We have an 8 node Lan (Linksys router) at work
that uplinks to a Wan Cable router (not a cable modem)
provided by our cable ISP.
We used to have a cable modem for our Wan, of
which then we utilized the wan port on the Linksys
router to jump to the cable modem data port. However
when the ISP upgraded to the cable "router" there is
no data port, just 4 different ports labeled Lan1, Lan2 etc.
So now we jump from the uplink port on the Linksys
router to the 1st port on the cable router. We leave the
port right before the uplink port on the linksys port
empty (common knowledge item).
Ok here is the dilemma. All of the nodes that were on
the old cable modem/Linksys or Wan/Lan now boot
up and work flawlessly on the new topology. I.e. they
can see each other on the Lan "and" they can get out
thru the cable router uplink to the Wan internet. But
we have added two new nodes that were not on the
old system. The configure pretty much as expected in
setting up the network connection. One is a Compaq
the other is an Emachine, both run XPhome. However
the two new machines can see the Lan (and we can see
them) but they cannot see out thru the cable router uplink
to the internet. I've flushed the ipconfig caches, and rebooted
to exhaustion. These two refuse to see out. If I switch
data cables with two other nodes on the lan, then the nothing
changes, the two nodes that did not see Wan "still" do not
see Wan and the two that did see the Wan "still" see the
Wan even though they are in the same Lan hookup scenario
as the two that did not. We are at our wits end with these
two machines. We called a computer shop and they said
we should reload windows to reset everything.
Is there any other solution?

To use Cable Internet you *NEED* a modem. Most Cable ISPs are DOCSIS compliant so any
DOCSIS complaint Cable Modem can work with their network.

You would then use a Router. I'm not sure if you are using a Linksys BEFSR81 or what model
because you failed to post this data.

I say again as previously posted,

There is no Cable Modem. All nodes work except
two.

I will fetch that but it will be at least Tuesday night
before I can repost since both are at work across
town and we are off Monday. I do have that info
written down on a sticky note though.
Sincerely confused.

I thought that XP Home only supported networks with up to 5 machines.
XP Pro supports up to 10 machines. If you need more than that on your
network, you need the 'Server' software. I'm not typing this based on
my knowledge, only on what I have seen in this newsgroup. I may be
wrong, but if I'm right, you'll need to upgrade to xp pro on those two
machines. Maybe someone else can chime in here and verify my thoughts
on the matter.

I apologize for my ambiguity. I was specifically
wrong in my description and you were specifically
correct in your statement about the modem.
To correctly start over, it is an ISP provided
cable router/modem. It has a coax out going to
the cable hookup and it has 5 LAN ports and
1 uplink port. We have our nodes into the linksys
and the linksys is uplinked from it's uplink port to
the LAN_1 port on the ISP router/modem
>Please post the model numbers of both devices.
Linksys BEFSR81 CABLE/DSL ROUTER
and
Zyxel, Prestige 900 series is our ISP provided cable router/modem

OK. Then you don't need the BEFSR81 (BTW: That's what I use) what you need is just a 8 or
more port Ethernet switch. The Prestige and teh Linksys Routers will cause configuration
disfficulties because you are essentially using two Routers.

Either you replace the Zyxel, Prestige 900 with a plain DOCSIS cable modem (not suggested
unless you register it with the ISP) or you replace the Linksys BEFRS81 with a 8 or more
port 10/100 Mb/s Ethernet switch (that's my suggestion).

-------------------------------------
I've wondered about that. I do have a extra 5 port
linksys switch (not a router) in the cabinet. That
would give me 4 ports with an uplink to the ISP
router/modem which has 5 more (total) ports.
I will try that first, if that doesn't work I will have
to order a 8 to 10 port switch on the net since I've
never found any here in town with that many ports
at a retail outlet. There are some at specialty computer
stores that are very expensive (having 20 to 50 ports).
While I have your expertise here, can you tell me
what some of the ramifications are when using two
routers in a topo. Obviously this creates a sort of
Wan within the Lan correct. Is there software
(without spending a fortune) one can buy to manage
such setups?
Additionally I'm concerned about the ISP router
working as a normal router since it's ports are
labeled LAN-1, LAN-2 etc. It's almost as if it's
a gateway between different switched hubs. But
then from what I've seen so far that would be
no different than a single node as long as no
router was involved.
Thanks much for your input. I'm a civil engineering
cad draftsman by trade but elected as Net
administrator at work since I know enough to be
a hack of sorts but really I'm an amateur at Networking.
