Access to 2nd Router

post #1 of 18
Thread Starter 
Hi guys,

I have difficulty to access my 2nd router via LAN connection. My current network is like this:

1st modem router (netgear based modem router)
- Currently connects to internet
- Have 2 active LAN connection, say PC (A) [192.168.0.12] and PC (B) [192.168.0.13]
- 3rd LAN port is used by the 2nd router
- Current IP address is 192.168.0.1
- Subnet mask: 255.255.255.0

2nd wireless router (netgear based wireless router)
- Hosts wireless and LAN networks
- Currently connects to 1st modem router for internet access via 192.168.0.10
- Current IP address is 192.168.1.1
- Subnet mask: 255.255.255.0
- RIP Direction: Both
- RIP Version: None

I can't connect from either PC (A) or PC (B) to 192.168.1.1.

Do I miss anything here? headscratch.gif

what do you mean by "connect"? Are you talking about a virtual settings page like belkin uses through 192.168.2.1 in a web browser or just connecting to the network? and if your IP addresses are correct then it skips 192.168.0.11 Not sure if that makes any difference.

Change the IP address of your second router so it's on the same subnet as the first one: e.g. 192.168.0.2 or something then make sure it's connected to the first router via it's LAN port instead of the Internet port.

I am trying to access my 2nd router setting page on 192.168.1.1. My problem is that all PCs connected to 192.168.0.x subnet are not communicating with the gateway on another subnet (i.e. 192.168.1.x)

The 2nd router is connected to the 1st router via LAN port, not internet port. I may try changing the 2nd router LAN IP to the same subnet as the 1st one, and see how it goes.

One thing that gets me curious is that how devices on 192.168.0.x cannot communicate with devices connected on 192.168.1.x.

Tried that and it showed this error message: "The IP Address conflicts with the WAN IP Subnet. Please enter a different IP address".

It looks like the LAN IP for my 2nd router has to be on a different subnet. So we're back to square one.... frown.gif

why dont you try using a different private address such as 10.4.4.1 255.255.255.0 thinking.gif

Because they're on different subnets. You'll need to put in some static routes if you really want it to work. Easiest to just have them all on the same subnet though.

Try changing the WAN IP to something else if it's conflicting.

Take a computer and set its it address to something static that is in the same subnet as your second router. Then go into that routers settings and disable the DHCP server, and set its IP address to something that is in the same subnet as the first router, but outside of its range that it assigns IP address. If your first router is 192.168.0.1, make your second one 192.168.0.252. That way the primary router is is assigning the IP addresses and the secondary router is simply getting its instructions from the primary router.

EDIT: After you are done configuring the second router from the computer, plug it back into the main router using the LAN ports on the back, not the WAN ports. Also set the computers ip back to attain IP address automatically.

Problem is you're in a double NAT scenario. All traffic from router 2 subnet is being sent out the singluar "WAN" IP of router 2 (an address in router 1's subnet). No inbound traffic exists as you must port forward or originate the connection from a device on router 2.

To alleviate this, assign a static LAN IP for router 2 in the same subnet as router 1 and outside of the DHCP range of router 1. Disable DHCP on router 2 and connect the routers together using a LAN port on both devices.

Now, everything will be in the same network and reachable from any device, while not having to traverse PAT.

Thanks for pointing this out to me. thumb.gif

Both of you suggested that I turn off DHCP server on the 2nd router. I am currently using my 2nd router as a wireless router for devices like tablet, mobile, consoles, etc. Will I still be able to use my wireless connections on 2nd router?

Both of you also suggested that the 2nd router should be connected to the 1st modem router via a LAN port, instead of a WAN port. Will all wireless devices connected to 2nd router have internet access?
