I cannot access the Internet.

Check the hardware connections, and make sure the LEDs are behaving as expected. See the 
Quick Start Guide and 

Make sure you entered your ISP account information correctly in the Network Setting > 
Broadband screen. These fields are case-sensitive, so make sure [Caps Lock] is not on. 

If you are trying to access the Internet wirelessly, make sure that you enabled the wireless LAN in 
the Device and your wireless client and that the wireless settings in the wireless client are the same 
as the settings in the Device.

Disconnect all the cables from your device and reconnect them. 

If the problem continues, contact your ISP. 

I cannot access the Internet through a DSL connection.

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).

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.

Check that the LAN interface you are connected to is in the same interface group as the DSL 
connection (Network Setting > Interface Group).

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.

I cannot access the Internet anymore. I had access to the Internet (with the Device), but my 

Internet connection is not available anymore.

Your session with the Device may have expired. Try logging into the Device again.
