Solved No internet access on third router

October 20, 2012 at 22:58:23
Specs: Windows 7
I have High Speed Charter Internet going to a modem in form of coaxial cable with one Ethernet port available and one coaxial connection for TV and a phone jack. I have that Ethernet port connected to a:

Motorola Wireless Modem
[IP: 192.168.0.1 DHCP: enabled]
wireless on
with four Ethernet ports available.
located next to the modem.

The first of four ports I have connected to a
D-Link (655) router
[IP: 192.168.1.1 DHCP: enabled]
wireless on
with four Ethernet ports available.
two computers connected via Ethernet
located 60 feet from the modem.

The second of the four ports I have connected to a
Linksys WRT54G
[IP: 192.168.2.1 DHCP: enabled]
wireless on
with four Ethernet ports available.
located 60 feet from the modem

Questions:

1. Are there any obvious errors with this configuration?

2. Why is Linksys the only one not able to access internet?

✔ Best Answer
Question: Is there a need for the separate subnets?

If not then I would suggest you connect the downstream router's LAN port to LAN port with the Motorola, and give them LAN TCP/IP settings something like the following:

Router 2 (D-Link)
IP: 192.168.0.2
SM: same as Motorola
Default Gateway: 192.168.0.1

Router 3 (Linksys)
IP: 192.168.0.3
SM: same as motorola
DG: 192.168.0.1

If you have to have separate subnets for some odd reason, then you must have something configured incorrectly because your setup looks good to me. The only thing I can't see is the WAN port configuration on the Linksys....you could have something incorrectly configured on that interface (gateway address or maybe subnet mask). I would compare the WAN settings on the Linksys to the D-Link. The only setting that should be different is the actual IP address. The rest should be the same.

The route from 192.168.2.0/24 to 192.168.0.0/24 should be created by default on the Linksys router and it should work. I would say look at the routing table and if that route looks correct, I would say reset the Linksys to factory defaults and try reconfiguring it again.

I have a "how-to" guide I wrote that may help. To see it, click on my name above in my response and look for the "adding a second router" how-to.

It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.

I got it working! Turns out there was no internet running to my 3rd router. Reason being, faulty cat 5e ethernet cable. I must have done 30 trips up and down my crowded attic!! Finally I ran store bought cable and it worked great! With the configuration I posted. Thanks guys for your speedy reply, I'll do my part by answering people's question!
