It is STRONGLY recommended that you do not use 2 routers. You may want to return it and purchase an access point (wireless) or a hub/switch.
To use your router as an access point only, please follow the steps below:
Router A is the router you want to use as the router - connected to the modem.
Router B is the router you want to use an access point or switch.
Step 1 Do not use the WAN port on router B.
Step 2 Depending on your network setup, you may need to change the LAN IP address of router B. The default is 192.168.0.1. If you are using another router, DHCP server, or Internet connection sharing software, change the LAN IP address of the router to an IP in your subnet (192.168.0.2). The LAN IP address must be static.
Step 3 Disable DHCP on router B. To disable DHCP, go into the routers configuration > Home > DHCP. Click Disable and then click apply.
OK .. I am glad to start explaining ... 2 Routers and Computers
required Configurations .... so that you can try test them.
1- First of all If you want to make Communications between
Two Computers only without Routers ... We connect them by a Cross Cable , and each Computer must have its own IP been Configured to let the Idea work.
And Now You Can Test ... If Communications are reachable or
not , between both computers By :
1.1- Using Ping Command from Cmd prompt from A to B.
1.2- Or Running a VB6 winsock server on Computer A ,
and a VB6 winsock Client program on Computer B
and Test if Client request reaches the server and the server
accepts it then Send message from one side to the other
2- If you want to Use Routers ..... Here we Go :
But Here Ordinary Cables are used Not Crossed.
I assume Router A is Connected to Computer A .
and Router B is Connected to Computer B.
and also Router A is Connected to Router B.
So we need 3 Cables for making Connections :
2.1- One Cable is to Connect Computer A to One of the LAN
ports of the Router A .
2.2- Second Cable is to Connect Computer B to One of the LAN
ports of the Router B .
2.3- The third Cable is to Connect WAN Port of Router A to the
WAN port of the Router B.
Now I assume My settings for IP addresses for each device:
