Under Line 1 there is an option called Jitter Buffer Level, depending on your internet speed you want to adjust that accordingly.

3mbps and below :: Very to Extremely High
4mbps and above :: High or Low

Rule of thumb is the FASTER your internet speed, the LOWER you want this level, and vice versa with lower speeds, the LOWER the speed, the HIGHER you want the Jitter level.
