Factory reset will clear all old settings, you need a straight through ethernet cable though not a cross over.
How to factory reset the router.

Hold the reset button on the unit for 30 seconds or more and the router will be restored to factory defaults. This also means that your configuration will be set to factory defaults also, so if your router is configured for your ISP you may loose your connection until you set the unit up again. The default password for the router is admin in lower case letters

Then try this:
Power off the cable modem,
power of router
power off PCs
connect all together (sacm to WAN port on router)
power up SACM (modem)
let the lights settle
power up router
let lights settle
power up pcs
If that doesn't work then your may need to clone your currently connected PCs MAC address into the router but that isn't difficult to do.
