I am not sure you are going to find that on a router with factory firmware. The way internally the device is built it really doesn't know if it got traffic from the wireless radio chip or the switch chip.
To accomplish this you would have to define the wireless to be in a different subnet/vlan than the wired ports.
Now there are likely some semi commercial routers that might be able to do this but I don't think any of the consumer ones have that feature. You are somewhat lucky if the router can even filter traffic in the first place.
I would look for something that you can load dd-wrt, many of the tplink and asus routers support it. There are some brands like buffalo that preload dd-wrt but I would still buy a router and load it yourself. Loading the software is the easy part, it will be learning to use it to configure what you need that will take a bit of time.
