To help keep the peace, I'd like to establish two separate networks using routers I already have. I think I have my head wrapped around this, but I'd like to have more experienced minds take a look at this so I can be sure I have it right before proceeding.
My current home network consists of three routers providing access to my roommate and myself, all through Mediacom as our ISP. My current physical setup is:
DHCP is currently handled by router 1, with DHCP disabled on routers 2 and 3 and each assigned static IPs through their respective setup pages. I have router 1 currently set to start assigning IP addresses one address higher than router 3 (192.168.11.4 is the first available IP address). The switch is unmanaged and is present simply to provide extra LAN connections for multiple PCs and game consoles located in the same room.
My devices (server, multiple PCs, phones/tablets, game consoles) use the wired connections from router 1 and the switch as well as the wireless networks from router 1. My roommate uses wireless from routers 2 and 3 for his PCs, phone, tablet and game consoles.
I'd like to create one network for router 1 and the switch, and a second network for routers 2 and 3. That way my roommate can tinker with his own routers (2 and 3) to his heart's content. I'm also hoping to isolate all of his devices from my network and vice versa. We do not need any sort of file sharing between our respective devices.
If I'm not mistaken, I can keep everything wired up as is, and simply make some changes in the routers.
Router 1 currently uses 192.168.11.x for IP addresses, with .1 being its own IP address. I think I can leave that one alone. Which (finally!) brings me to my actual questions.
To create a separate network for my roommate, can I go into setup for router 2, re-enable its DHCP and change its IP address to 192.168.1.1, then access the setup for router 3, leave DHCP disabled, and change its IP address to 192.168.1.2? With the 3rd octet being different, can I have DHCP from routers 1 and 2 without any conflict? And will this keep our networks truly separated out from one another, so I can't "see" any of his devices from any of my devices and vice versa?
Thanks in advance for helping me get this clarified and for correcting anything I may have misunderstood in creating two separate networks.
My current home network consists of three routers providing access to my roommate and myself, all through Mediacom as our ISP. My current physical setup is:
Mediacom cable modem Cisco 2100 to WAN port on router 1.
Router 1 - Buffalo WZR-1750DHP.
Switch - D-Link DGS-1008G from LAN 1 on router 1 to LAN 1 on switch.
Router 2 - Linksys E2000 from LAN 2 on router 1 to LAN 1 on router 2 (via a 50' CAT5e, fished through the wall, and routers 2 and 3 in a completely different part of the house than router 1).
Router 3 - Linksys WRT120N from LAN 2 on router 2 to LAN 1 on router 3.
