I have a wired and a wireless routers. I connect them together to make them looking as one router. Then, I can access all the computers within the same intranet.
Router A (connect to the internet)
Step 1 :
I assigned a wired router to be Router A which is connected to the internet via optical fiber. I did nothing on the Router A. The LAN IP is 192.168.0.1.
Router B (connect to the Router A)
Step 2 :
I assigned a wireless router to be Router B and I should change the settings of it.
Set the WAN IP to be static 192.168.111.2, subnet mask 255.255.255.0 and gateway 192.168.111.1, no matter your Router B is wired or wireless. For me, Router B is a wireless. (You can change the WAN IP and gateway to meet your requirement, here is only an example)
Disabled DHCP and set the LAN IP to 192.168.0.200, subnet mask 255.255.255.0, no matter your Router B is wired or wireless. (You can change the LAN IP to meet your requirement, here is only an example)
Step 3 :
Connect Router A and Router B via a cable on LAN ports only. WAN port will not be used at the Router B. Connect Router A to the internet as normal. Now, you can access Router A by 192.168.0.1 and Router B by 192.168.0.200 via your browser. Any computer or laptop will be assigned an IP of 192.168.0.XXX.
That’s all. Enjoy networking!
