I checked and under Advanced Options, then Quality of Service on the left side you can prioritize the devices.
Another thing ocurred to me. The Verizon box where the fiber optics line comes to the building has a network connection in it. Mine is hooked up via coax coming from that box but it'll work via a network connection as well. I've considered plugging the Linksys straight into the box to see if it would connect but haven't gotten around to it. My guess it it wouldn't. But perhaps running a network cable to the Actiontec would be beter than coax.
