modem (4 port router) to switch

I've just installed a switch after my modem/router to be able to connect
more pc's to my internet connection. The problem is that the connection
through the switch doesn't work. Even If I connect only one pc with the same
settings as if I connect it directly at the modem, notting happens...
I've read the instructions of the switch (LinkPro SOHO Switch 5) and it
says that there is no need of a crossover cable since all the ports support
Auto-MDI/MDIX function.

any suggestions or configurations???
thanks

Can I assume by "after" you mean on the LAN side?

Did you try a couple of different ports on the switch to rule out the
possibility that one is bad (it happens)?

Are you sure all your cables are good? (especially the one from the
router to the switch, and whichever ones you weren't using before)

Are there any status lights on the modem or switch?
What do they tell you?

The switch is powered up, right?

.... it should "just work."

Sounds like the 'switch' is actually a router, and needs to be
configured so that it knows where to look for its 'parent' machine.
You say 'modem/router'. These are different things.
The usual "cable modem" is dumb. The usual "DSL modem" is dumb. And
neither is actually a 'modem' like you use with dial-up.

If you hang a switch/router behind the modem, it must be told where to
look for the ISP's gateway and for the DNS servers.
Internally, your machines need to be given a default route to the
switch if you are using static IP's or set to use DHCP. If DHCP, the
switch/router must actually be serving as a DHCP server.

AND: the switch/router machine must be able to talk to the ISP using
PPoE or PPoA or whatever.
If the switch/router can't do that, then it should live behind a
dedicated machine which can translate your traffic.

He told us a make and model -- if this is it, it's a switch:

Yes the switch is connected after the modem/router (4 ports), that means
after the port on the lan side.
I've tried all the ports, and I'm practically sure the cables are all right.
The Switch leds says me
on the uplink cable: only the Link/act led on
on the cable connected to the pc: all leds are on (Lin/Act, 10/100M, Full
Duplex)

That all seems correct. Is there a particular error message you are
getting when you try to connect that might help us figure out what's
wrong?

When you try to connect, do either of the activity lights blink?

Try powering off the switch (after all connections are made and with
the PC and modem both powered up), wait a couple of minutes, then power
the switch back up (so it will reload its tables).

Very curious ...

Also, try the crossover cable, even if it says auto MDI/MDIX. I spent
a week trying to fix a similar problem, then used a crossover cable
and all has been stable. It worked part of the time, that was the
frustrating thing.

Yes, and it appears that it is a dumb switch in that it has no setup
capability.

He might be able to get it to work if all the machines behind the
switch are set up to talk natively to the ISP (through the 'modem')
but I would not bet on it.

Usually switches are intended as pure passthrough entities like a hub
(but without the bandwidth sharing deficiencies of a hub).

This may never work for what he wants. He probably needs a router
(with PPoE or whatever) between the switch and the modem.

FWIW, I think he says he has a router. As I recall, he also says his
setup works without the switch in the circuit, but won't work with
the identical PC run through the switch. That suggests to me that
there's something wrong with either the switch or the extra cable
needed to connect it.

The guy who suggested trying a crossover may be right -- those
auto X-II things may not be terribly reliable (even though the
status lights seem to indicate he's connected).

Also FWIW, I've had trouble with cheap switches before (not the
one he has, though -- I've never tried that brand).
