Okay so I have seen a bunch of other posts regarding issues similar to this, and my issue is still not fixed. This has been happening for a couple months now. It seems everytime I play an online game now, my xbox get randomly disconnected from the Xbox LIVE service. Then when I go back to dashboard Xbox LIVE magically appears to be back and working. Sometimes I do get the 8015190B error code although it has not appeared for a while now. This disconnection can happen randomly from 5-30 minutes of playing an online game. I have a wired connection and a xbox 360 slim.
I have also tried the solution of deleting your profile, deleting your cache 3 times and then redownloading your profile, but that hasn't changed a thing. It also appears to have nothing to do with my router as my pc is connected aswell and internet service is also available even when my xbox gets disconnected.
I would appreciate any response as I am unimpressed that there is this many people having similar issues and still have no solutions.
