Line Speed
To declare correct line speed of uploading and downloading for each WAN interface can let the
device operate its QoS&BWM and WAN Load Balance functions normally.
If you don't know accurate line speed of your subscribed Internet service, following are some
suggestions:
 High Speed Ethernet WAN: Upload 100Mbps, Download 100Mbps;
 Gigabit Ethernet WAN: Upload 1000Mbps, Download 1000Mbps;
 CAT4 Built‐in LTE Module: Upload 50Mbps, Download 150Mbps;
 CAT3 LTE USB Dongle: Upload 50Mbps, Download 100Mbps;
 3G USB Dongle: Upload 5Mbps, Download 21Mbps;
 ADSL2+: Upload 2Mbps, Download 22Mbps.

VLAN Tagging
Sometimes, your ISP required a VLAN tag to be inserted into the WAN packets from Gateway for
specific services. Ensure to specify it in the WAN physical interface. Please be noted that only Ethernet
and ADSL physical interfaces support the feature.
As an example (just for an example, your device may not have an ADSL WAN), you can setup
WAN‐1 without VLAN Tagging by using Ethernet WAN interface for your Intranet to access the Internet.
Index skipping is used to reserve slots for new function insertion, when required.
