DESCRIPTION
QoS
Select the Enable check box to turn on QoS to improve your network 
performance. 
WAN Managed 
Upstream 
Bandwidth 
Enter the amount of upstream bandwidth for the WAN interfaces that 
you want to allocate using QoS. 
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 
Downstream 
Bandwidth 
Enter the amount of downstream bandwidth for the LAN interfaces 
(including HPNA and WLAN) that you want to allocate using QoS. 
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.
