Problem with wireless card

I'm having the same problem with my card Wifi MacBook Pro 17 Home 2011.

In my case, when I start my Mac it detects the card then no longer detects. Open my MAC, removing plaque, cleaning the contacts with cotton and just putting the lid.

The only problem I'm having now and occasionally I get no signal and I have to restart the mac to re-use the internt.
