The following table describes the labels in this screen.

DESCRIPTION

QoS

Select the Enable check box to turn on QoS to improve your network

 

performance.

 

 

WAN Managed

Enter the amount of upstream bandwidth for the WAN interfaces that

Upstream

you want to allocate using QoS.

Bandwidth

The recommendation is to set this speed to match the interfaces’ actual

 

 

transmission speed. For example, set the WAN interfaces’ speed to

 

100000 kbps if your Internet connection has an upstream transmission

 

speed of 100 Mbps.

 

You can set this number higher than the interfaces’ 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 interfaces’ actual

 

transmission speed. This will cause the ZyXEL Device to not use some of

 

the interfaces’ available bandwidth.

 

If you leave this field blank, the ZyXEL Device automatically sets this

 

number to be 95% of the WAN interfaces’ actual upstream transmission

 

speed.

 

 

LAN Managed

Enter the amount of downstream bandwidth for the LAN interfaces

Downstream

(including WLAN) that you want to allocate using QoS.

Bandwidth

The recommendation is to set this speed to match the WAN interfaces’

 

 

actual transmission speed. For example, set the LAN managed

 

downstream bandwidth to 100000 kbps if you use a 100 Mbps wired

 

Ethernet WAN connection.

 

You can also set this number lower than the WAN interfaces’ actual

 

transmission speed. This will cause the ZyXEL Device to not use some of

 

the interfaces’ available bandwidth.

 

If you leave this field blank, the ZyXEL Device automatically sets this to

 

the LAN interfaces’ maximum supported connection speed.
