Just a heads up in case someone runs into the same problem. Since yesterday I could NOT connect the phone to my D-Link DIR-615 wireless router. No matter what I tried, it would say connecting, obtaining IP address before failing. Found the solution in a thread for the 'other' S2. In the router itself, under Setup\Wireless Settings\WPA choose as cypher type "AES ONLY". Mine was on the option "TKIP or AES" and would not let me connect. Changed it to AES only, rebooted the router and for the first time in 2 days was able to connect. So far so good!!!! Hope this helps someone.
