Interface
name Configured when the DNS type is se-
lected as the interface. After the config-
uration, the router uses the DNS ob-
tained by the interface associated with
the DNS. Therefore, you need to pay
special attention to whether the inter-
face can obtain DNS.
Dropdown List
⚫
modem
⚫
eth1
⚫
eth0
Eth0 indicates that the associated WAN
port uses PPPoE dialup or DHCP to obtain
DNS. Pay special attention to the eth0 is
invalid when the WAN is a static IP ad-
dress. If the PPP dialing configuration dis-
ables the peer DNS, the modem is inva-
lid. eth1 indicates the DNS obtained by
the WLAN.
Step 4 Single click “ save ” to complete the configuration of “ Network Type “ .
When the "default route" selects the "eth0" interface and the WAN port is switched from DHCP or static IP
to PPPoE, the default route of the router needs to click "Save" on the

fect and display.

5.2.7 Link Backup
The H8922 4G Routers implement the multi-network link backup function in combination with the actual needs
of the customer. They can implement mutual backup between wireless and wireless, wireless and wired links,
and can quickly switch to backup when a link fails. The link ensures the connectivity and stability of the commu-
nication link of the lower computer, thus ensuring that the data service of the user is not affected. H8922 4G
Router supports both cold and hot backup modes. The advantage of hot backup is that it can communicate
directly after link switching. However, the disadvantage is that communication costs will be generated when
the backup link is online in real time, which increases the cost.
