Welcome to the Apple Support Communities
Unfortunately, you have to connect your AirPort to the Ethernet port of the modem. You can use it to extend the wireless signal only with another AirPort Extreme, AirPort Express or Time Capsule

The best solution might be to add an Ethernet switch to your router.

Hi, does this mean that the Airport extreme is not a range extender via wifi? Does a second Airport station help to extend my network, but do i need to connect the second station also to the modem via ethernet, or does it extend the signal of the firts Airport via wifi? thanks.

If your objective is to connect two devices which support only ethernet to an existing WiFi network, you could do so by configuring an AirPort Express (for example) in Client mode connected to your existing WiFi network. Then you could use the LAN and WAN ports on the AirPort Express to connect your dish receiver and DVD player. This concept is called "bridging" rather than extending a network, but in your case I think it is what you need. This solution does not provide you additional WiFi service at your devices, it simply serves as a "wireless ethernet cable" back to your modem/router which creates your wireless network.
Could do the same with an AirPort Extreme Base Station I believe, if you needed more than the two ports.
If I have misunderstood your requirement, I apologize.
