Trying to stack my network lan


To all,

I have a comcast momdem/router (10. network) and i also have a Buffalo router(192. base addr) now I am trying to get my comcast router to stack with my buffalo router. To date I think it sort of works, but
i powered down all routers, then powered up the comcast first, waited until it booted, then powered up my
buffalo router.

Then i logged onto my computer hooked to the buffalo router and did a ifconfig -a. To my surprise the
ip address was 10.0.0.5? Why is this, how do i re-configure my computer system to a 192. address so
I can log onto my buffalo router and reconfigure it?

Merci,

How are the routers connected together and what are you trying to accomplish?

MichaelK, the Comcast router is hard wired into Port 1 of the Buffalo router, my computer is hard wired into port 3.

The comcast router does send out a wireless signal that i need for laptops down stairs. i want to move the buffalo router upstairs and then push wireless and wired upstairs.

Thanks for asking.

So you really want the Buffalo router to be wireless access point. You should disable DHCP on the Buffalo router and keep everything as 10.x.x.x.

A better option if possible would be to configure the Comcast router in bridge mode so the Buffalo will function as the main router using its WAN port.

MichaelK,
I don't want the comcast router to stop wireless. I want the comcast wireless to handle downstairs traffic. My next issue is, "is there a way to stream direct wireless signal"?
and i want the buffalo to be able to handle the upstairs traffic? wireless and wired.?

or am i desiring way to much of my wireless equipment?

Ok, thanks for the clarification.

Disabling the DHCP server on the Buffalo should be sufficient and I might use a different SSID for the wireless.

I believe that the set up you want is:
Code:
Internet --> Buffalo --> (wired) --> PC
              |
               --> Comcast --> (wireless) --> laptops
For this to work, you need to have these router settings:
1) Buffalo router gets IP address by DHCP and acts as DHCP server to the LAN
2) Comcast router gets IP address by DHCP but does not act as DHCP server to the LAN

Turn on the the Buffalo router first. It should get an external IP address from your ISP via DHCP and an internal address of 192.168.1.1
Turn on the Comcast router second. It should get an internal address in the 192. address space from the Buffalo router via DHCP.

What happened here was that the Comcast connected first and started to act as a DHCP server to the LAN. When activated, the Buffalo requested an address by DHCP that was supplied by the Comcast from the 10. address space.

The Comcast is also a MODEM so they need to be swapped in your pictorial.
Both routers are wireless.

I am happy to be corrected, but perhaps it is best to let the OP adjudicate.

allend,
I was directed by the telcom guys at COMCAST to turn their router on first........

but what your are saying makes better sense to me. Will this give me the ability to log on to my bufalo router and configure it?

merci beacucoup,

I assume it is a combination unit.

In order to log into the Buffalo router you will need to disconnect it from the Comcast unit (stand alone) and plug a computer in to its LAN port. This will allow the computer to acquire an IP address via DHCP. You can also manually change the computer to match its LAN network if known ( Should be in the instructions).

If you swap '2-wire' for 'Buffalo' and 'Comcast' for 'Netgear' in the pictorial in post#7, you have a setup that I have been running recently. Your Buffalo router should be present on the network and accessible from any computer on the LAN.

To reconfigure the Buffalo it should be disconnected from the Comcast router to make it easier...
