1. Power down your routers and your modem and disconnect the modem from any router that it might be connected to.
2. Do the following steps with one computer connecting to each router and no Internet connection. Computer 1 to Router A, and computer 2 to Router B. Neither of these should be to Router Port 1.
3. Connect to each device via its computer and make the following configuration setting
Router A
Local IP = 192.168.1.1 (This is usually on the setup screen)
WAN or Internet should be set to Auto (Also usually on the setup screen)
DHCP – Enabled (Usually found somewhere under Advanced Routing.)
Operating Mode – Gateway (Also usually found somewhere under Advanced Routing.)
Router B
Local IP = 192.168.1.2
WAN or Internet should be set to Auto
DHCP – Disabled
Operating mode – Router
4. Power down both Routers.
5. Connect your Modem to the WAN port on Router A.
6. Turn on your modem. Let it establish connectivity.
7. Power up Router A.
8. Connect to Router A and do a DHCP client Release and Renew (Check under Status)
9. You should have an Internet connection from Computer 1.
10. Connect Router A to Router B via Router Port 1on each unit.
11. Power up Router B.
12. Connect to Router A and do a DHCP client Release and Renew.
13. Computer 2 should now have an internet connection.
14. Connect the rest of your computers to the remaining ports on either Router.
15. Check them for connectivity.
16. If necessary, do a DHCP client Release and Renew on each Router after connecting all computers.
17. They all should have Internet connectivity.
18. One problem though, and that is, any computers connected to Router A will not have access to the setup screen on Router B. Here’s how to fix that.
19. DO NOT POWER ANYTHING DOWN.
20. Disconnect the modem from the WAN port on Router A and connect it to the WAN port on Router B.
21. Now everything should work.

Why? Because Router B, which is operating as a router not a gateway, will send the Internet data to Router A, which B recognizes as the Gateway and the DHCP server via the Port 1 uplink. Since nothing was powered down during the modem switch out all the IP addresses for the WAN connection are still sitting in Router A.
Remember if you must power things down, when powering back up, Modem, Router A and lastly Router B.
