Cause

SmartByte may contribute to a reduced overall network speed in specific circumstances. This is a normal situation as SmartByte allocates a small percentage of the available network bandwidth to its own operation. There may be other contributing factors to account for measured speeds below what your ISP provides on average.

Resolution

If network performance has not improved after performing these steps and switching SmartByte off, then the issue is not associated with SmartByte.
