Dell 4610x Wireless Plus network drop outs

Hi, We are currently using the Dell 4610x as our projector in our office. Our current setup is that the projector is connected to our network via a cable, People connect to the projector by connecting via wireless using a Linksys wireless access point and then to the projector via the network cable. The problem we are having is that every now and then the connection to the projector is dropping out and we are having to turn the projector off and on again or we will need to unplug and replugin the network cable. Has anyone else experenced network dropouts with this projector or has any solutions to the dropouts.
