Hello, This may seem a little strange, so if you don't understand my question(s), please ask me to supply you with more information. My PC & my wireless router are in my office in the basement. I have my entertainment system, including my Sony Multi Channel AV Receiver - STR-DA6400ES, which I can connect to the internet via a networking cable, up two levels in my Entertainment room. I cannot run a networking cable from the basement to the top floor of my house. Is there anyway I can connect my Sony AV Receiver to the internet? I would really appreciate any and all help regarding my problem. Thank You.
