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?
