Re: No Internet Connection Between Router and Modem

No Internet Dilemma!

Ive been trying to help my friend out for the last couple of nights
with his new home networking setup.
All he wants is to connect to the internet via his laptop over
wireless while having his home desktop PC hooked up to the cable
modem.

So we have the basic bog standard setup (or so id think)

Internet --- MOTOROLA SB4200 SURFboard cable modem --- AzureWave 54g
Wireless 4-Port Cable Router
http://www.maplin.co.uk/Module.aspx?ModuleNo=218646&C=Maplin&U=SearchTop&T=ROUTER&doy=21m8

So After hours of troubleshooting at getting idiotic due to Windows
Vistas unreliability we finally reolised that the router wasnt picking
up an internet connection from it cable modem.

The router does not "pickup" anything from the cable modem. The modem
is a bridge and is transparent to IP addresses. The modem get it's
information from the CMTS (cable modem terminal system), which will
deliver all kinds of nifty things to the cable modem including an IP
address for the router.

You can also connect to the SB4200 at 192.168.100.1 and check the
status page. Got a connection?

Can Vista connect to the router and look at the status page? If so,
does it have a routeable IP address from your cable ISP? If not,
check the WAN settings in the router. You may also have to "clone"
the MAC address of the workstation in order to authenticate.

Im all out of ideas now and thought id try my luck with this forums...
Hope to hear from you all soon
Thanks, Dan

The usual problem is that Vista has changed the way DHCP works. See:

This is only a problem if your Vista machine cannot connect to your
router and see the web based config. I believe there is also a
firmware update on the Motorola web pile to fix this, but I'm too lazy
to check.

When you get that fixed, this may also bite you:
