2 Routers 1 Network

post #1 of 11
Thread Starter 
Hey guys,

So recently I decided to put another router in upstairs as we were having a bit of a flakey connection to the one in the basement.

I have a connection from both points, however I can no longer see the computer downstairs in My Network Places. It is important as I am trying to connect a Seagate Media Centre to the system in the basement.

I am able to reach that system by pinging it's IP address.

I was wondering how I can configure the router upstairs (Dlink Dir -815) so that both areas covered are part of the same network.

Router downstairs 192.168.1.254
Router upstairs 192.168.0.1

I tried putting the router upstairs on the same subnet and disable any features, to simply have it as a connection point but kept getting conflicting WAN/LAN error messages.

Any help would be appreciated!

Thanks in advance,
David

Disable the DHCP server on the one farthest from the gateway.

Don't have them both on the same level either, make sure one router is connected to the other, and disable DHCP on the lower one.

Why are the network sections of the two routers IP's different? Why not one router and one switch? If you want to make use of two seperate WAN connections how about a router that has two WAN inputs?

Eww double NAT.

To assist your plight:
  • Give router 2 a static IP outside of the DHCP range of router 1 but within the same subnet
  • Give router 2 similar WLAN credentials but change the channel to something 3+ away
  • Disable DHCP on router 2.
  • Hook devices together using the LAN ports on each device.

Auto MDI/MDIX should take care of needing a crossover cable, but now everything will be in the same broadcast domain.

I tried to give my 2nd router an IP address anywhere from 192.168.1.1 up to 192.168.1.255 and kept getting "The Network id of LAN-1 is the same with WAN-1"

Sorry I'm not exactly sure what you mean by WLAN credentials. Essentially I've got my "Internet" where I chose static IP and pointed it to the router downstairs. "Wireless Settings" For my Wireless, password, SSID, etc... and "Network Settings" where I have my router IP, where I am recieving the area, and my DHCP settings are in there.

DHCP is disabled on the second router.

I have a cable coming from port 2 on router 1, into the Internet port on router 2. Is this correct?

Thanks for the help, I am a beginner to networking and am trying to get my head around this haha.

what kind of routers are they?
how do you have them connected?
are you using the second router as a wireless repeater/extender?

I'd say do a factory reset of the upstairs router so that you start fresh.

1. Assign the LAN interface either an unused IP from the DHCP range of router 1 or an IP outside the range but on the same subnet (192.168.1.100, for example) (or setup a reservation)
2. Connect the basement router to the upstairs router by using a LAN port on each end. DO NOT use the WAN/Internet port on the upstairs router.
2a. If the ports don't link up, get a cross-over cable/adapter or enable auto-mdix like beers said.

You're getting that "The Network id of LAN-1 is the same with WAN-1" error because your WAN interface is getting an address from the basement router's LAN DHCP scope and you're trying to assign the LAN interface to the same subnet. You can't have two routed interfaces assigned to the same subnet (Routing 101). All you want is the wireless and switching capabilities of the upstairs router. The WAN/Internet interface has no place in that.

Finally had some time to sit down and actually do this, I kept trying to do it with half of my mind into it as fast as possible before I had to whip out the door. Ended up
  • resetting router 2
  • gave router 2 IP outside of the DHCP range of router 1 (192.168.1.105)
  • disable DHCP on router 2, for some reason upon the first reset after disabling it didn't function, had to enable it, reset and disable and reset again
  • DONE smile.gif

Thanks for all your help guys, I apologize for being noobish and I feel pretty stupid now that I got it working. Gotta learn somehow though wink.gif
