Before replacing the router, you might download and install the latest
firmware from the support page at <http"//linksys.com>

I just checked my own router to see if it had the option to disable
certain ports in the QoS config, but it only allows ports to be set at
a High or Low priority. I don't see anything about completely
disabling them, and I assume yours is the same. Even so, as has been
suggested, it probably wouldn't hurt to do a full reset to put
everything back to factory defaults. Either stick a paper clip into
the reset hole or reset it via the Admin page.

So far, it was sounding like ports 2-4 are dead, but you said ping
works through each of them, so they aren't dead after all. *shrug*

I tried both reseting the router with a paper clip, as well as upgrading to
the latest firmware. No joy.

Bought a wired/wireless router this am...

I ran multiple pc's using that same router before I upgraded to wireless. I
didn't have to do anything except make sure the router and all pc's were
configured for DHCP. You might want to do a reset of the router to get it
back to factory settings in case osmething has been changed. Then just
make sure it's set for DHCP. Check the pc's for DHCP too.

The cable modem is probably a SB5100, I hope. :)

Not much to go on here, but the basics are that the router's Internet
port, sort of off to one side by itself, should be connected to the
cable modem, and the PC(s) should be connected to any of the ports
labeled 1-4. The PC(s) should be configured for DHCP, (easiest to get
working; you can do static IP assignment outside of the router's DHCP
range later.) Power down the cable modem, the router, and the PC(s),
then power up the cable modem and let it stabilize, power up the
router and let it stabilize, then power up one PC at a time. Make sure
there are Link lights at both ends of all live (powered up) cables.
Rule out a bad patch cable. If Port 1 works on the router, but 2-4
don't, you may have a bad router. If you have all of the necessary
Link lights, see if you can ping the LAN side of the router from the
'bad' PC, (usually at 192.168.1.1), and if that works, ping the cable
modem, (usually at 192.168.100.1). The ping results will help you
determine where to go next.
