Hi,
I have an inspirion 1545 with Vista. Two days ago my internet stopped working all of a sudden, the laptop can pick up the available network but does not connect, I have reinstalled all the necessary software and have tried downloading the driver Intel(r) wifi 5100 several times which the laptop unzips but does not seem to run and is not found in the network adaptor section in device manager. I have reloaded all the drivers in the order given on various posts on this site but still no joy. I cannot seem to find where the computer downloaded the Intel(r) wifi5100 to. Can anyone help I am getting extremely frustrated????
