Another update: Now it lets me connect with the TV still connected to the wifi router but the laptop has to disconnected from the wifi router...this really is a head scratcher and I agree Microsoft or LG or both need to figure out what the issue is because this is completely unacceptable that so many people are struggling with this.

Yes, you are correct and I was just going to make a note of the very same thing here. Sorry for any confusion I it may have caused.

Just thought I would post my experience and solution here and hope it helps some: My quick solution (so you don't have to read all the details): Disconnect TV and PC from wifi router and let the two connect directly. Screen Share uses Miracast and it is a direct wifi connection (no router needed). Now the long story: I was having similar issues where I couldn't connect to my new LG TV (WebOS 3.5) with Screen Sharing and an all updated Dell Windows 10 laptop. Well actually I could, it would work about 5% of the time...that's 5% not 50% so it was very frustrating and most of the time on the failures the laptop would lockup and I would have to hold the power button down to shut the machine off. After reading some of the solutions here and reading some other threads elsewhere the thing that made a light bulb go on was when I read that Miracast is a DIRECT wifi connection between both devices...No Router Needed. So like some have suggested, I disconnected my TV from the wifi router and disconnected my laptop from the wifi router and let the two devices conduct their hand shakes and whatnots directly without a network router middle man. IT WORKED!!! Once the screen sharing worked I connected both devices back to the wifi network router and all worked great (except the LG TV did not remember the wifi password and I had to re-enter it). Side note: I am one of the few people left in the world with a Windows 10 phone and the Continuum app on it connected 100% of the time regardless if either was connected to my wifi router or not. haha I love my windows phone, lack of apps or not it does what I need it to do...hope they follow through on the Surface phone or "Andromeda" phone or whatever it will be called. Hope this helps some out there.
