Originally connected radio to the Netgear wireless router. Played music for about 15 minutes then lost connection. Now it won't find any wireless networks. I've rebooted the router. I've reset the radio to factory defaults. I've reinstalled the firmware on the radio using wired connection. The radio will not find any wireless networks. After the radio boots up the radio turns on and says lets start by getting you connect to your network, I hit continue, next it reads not connected...we can't detect a wired connection please check your ethernet cable. There seems to be no attempt to look for a wireless connection.  I've tried a second Linksys router to no avail.
