Presently have the LINKSYS router with 4 ports. I have 4 machines tied to this router, and ( WOULDN'T YA KNOW IT), need to ad a 5th computer here. Is there any, possible way to add another computer to this router without ditching the router and going with a 5+ port model. System works great now, I do not have all computers running at the same time..would hate to think I can just unplug cable and plug into system I am using, but would like some options. Any thoughts....??
