Hi, I recently bought a new WRT1900ACS router and my goal is to cascade it with my Lynksys E4200 v1. My 1900 will be the main and the 4200 the secondary. I am cascading it wan to lan to create 2 separate networks that cannot communicate. I understand how to do this but I have a couple of questions. I want to limit the 4200 to 30% of its total up/download speed and I'm assuming I need to use QOS. Since the cable from the first is plugged in an ethernet port and the 1900's end plugged in to the Internet port I'm assuming that I need to adjust the 1900 ethernet port that's being used for that. How do I do that without interfering with the other ethernet ports? What settings? Do I use E4200's MAC address? What other settings? I'm lost and I need help obviously. The second router is for kids. Thanks ahead of time!
Step 1: Check and take note of the IP address of the main router.
Step 2: Connect your computer to one of the Ethernet ports of the secondary router.
Step 3: Access the web-based setup page of the secondary router.
Step 4: Under the Basic Setup sub-tab look for IP Address or Local IP Address.
NOTE: If the IP address is the same as the main router change the fourth octet (the number in the fourth box) to a different value. Example: Main router: 192.168.1.1 -> Secondary router should be: 192.168.1.2 Step 5: For the DHCP Server Setting set the DHCP Server to Disabled.
Step 5: Click Save Settings.
Step 6: Unplug the cable from your computer and connect it to one of the Ethernet ports on the main router. Make sure the main router is still connected to the modem via its Internet port.
Step 7: Powercycle the secondary router and once the Power light is solid check whether you're able to access the Internet on your devices.
