Unable to connect all computers to cable broadband

Archived from groups: microsoft.public.broadbandnet.hardware (More info?)

My family recently upgraded from a DSL connection to a
Cable one. We used a Microsoft MN-150 switch that allowed
all 4 home computers to access the same broadband
connection.

Since we have upgraded to cable our switch no longer
allows us to have all PC's access the net.

I plug the ethernet cable from the cable modem into the
#1 port on the MN-150 switch and the others into the
remaining ports but I am only able to get net access for
1 PC.

I have done everything exactly the same as I did when I
had dsl with the obvious exception of not using the DSL
modem.

Any and all assistance is greatly appreciated as I have a
few grumpy people in my household at the moment !!
