DESCRIPTION
Select the check box to turn on QoS to improve your network
performance.
Enter the amount of upstream bandwidth for the WAN interface that you
want to allocate using QoS.
The recommendation is to set this speed to match the interface's actual
transmission speed. For example, set the WAN interface speed to
100000 kbps if your Internet connection has an upstream transmission
speed of 100 Mbps.
You can set this number higher than the interface's actual transmission
speed. The ZyXEL Device uses up to 95% of the DSL port's actual
upstream transmission speed even if you set this number higher than
the DSL port's actual transmission speed.
You can also set this number lower than the interface's actual
transmission speed. This will cause the ZyXEL Device to not use some of
the interface's available bandwidth.
If you leave this field blank, the ZyXEL Device automatically sets this
number to be 95% of the DSL port's actual upstream transmission
speed.
Click Apply to save your changes back to the ZyXEL Device.
