At the time of writing, December 2017, the currently shipping hardware version of the DLink DSL-320B modem/router is the DSL-320B-

*AAISP ships these devices for use as straight ethernet modems. Although they are capable of working as (buggy) routers, AA pre-configures them to work in bridge mode only, that is, in simple PPPoE modem-only mode, not operating as routers.
The modem’s admin web interface is quite insecure and in ‘router’ mode they have various critical security bugs, which is why we strongly suggest that customers never use them configured in ‘router’ mode. They are sold by AAISP as bridge-only. Older pre-Z1 modems, such as the now obsolete “-D1” model, were shipped with their reset buttons covered to protect them and prevent them from being reset!

*The modems support the ADSL standards G.992.1/G.DMT (‘ADSL1’), G.992.3 (ADSL2) and G.992.5 (ADSL2+) and can either auto-detect the best mode or lock it to just one option. Annex M is supported. SRA is also supported.
*VDSL2 is not supported, so these devices cannot be used with FTTC.
*TR-069 is not supported by AA on these devices, so they cannot automatically be remotely configured, monitored or upgraded by AA.

== After each reset to factory settings ==
<p id="post-factory-reset">
After any reset to factory settings you will need to make the following change using the web admin user interface in order to get the device to work properly as a straight modem. (Factory default <code><nowiki>http://192.168.1.1</nowiki></code>, and your own ip address set to something suitable in that same /24 subnet, username=admin, password=admin.)
Go to “Setup” and “ADSL Setup” and there tick “Manual Setup”. Then tick “Bridge Mode”. The “Connection Type” should show “1483 Bridged IP LLC" and the VPI / VCI settings on that page should be set to VPI = 0, VCI = 38. See also article at [http://www.dlink.com/uk/en/support/faq/modems/dsl-modems/dsl_320b/how-to-setup-dsl-320b-revision-z1-in-bridge-mode bridge mode setup article at Dlink website].
If your modem is accessible by users on the LAN, see the notes on security and access given earlier. Ideally consider using your router’s firewall capabilities if possible to block access to the modem. Failing that upgrade the firmware - see earlier notes - and set a suitable administrative password (see the Maintenance menu).
Following this you will then also need to make the configuration changes described in the previous section.
To reset the modem to factory settings, locate the reset button hole on the rear panel of the unit. With the modem powered on, use a paperclip to hold the button down and keep an eye on the status LED on the front of the unit. When the status LED goes off release the reset button and the modem will go through its reboot process.
Wait about 30 seconds to access the modem. The default IPv4 address for the modem’s http admin user interface on the LAN is 192.168.1.1/24. Your own IPv4 address will need to be in the same subnet and different from that of the modem,
