BCM4311 Dropping Connection To Router

[l]

This wireless card will not remain connected to my router.  I am going to use this laptop as a ip camera security server.  

When it boots up I can connect to it via ssh for about 10 minutes or less and then it looses connection to the router.  

Router:

Netgear Rangemax Wireless-N 150

Hardware :

Compaq Presario C700
