If you run your data at a speed of 6.4 mb and you are getting freezes then you have other issues but not a speed factor, I have 2mb and it runs flawless.I have 6.4 Mbps and freezes every 30 seconds for about a minute or so. Have tried Voodoo and rocket IPTV. Both work the same way. Any ideas? What should the buffer be set to?
