May have fixed my sleep issue with a router firmware update
 
    
        
                
            
                
                    Just a note to let everyone know that I think I resolved my Twine's sleep issues. I was having issues similar to what others have posted.
I use a Cisco/Linksys E4200 WiFi router. It was running the out-of-the-box firmware from about 1 year (or more) ago, version 1.0.01. I upgraded the firmware to the latest and now the Twine seems to sleep and wake properly. 
I hope this info helps someone! 
Best, William

Generally we've found that Cisco/Linksys routers work very well. The E1200 is our favorite. http://www.amazon.com/gp/product/B004T9RR6I
