I have recently purchased a SONY STR DA 1800 ES receiver but will use it only for audio not for video. I have connected a number of audio components and, with GUI mode in the OFF position, see all relevant functions on the unit's display panel. Unfortunately, I do not see the Network settings on the menu when viewed on the display. The manual describes the wireless LAN setup procedure only as viewed on a TV screen. (The TV is in another room and cannot be readily moved or connected to. The room in which the receiver is located has no space for a TV). Is there any way I can connect wirelessly to my computer while following instructions on the receiver's display panel? Can anyone help?
