I can neither discover other devices via laptop bluetooth nor discover my laptop from other devices. Presently installed driver is Net work driver 1705. I tried installing 1704 bluetooth but it is asking to activate bluetooth using wireless switch. The wireless switch can toggle airplane mode but it can't help installation. Tried driver from Widcom site.It asks please plug in or turn on bluetooth device . Please help. Running Windows 8.1 Pro. See the log.
