We are having major disconnection problems with our Xbox Live. We have extensively read all the FAQ's on this forum and tried all the trouble shooting tips. The problem persists.
We activated Xbox Live Gold (Family account) end of Dec, 2012. Service was running flawlessly with Netflix streaming and everything until about a week ago. Starting the last week we are constantly getting booted from Xbox Live. This happens the worst when trying to watch Netflix but we also get booted when sitting on the dash. Sometimes it's better than other, sometimes it'll disconnect constantly after a min or two. And sometimes it refuses to sign in at all.
We have done EVERYTHING. The Xbox is hardwired in, and we have now replaced all the network cables and replaced the router with a brand new one. Netflix and internet works just fine on all other devices (laptops, netbooks, Bluray streaming). Our download speed is also perfectly fine on all other devices.
When running the connection tests sometimes it's perfectly fine, sometimes it throws a NAT error (we have put the Xbox IP into the DMZ so that eliminates the NAT issue), now it's throwing an ICMP error. It seems to come and go with no consistency.
Our settings are as follows:
Connection ADSL: 6MBdown/800KB up
Core Switch: ASUS GX-D1081 8-port GB switch
XBOX Switch: TP-Link TL-WR1043ND Gigabit Wirelesss N Router
Xbox connection: Wired, Static IP.
Router config: NAT Firewall, port 3074 forwarded to XBox.
