SMART BRO Plug-it is a wireless USB connection that has problem with youtube, It sounded like a crack radio and it has low quality even though in normal. I used different SMART BRO Plug it and the problem still persist. It is ok in LAN connection.
Last night I checked the "Ipv6" "Internet Protocol Version 6" in the SMART BRO Properties, and the problem was gone, but right now I can't check it and I when I try reconect it, it disables
