Atheros/Lenovo Wireless A/B/G card roaming issues

I'm experiencing an issue with build 7000 and the wireless card. It won't connect to different wireless networks automatically after putting the machine into standby. example, use the corporate network at the office, close the lid, bring the laptop home open the lid (resume from standby) it attempts to reconnect to the corporate wireless and never recovers. i get the same experience when going into standby at the office and returning to the office.

Oh, driver is from Microsoft version 1.0.0.7 date: 11/7/08, manufacture of card indicates: Atheros Communications Inc.

yeah i had that already covered here...
