After my laptop comes out of hibernate, the wireless connection does not work. In fact, it can't see any of the 7 available wireless networks in my area, nevermind the one it was connected to when it went into hibernate mode.

I run /etc/init.d/dbus restart but that does not fix it. It's still unable to see any of the wireless networks in the area. I have to restart the machine for wireless to work again.

Please help me find a solution to this.
