Get an Ethernet "switch." They cam be had as cheap as $20. Thi will add another 4 ports (for a 5 port switch.) You simply daisy chain one port of the switch to one of your router ports. Connect the Microcell to one of the router ports directly and move something else off on to the new switch (for best performance.) You'll need to get another network cable to uplink the switch to the router. Edit:Whoops. Sorry. Ed already answered, sorry. I missed that as I'm reading on a mobile screen.
