Ok, so lately ive been lagging on Xbox live. I have tried EVERYTHING to fix it. Used different Ethernet cables plugged directly into the wall, I've tried different xboxes I have forwarded ports I've call my ISP like 20 times and they say everything is
fine they even came out to my house to check it. My speeds are 20 Mbps down and 4 up. I literally have tried everything and nothing has worked. My other friends have the same ISP and they don't lag... I don't know what else to do. Any help?
