Before you start configuring the SmartRG SR505n, there are 4 things to check:
- Firmware CheckThat you're using the same firmware used in writing these instructions.
- Factory Settings This is the procedure NCF uses to configure a SmartRG SR505N modem out of the box or after a factory reset. To learn more about configuring your particular modem, consult the manual. NOTE: If the modem is brand new, "user name: admin and password admin" will gain access. If the modem is not new, it is recommended to reset the modem to the factory defaults by holding down the reset button with a paper clip for ~10 seconds.

Configure as Bridge
Do this only if you prefer to use your own external router rather than the one built into your SmartRG unit.

- If the modem is fresh from the factory, use the default user name and password to gain access
- user: admin
- password: admin
If the modem was previously configured for someone, the password would be the previous user's DSL password. If it is unknown then do a reset to factory default, using a paper-clip in the reset hole on the back. Hold for 6 to 9 seconds to reset. The user name and password will now be as above.

Upgrading the Firmware
We recommend that you only do firmware update over an ethernet connection and NOT via wifi. Also DO NOT power off the modem in the middle of a firmware update
The current firmware available to the NCF Office is 220.127.116.11. You can verify your firmware by checking the software version on the Device Info page. To request a copy of this firmware email [email@example.com].
To install this new firmware onto your modem perform the following steps:
- Download the firmware file and save it to a location on your computer that you can find easily.
- Open a web browser and go to the address http://192.168.1.1
- Select Manage Gateway (Advanced) and log in (by default the username is admin and password is your dsl password as shown in Getting Started above)
- Click on Management → Update Software
- Click on Choose File
- Upload the firmware file that you downloaded in step 1.
- Click Update Software
Note: the modem will reboot once the new firmware has been uploaded. This process may take up to 15 minutes to resync (DSL light returns to solid green) and reconnect (the internet light starts blinking again).
