are giving a few devices (their LANs) Internet access, but not giving Internet-side devices access to their LAN, as they're designed to do. – David Schwartz Jul 8 '14 at 2:43
  • I'll get back to you on the results in a couple days when I have the time. (gotta love smartphones on trains) – marshe Jul 8 '14 at 2:51
  • alright this did not work called ISP and they are claiming I will need a second IP address from them for an additional fee – marshe Jul 9 '14 at 22:44
  • This only 'just works' if the modem has a built-in router. I don't think this one does. – Marcks Thomas Jul 9 '14 at 22:59
