What browsers are you guys using? For IE 8 or 9, try this in compatibiliy mode?
This happen on any other browsers like Opera, FF, Chrome, Safari?
Can anyone capture this process in detail and also use FF and firebug plugin to see if there is any info here?
I timed one of my routers last night, logged in, browsed a few pages then let it sit with out touching anything and it log out at about 3 minute. There could be a mouse click process going on here too.
