hows your NIC's. ( network interface card).....

or maybe you can use this tool to optimize TCP settings on that slow computers. this is useful:

have you tried using a known good network cable? basin cable na gyud guba.. check pod ang connectors basin hugaw or lu-ag.Â* if ok ang cable and connections, try disabling firewall if that helps.

also try these:
* Try updating the NIC drivers.
* In Device Manager,Right click the NIC adapter, select properties, if power management tab available., then click to uncheck theÂ* option to allow windows to turn of the device for power save..
* Try Reseating the NIC card or also try to plug it in different slot

other question, do you still have internet connectivity while you get the pop up message?

one most unlikely cause: bad power supply. if your power supply is not stable, it might cause the NIC to reset.. and windows will display that message when the NIC resets.
