When I turn on my console it immediately connects to Xbox Live no problems. Its when i play a game that the issue arises.
One of three things will happen. Either I will disconnect from XBL during the game's loading screen, I will disconnect during the matchmaking, or I will join a game and be disconnected within a couple of minutes. I have tried this with a number of different online games and they all yield the same result.
After I disconnect I run the network test and it says everything is fine. I try to reconnect immediately and it says it can't. 9 times out of 10 I have to restart the console just to reconnect to XBL. Upon a restart it immediately reconnects and starts the process over again.
I have tried all the usual solutions, even bypassing my router and plugging straight into my modem and this hasn't changed anything. No other device on my network has any problems with internet connection. Everything had been working fine for the previous 6 months, it has only been the last two or so weeks that I have been having this problem.
Here's some info:
What Country/State/Province do you live in? Australia
Modem brand & model number: Linksys WAG320N
Router brand & model number: N/A
Is UPnP Enabled? Yes
Do you have a NAT error? If so, what is your NAT? No, its set to Open

Who is your ISP(Internet Service Provider)? Iprimus
After you run "Test Xbox LIVE connection" press “Y” for "More Info”. In the pop-up that appears, what are the following values, if shown?
A: 192.168.1.100 / 255.255.255.0
D: 18.104.22.168 / 22.214.171.124
Thanks in advance
