I'm not sure if it's the nearest tower, or the tower with the strongest signal (9 times out of 10, that's going to be the one closest to you.)
I don't know of a way to force it to lock onto one tower over another.
I can suggest that you go into Connection Manager, toggle the radio off and back on and see if it makes your connection JUMP to another tower. It's a crap shoot, but that's all I can offer.
