    It all depends on "how" you want to extend the range of the Comcast modem/router.

     

    IF.....you can locate a single AirPort Express in the remote location where you need more wireless signal coverage......AND......connect the AirPort Express back to the modem/router using a permanent wired Ethernet cable connection......THEN.....the AirPort Express can be set up to create a wireless network using the same wireless network name and password as the modem/router.  When you do this, then the modem/router and AirPort Express will act like one "big" network with much greater range.

     

    IF......you cannot run the Ethernet cable from the remote AirPort Express back to the modem/router and leave it permanently connected, then your only other option would be to use two AirPort Express devices.  One Express would be located near the modem/router and connect using a short Ethernet cable. This Express will be configured to "create" a wireless network.

     

    The second AirPort Express could then be configured to "extend" a wireless network and wirelessly repeat the signal from the first Express.....assuming that the second Express is located where it can receive a strong wireless signal from the first Express.
