keep loosing connection with live while playing

If that doesn't help buy a Wireless Adapter. I have an XBOX 360 Without WiFi built in so I use an adapter. If you wire your internet it will use your bandwidth like crazy which will make your internet stop for a moment and log you off XBOX Live then it may
connect back and they it may leave you offline for hours then go on again after the day is gone. So my advice is buy an adapter. You can get them for about 5-10 bucks online. I actually never knew they were this expensive but here is where you can find the
cheapest. Trust me it will help.

Your other answer is to buy a new xbox with wireless built in which costs $149.99 at stores like thrift shops or pawn shops.

you on talk talk lol, i sign out when im at the ops 2 mp menu then sign back in, seems to do the trick

Unfortunately it is probably more to do with what the previous poster indicated that a reboot on the router could help. It wouldn't hurt to reboot your computer as well.

Playing on PC I imagine?

Also, possibly try resetting your router/modem.

Generally this only happens when the console looses net connectivity while powered off... if it looses network connection--even for a second--it get kicked off LIVE and then shut down.
