Select the check box to turn on QoS to improve your network performance.

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 XMG 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 XMG to not use some of the interfaces' available bandwidth.
If you leave this field blank, the XMG automatically sets this number to be 95% of the WAN
interfaces' actual upstream transmission speed.
Enter the amount of downstream bandwidth for the LAN interfaces (including 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 XMG to not use some of the interfaces' available bandwidth.
If you leave this field blank, the XMG automatically sets this to the LAN interfaces' maximum
supported connection speed.
Select how the XMG assigns priorities to various upstream traffic flows.
• Disables auto priority mapping and has the XMG put packets into the queues
No ne :
according to your classification rules. Traffic which does not match any of the classification
rules is mapped into the default queue with the lowest priority.
• Automatically assign priority based on the IEEE 802.1p priority level.
Ethe rne t Prio rity:
• Automatically assign priority based on the first three bits of the TOS field in the
IP Pre c e de nc e :
IP header.
• Automatically assign priority based on the packet size. Smaller packets get
Pa c ke t L e ng th:
higher priority since control, signaling, VoIP, internet gaming, or other real-time packets are
usually small while larger packets are usually best effort data packets like file transfers.
