I found the problem to be that the TV was on 2.4 ghz and my Surface on 5 ghz. I change the Windows 10 device to 2.4 ghz and it works every time. However, I won't use it much because I want my Windows 10 device always on the fastest speed possible.

Thanks ChrisG, that worked for me (after going back and forth with LG tech support for two weeks)
