8 If you are connecting an Ethernet cable to the WAN port for Ethernet WAN connections, and an RJ-11
cable to the DSL port for DSL connections at the same time. Make sure you have the Ethernet WAN port
connected to a MODEM or Router that has Internet access. If it does not, remove the Ethernet cable or
restore the fourth LAN port back from a WAN port to a LAN port.
The Ethernet WAN connection has priority over the DSL connection. The Zyxel Device follows this rule,
even the Ethernet WAN port doesn’t have an IP for Internet connections.
9 If the problem continues, contact your ISP.
I cannot access the Internet through a DSL connection.
1 Make sure you have the DSL WAN port connected to a telephone jack (or the DSL or modem jack on a
splitter if you have one).
2 Make sure you configured a proper DSL WAN interface (Network Setting > Broadband screen) with the
Internet account information provided by your ISP and that it is enabled.
3 Check that the LAN interface you are connected to is in the same interface group as the DSL
connection (Network Setting > Interface Grouping).
4 If you set up a WAN connection using bridging service, make sure you turn off the DHCP feature in the
LAN screen to have the clients get WAN IP addresses directly from your ISP’s DHCP server.
I cannot connect to the Internet using a second DSL connection.
ADSL and VDSL connections cannot work at the same time. You can only use one type of DSL
connection, either ADSL or VDSL connection at one time.

1 Make sure you have the Ethernet WAN port connected to a Modem or Router.
2 Make sure you configured a proper Ethernet WAN interface (Network Setting > Broadband screen) with
the Internet account information provided by your ISP and that it is enabled.
3 Check that the WAN interface you are connected to is in the same interface group as the Ethernet
connection (Network Setting > Interface Group).
4 If you set up a WAN connection using bridging service, make sure you turn off the DHCP feature in the
