Movistar-Observa-Telecom-RTA01NModem-router provided by Movistar. It’s a basic ADSL-modem with Wifi-option although there are no antennas.

The device has only one LAN-port so if you have to attach more devices by cable you need a switch to share the connection.


On top panel there are 6 lights and when your internet connection is established Power, Ethernet/Wifi, ADSL and Internet lights should be blinking green.


On the back panel you can turn the device on/off and disable or enable the Wifi or reset the device (by pressing the reset-button 10 seconds with sharp object).


How to access the modem

  1. Attach a cable from yellow LAN port on the router to the LAN port on your computer.
  2. Open your Internet browser and enter “” in the address bar. Press “Enter.”
  3. Enter the user name and password for the router. If you haven’t changed these settings previously username is: 1234 and password is: 1234.

On right top corner you can change the language from Español to English.


Internet connection setup (if another provider than Movistar)

If you have a Movistar connection there’s no need to do any modifications because the Movistar configuration is already preinstalled.

The connection configuration depends of your internet provider and you must have the necessary information to be able to configurate modem correctly. (More help here: Configuration data of Spanish broadband providers)

What you need to know is:

  • Modulation mode of ADSL (usually automatic)
  • Connection protocol (Dynamic IP, Static IP, PPPoE, PPPoA)
  • Encapsulation (VC-MUX, LLC)
  • Username and password (usually only within PPPoE and PPPoA connections)

First you want to choose the Advanced-mode on top right corner.

Setup -> WAN


If your connection (for example Orange) uses 8/32 on VPI/VCI, you have to delete the default Movistar connection before it’s possible to add a new one. Click the trashcan on right side of the page.


Otherwise you’ll receive an error message.


Wireless Network Setup

WLAN -> Basic

On SSID you can write your own network name or you can leave it as it is.


On “Security”-page you can change the default Wifi password as it’s probably a tricky one with lots of numbers and letters combined.

  • Security should be at least WPA (preferably WPA2). DO NOT use WEP!
  • PSK String is your password for the wireless network. It should have at least 8 letters or numbers combined.


After changes have been made and you clicked “Apply changes” the device reboots the Wifi.


Setup Wifi network (Advanced mode)

Setup -> WLAN -> Basic

On this page you can name your wireless network, change the channel (in case there’s another Wifi-network using the same frequency) and also change the transmit power of your wifi-network.


Add a secondary wireless network (Advanced mode)

Setup -> WLAN -> MBSSID

With this device it’s possible to add a another wireless network to be used as a secondary network with a simple password that is easy to insert on phones of your friends.


Set the password on “Security” -page: choose correct Wifi (Root, VAP0, VAP1, etc) and Encryption (preferably WPA2) and fill in the password.


Change the default password (Advanced mode)

Maintenance -> Password

You should change the default password to prevent anyone else accessing your modem.

First click and select user “1234” on “User Account Table” (bottom half of the page) and then fill the old password (by default: 1234) , then twice the new password and finally click “Modify”.


Change the ADSL modulation (Advanced mode)

Setup -> WAN -> ADSL

In some rare occasions Movistar still uses other than ADSL2+ -modulation and this means that the modulation has to be changed before the modem “finds” the ADSL signal.

Movistar uses G.Dmt or/and T1.413 (maximum download rate is 8 Mbit/s and upload 1 Mbit/s. With ADSL2+ max. download rate is 24 Mbit/s and upload 1 Mbit/s)


Status (Advanced mode)

On Advanced-mode: This page tells you if the connection is working. the speed of it and your connection IP-addresses (blurred).


Virtual Server and port forwarding

NAT -> Virtual Server

Port forwarding allows remote computers (for example, computers on the internet) to connect to a specific computer or service within a private local-area network (LAN). To use remote port forwarding, the address of the destination server and two port numbers must be known. The port numbers chosen depend on what application are to be used.

You also have to set up a static IP address to your device (computer, PS3, Xbox etc) to be able to use port forwarding.


VoIP and ALG (Advanced mode)

Advanced -> NAT -> ALG

If you’re having VoIP solution (other than Skype) and it’s giving problems you might want to disable some VoIP-related configurations. With some modems and VoIP providers ALG must be enabled and in some cases disabled, so you just have to try and see how it works in your case.

Depending what protocol your VoIP solution is using you must disable SIP or/and H.323 as they’re both enabled by default.
