Check the power management settings of the wireless card and make sure it is not set to turn off to save power.

Next, try uninstalling the card and installing the same or updated wireless driver.

If neither of these work, consider trying another wireless card.

I'd guess (as John said) that the WLAN card is configured to use power-save mode.  In the driver advanced properties you can check this.  Try setting it to CAM (constantly-awake mode) if the option is there.
