I've got a Wireless card (Intel Centrino Advanced-N 6200 AGN) in my Laptop (HP EliteBook 2740p), and from time to time, I lose all wireless network connectivity with the only option to get it back being deactivating and reactivating the network adapter or rebooting the computer. I'm using Windows 7 Pro SP1 64 bit. and the Wifi drivers are up to date.
Any idea?
