Lost 4G Service on TBolt; Only 3G?

I just purchased a used Thunderbolt to get me through the next couple of months until the iPhone 5 comes out.  I "upgraded" from my Droid X, which I loved, simply because I wanted to try the 4G and the X was just getting old and had quite a bit of lag. 

I like the Thunderbolt so far, but have a simple question.  The first night I had it, it was on 4G.  But that night before I went to bed I hit the "Enable power efficiency" button under the Power tab.  That said it would take it off 4G because of the batter drain, etc.  I have since turned this off because I wanted the 4G during the day.  However, I have not gotten any 4G service over the past two days.

Is there a reason the 4G is not coming on now?  I have restarted the phone, etc.

Thanks for the help.

Have you checked your network mode?  Settings > Wireless & networks > mobile networks > network mode

I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
