Any idea why my Thunderbolt, which had previously been working fine, now switches to 3G when it goes into standby (screen goes dark) from wifi. When I wake it back up it then reestablishes a wifi connection, however, there is a data delay while it reestablishes the wifi connection and I have to wait before I can do anything.
Is there a setting somewhere for it to keep the wifi connection while in standby mode?
Thanks.
