Connecting a Mac to broadband
with the D-Link DSL-210 modem
Author: Denis Bredelet
There are few USB ADSL modems compatible with the Mac. As it turns out,
the DSL-210 is compatible, but the D-Link support line will never let
you hear so. Also I could not find any documentation related to the
This is my experience on how to connect the modem to BSNL broadband
(India) using a PowerBook G4. The operating system is MacOS X 10.3.9
but it should be pretty much the same with MacOS 9 or Linux.
First, install the drivers from the CD that come with the modem. Do not
connect the modem before installing. The drivers are kept in the
Driver/MAC Driver/MAC-OS X folder on the CD. Uncompressing the files
create a folder called
Release which contain the installer. Follow the
instructions to install the driver.
After the computer finished rebooting, you can connect the modem to the
computer. You should see the "USB link" light become immediately green.
After some time, the "ADSL link" light will start blinking, which shows
that the driver is properly installed.
If the modem is connected to your ADSL line, the light will become
steady. That means an ADSL connection is established. The installation
is not finished though! You still need to enter your account details.
Modem configuration page
System Preferences and go to the Network Preferences pane. MacOS X will
inform you that it detected a new network port; accept it. On my
computer the port is called "Ethernet Adaptor (en2)". Make sure that
the modem is connected and select "Ethernet Adaptor (en2)" in the list.
Press Configure. IMPORTANT: do not run the assistant (Assist Me).
Select the PPPoE tab. Ensure that "Connect using PPPoE" is unchecked.
Go to the TCP/IP tab and select "Using DHCP". Leave the other fields
blank. Press Apply to validate the changes.
Now start your favorite web browser (eg. Safari) and type the following
in the address bar:
You should be prompted for a user name and a password. Enter the

the menu on the left of the modem configuration page, select "Misc
Configuration". Set the access to "Restricted" and "LAN". In the left
menu select "WAN" (Configuration section).
Enable Virtual Circuit.
Choose PPPoE-LLC for the Encapsulation.
Disable DHCP. (with my modem the DHCP setting doesn't work)
In the Static IP address field, remove all contents.
Enter the username and password provided by BSNL broadband in the
Set the Disconnect Timeout to zero.
Enable Auto Reconnect.
Submit your changes then click on the link at the bottom of the page to
save the changes in the modem memory. Click on "Save & Reboot".
Connecting to the Internet
some time, the modem will be ready again. Go back to the Quick Start
page and click on "Connect". You can also check "Always On" so that you
don't have to load the welcome page to connect to the Internet next
The page should refresh and display "Connected".
Congratulations! You are now on the Internet.
Problems and solutions
I cannot open the modem configuration page
In Network Preferences, open the TCP/IP tab and check that DHCP is
selected. The IP address should be 10.0.0.3 and the router address
should be 10.0.0.2.
The modem indicates "Connected", yet I cannot use Internet
Make sure that the Static IP address contains 0.0.0.0 in the WAN
configuration. If that is not the case, empty the Static IP address
field and save the changes.
There is some incompatibility between the modem and Apple VPN
implementation. After connecting to a private network using VPN, the
general Internet becomes inaccessible.
I do not know a solution for that problem other than disconnecting and
reconnecting to the private network as needed.
