For around 2 weeks now I've had a weird disconnect issue. Every now and then I'm just kicked out of Live with no warning (no prior lag or anything). The weirdest part? I can solve it by unplugging the ethernet cable from the console and plugging it back so no modem/router reboots needed. It's nothing really major and only occurs once every three to four hours, but it's annoying and it's messed up co-op games already. And surely it's not normal since it only just started happening. What could the problem be?
