SmartRG SR505N - ADSL/ADSL2+ Routed Mode Configuration

Although the SmartRG 505N modem is primarily supplied for VDSL services, some ADSL users  may opt to use it as well. There are a couple of extra steps we will have to take to get it working with ADSL services though, as these modems are defaulted to VDSL settings.

    1. Open a web browser (Internet Explorer, Firefox, Safari, Etc.) and go to the address  http://192.168.1.1
    2. Click on the "Advanced Configuration" link, this should be located in the top right corner of the page.
    3. You should now be prompted for a password. By default the username is admin and the password is also admin.
    4. As we are using ADSL we will now need to remove the default VDSL WAN Service. To do this go to Advanced Setup -> WAN Service, then check the "Remove" box and press the "Remove" button.

    1. Next, click on Advanced Setup -> Layer 2 Interface -> PTM Interface. Once again check the "Remove" check box then press the "Remove" button.



  1. Now go to Advanced Setup -> Layer 2 Interface -> ATM Interface and click the "Add" button.
    IMPORTANT: Though similar in name, this is NOT the same page as in step 5. (PTM vs. ATM)
  2. Fill out the ATM PVC Configuration form as follows:
    MAKE SURE YOU CHECK THE "Path1 (Interleaved)" BOX, IT WILL BY UNCHECKED BY DDEFAULT WHICH MAY LEAD TO CONNECTION ISSUES
  3. Click apply/save.
  4. Next we will need to create the WAN service for the ATM interface that we just created. To do this go to Advanced Setup -> WAN Service.
  5. Click the "Add" button.
  6. The "WAN Service Interface Configuration page should now show up. On this page there will be a drop down box, set this the the available atm interface and click "Next".
  7. Now we will find ourselves at the "WAN Service Configuration" page. You may select one of two options here based on your preferences:
    • PPP over Ethernet (PPPoE) - When using this service type, the modem will authenticate itself and will perform routing funtions. You should use this if you only intend to use the modem along with your devices.
    • Bridging - When using this service type, the modem will NOT authenticate itself, will NOT perform routing functions (including WIFI), and will REQUIRE a separate device to log you into our service. You should use this if you intend to use a dedicated router along with your modem and other devices.
  8. Further down on the WAN Service Configuration page you should see 802.1p priority, set this to -1. You should also see the 802.1q VLAN ID, set this to -1.
  9. Click next.
  10. If you've selected Bridging for your connection type, proceed to step 16. Otherwise you should find yourself at the PPP Username and Password page. Enter your PPP Username and PPP Password into the relevant fields.

    NOTE: This username and password would have been chosen when you signed up for our service. If you do not remember your username or password, please contact us for support
  11. Ensure that "Retry PPP password on authentication error", "Enable Firewall", and "Enable NAT" are all checked, then click Next.
  12. The following two pages (Routing -- Default Gateway, and DNS Server Configuration) can be left as is, press next on both of these pages.
  13. Great news, we are almost done! You should now find yourself at the "WAN Setup - Summary" page. If the information listed here is correct click on "Apply/Save".
  14. If you've setup your SmartRG modem in PPPoE mode you should now be online! If you selected Bridged mode please attach and configure your router, or follow one of these useful guides on how to create a dialer on your PC!
