I have a BT voyager 1060 network card. It was all working well, but I then removed the card when the laptop was off to install a memory card. I then turned on to see if all was OK with the new memory but forgot to put the network card back in. I turned off and inserted it in, turned back on but the laptop does not recognise the card and the lights on the card do not come on. So I tried to reinstall the card, but this did not help.
