Being Logged Off Every Few Mins Even When Active?

Is anyone else having this problem or know a fix for it? Im not sure if this is sl side or mine but any suggestions would be useful.

I can log into SL just fine and start to play but in the middle of doing something I get logged out. This generally happens every 10-25 mins in general. This does not happen with another internet based mmo game I play.

Now Heres My Settings:
1.5 DSL connection to the net
Brand new linksys router wired to the pc i use for sl. But has wireless capabilities my laptop uses for my work.
Windows XP
512 ram (yes I need more I know)
AMD Athlon 2.20 GHz
NVidia GeForce FX 5500

Cat - is this a case of everything working fine until you get an explicit message saying you are being logged out - OR - does it fail silently. with no error message, but you can't mover around (other than turning)?

It goes 'ding' and says You have been logged out. And the screen goes grey.

Then we can probably rule out networking problems.

If this was only hapenning yesterday it may have been due to a grid-wide upgrade that was taking place.

Otherwise, I would email support, citing the specific time of 3 or 4 recent occurences - it sounds as though you were actively or purposefully logged out - and they may be able to track the reason down for you.
