just the other day when i was playing xbox i randomly got disconnected. i then tried to reconnect so i could get back on but it didnt work so i tried turning off my router and turning back on, still didn't work. i unplugged the ethernet cable and made sure the ports were open on the firewall, still it didnt work. so i waited overnight and tried everything over again in the morning but still no luck. And if this helps: when i turn on my xbox, it logs me on to xbox live then about 3 minutes after i turned it on i get disconnected. the same thign happens when i turn it off and back on. please somebody help me.
