Step-by-Step Configuration Guide

Step 1: Export the Router Configuration File (config.xml)

1. Connect to your router interface:

   • Open your browser and navigate to http://192.168.1.1
2. Login with your admin username and password

3. Keep the admin dashboard open, then open a new tab and go to:

   • http://192.168.1.1/html/ssmp/cfgfile/cfgfile.asp

4. Enable hidden elements using your browser’s Developer Console:

   $('[style="display:none"]').removeAttr('style');
   

5. Click the download button to save the config.xml file to your computer.

Step 2: Disable TR-069 Remote Management

TR-069 is used by ISPs to remotely control your router. Disabling it gives you full privacy.

Modify the following in config.xml:

• Change:

  <EnableCWMP>1</EnableCWMP>
  

  To:

  <EnableCWMP>0</EnableCWMP>
  

• Change:

  <PeriodicInformEnable>1</PeriodicInformEnable>
  

  To:

  <PeriodicInformEnable>0</PeriodicInformEnable>
  

• Set the ACS (Auto Configuration Server) URL to a dummy:

  <URL>http://0.0.0.0:7777/dsl</URL>
  

• Replace credentials with dummy placeholders:

  <Username>xxxxxx</Username>
  <Password>xxxxxx</Password>
  

• Set all TR069FLAG values under WAN connections to 0

---

Step 3: Disable VOIP Services

If you’re not using VOIP, disabling it improves DSL performance and prevents VOIP reconfiguration by your ISP.

In the config.xml, make the following changes:

• Change all VoiceProfileInstance elements from:

  <Enable>Enabled</Enable>
  

  To:

  <Enable>Disabled</Enable>
  

• Disable both voice lines (usually InstanceID 1 and 2)

• Update SIP server addresses to local dummy values:

  <ProxyServer>127.0.0.1</ProxyServer>
  <RegistrarServer>127.0.0.1</RegistrarServer>
  <SIPPort>7777</SIPPort>
  

• Replace VOIP credentials:

  <AuthUserName>user@127.0.0.1</AuthUserName>
  <AuthPassword>xxxxxx</AuthPassword>
  

Result: No more VOIP interference, and router won’t attempt VOIP registration.

Step 4: Import the Edited Configuration File

Go to http://192.168.1.1/html/ssmp/cfgfile/cfgfile.asp in your browser, upload your edited config.xml file, and click “Update Configuration File” to save the changes.

Technical Notes

• DSL Internet remains fully functional
• VOIP features are completely disabled
• No remote ISP configuration possible
• Keep your modified config.xml private – don’t share it or upload it online!

Reverting the Changes

If you ever need to go back:

1. Simply reset the router using the physical RESET button.
2. This will restore factory settings, including TR-069 and VOIP features.
