If you're asking how to connect your BRDVD3 wirelessly, just get the cheapest wireless bridge or gaming adapter you can find. You can also convert many wireless routers into bridges by loading the free DD-WRT firmware (google it and see the list of supported routers). That's what I've done using a $30 refurb WRT-160N router from amazon with a couple of my BRDVD3's. HERE's another cheap bridge that will work.
If that doesn't work for you, just exchange your BRDVD3 for a WBRDVD like XPDosher said and you won't have to buy any bridges or adapters.
Good luck.
