• Question regarding multiple routers on one modem
    8 replies, posted
Hey. So, my house is pretty big and doesn't have ethernet wiring in it. My room is a floor above and opposite side of the house, so the internet is bad. My total speed is 100mMb/s down and 45-50Mb/s up. Powerline adapters bring me to .7Mb down 20Mb up, and wifi is probably 1Mb down 15Mb up. Anyway, numbers aside here's my question. I'm planning on running an ethernet cable down into the basement through ceilings in floors (don't ask logistics, that's not the issue). My modem is connected to a switch box, which then is wired to the other router. Could I connect a second router to that switch and make it work? I know internal IPs might get fucky so im wondering. Also, does anyone have a good tutorial for doing this? thanks!
Yes. Purchase a new router, disable DHCP on that router, change the internal IP address to something different than the router that handles DHCP, and you're done.
Thanks! Clears up a lot. Was starting to stress about this purchase of a ton of Ethernet cable to wire it down.
Why purchase a router and disable DHCP if it's possible to use a network switch? For example I use an ISP supplied router that handles all configuration and then an unmanaged switch for more ports in the house
Ive got another router sitting around not being used
If you have a chance consider getting a strong ac WiFi router. The one that most companies install isn't meant to have wifi anywhere else but the room it's in.
Hi, I’m trying this currently and it seems that when I set the router to be 192.168.2.1 it totally fucks up and doesn’t allow my laptop to connect. No pings or anything. Router still 192.168.1.1 until I replug it and it then displays no default gateway.
This is what you'll want to do: 1) On your main router, change your DHCP range so that your new router won't have a duplicate address with another device for some reason. 2) Set the local IP address of your new router to whatever in your IP address range. AKA if your main router is 192.168.1.1, make your new router anywhere in-between 192.168.1.2 to x.x.x.253. 3) Connect the routers to each other with an Ethernet cable LAN port to LAN port. It sounds like that you set it up LAN (on main router) to WAN (on new router). 4) You should be good to go. When you connect the routers LAN to LAN, you're allowing the new router to act as an unmanaged switch to transfer data which is the easiest to manage. If you want to connect the two routers LAN to WAN, you will have to enable DHCP and have it address 10.0.0.x or 172.16.0.x with a 255.255.255.0 subnet. When you do it that way, you will run into devices not being able to see each other, and could become problematic if you're running devices that use Chromecast, Airplay, or need a general connection between the two routers.
Thanks for the help Turns out the switch was for TV (was over ethernet) so that's why it wasn't working. I ended up doing some magic with a switch and ethernet cord and now it works. Fast internet! Hurray!
