Teltonika RUT240/241 Modem REcovery

Restore Your Cellular Modem Connection

Following a cellular-network outage, some RUT240/241 modems may remain unable to reconnect even after service has been restored. This procedure clears the file preventing another connection attempt and restarts the modem.

You must be near the modem. Your phone, tablet, or computer needs to connect directly to the modem’s Wi-Fi. Keep the modem powered on throughout the procedure.

Before you begin

  • Have a phone, tablet, or computer with Wi-Fi and a web browser.
  • Have the modem Wi-Fi and administrator passwords supplied with your modem. If you do not have them, contact Atlantis Technologies.
  • Allow approximately 10 minutes to complete the procedure and verify the connection.

1. Connect to the modem

  1. Open your device’s Wi-Fi settings and connect to Atlantis_RUT241_XXXX. The final characters identify your modem.
  2. Enter the modem Wi-Fi password supplied with the unit.
  3. Open Safari, Chrome, or another web browser.
  4. Enter http://10.0.100.7 in the browser’s address bar.
  5. Sign in with username admin and the administrator password supplied with the modem.
If your browser warns that the connection is not private, confirm that the address is exactly 10.0.100.7 and continue to the local modem page. This page is provided directly by the modem, not through the internet.

2. Find the Modem debug section

The modem interface can look different depending on its firmware and the device you are using. Choose the example that most closely matches your screen.

Newer desktop or tablet layout

Select System → Maintenance → Troubleshoot. Scroll past Diagnostics to the Modem debug section.

  1. Tap or click the AT command field under Modem debug.
  2. Copy and paste the command below exactly as shown.

iPhone users: use straight quotation marks. Command #1 requires the straight vertical mark “, not the curly marks “ or ”. If typing the command manually, press and hold the quotation-mark key and select the straight vertical quotation mark. Copying the command above is recommended.
  1. Select Send.
  2. Wait for the response. A successful response normally ends with OK.

4. Run Command #2 and restart

  1. Replace the first command with the command below.

Command #2

AT+CFUN=1,1
  1. Select Send.
  2. Wait several minutes while the modem restarts. The modem page may temporarily stop responding, and your device may briefly disconnect from the modem Wi-Fi.
  3. If necessary, reconnect to the modem Wi-Fi before continuing.
Use the Send button for both commands. Do not select Save & Apply.

5. Confirm that the modem is connected

  1. Return to the modem page at http://10.0.100.7.
  2. Go to Status → Overview.
  3. Select the information (i) icon beside INTERNAL MODEM.
  4. Find Data connection state.
  5. Allow a few minutes for the state to change to Connected.

If the modem does not reconnect

  • Confirm that Command #1 used straight quotation marks and contained no extra spaces.
  • Confirm that the response to each command ended with OK.
  • Wait up to 10 minutes, refresh Status → Overview, and check the data connection again.
  • If the modem still does not show Connected, contact Atlantis Technologies. You may also return the modem to us and we will perform the procedure.
