Hi I have been having this problem for a few weeks, my computer at work is connected to a Network. I use CAM software called Radan, when I was using this software the Network connection went slow. The packet data being sent shot up sky high and it wasn't receiving any. I could overcome this by just exiting the application and re-opening. The computer then disconnected from the network without even opening any applications and the packets sent were high and none being received again. I decided to put a network card in a PCI slot to try it and this solved the problem, but now I keep losing my mouse connection, it just stops working, if i take the mouse connection out and put it back in again it works for a few minutes then stops? If i restart the computer the mouse isn't working. Does anyone have any ideas? Thanks -- Ian
