I recently bought a Denon AVR-1912 Receiver. I would like to provide internet access to it through my wi-fi network so I can easily access firmware updates and try out its online services. However, I understand the receiver does not have a wi-fi dongle, just an ethernet port. I've also heard that there are ways to "work around" this issue, though I don't know how. What are the specific ways to work around the absence of a wi-fi dongle (aside from using a hardwired Ethernet connection)?
