I'm having the same problem. I don't normally leave the computer on to go into standby, just shut it down. Later when I turn the laptop back on, it can't connect to wireless, doesn't see the SSID broadcast, and can't connect with already setup profile.
After I powercycle the WBR-1310, the laptop connects on it's own, and it can see the network in the available networks view.
I tried using a wireless sniffer, it doesn't even show the DLink wireless signal, its like the wireless portion is completely turned off.
