Click Start–>Run–>type “gpedit.msc” without the ”
• This opens the group policy editor. Then go to
  Local Computer Policy–>Computer Configuration–>Administrative Templates–>
  Network–>QOS Packet Scheduler–>Limit Reservable Bandwidth
• Double click on Limit Reservable bandwidth. It will
  say it is not configured, but the truth is under the
  ‘Explain’ tab :
  “By default, the Packet Scheduler limits the system to
  20 percent of the bandwidth of a connection, but you
  can use this setting to override the default.”

  than the default 20%.
