An Internet connection issue (speed, signal detection, connectivity…) is often related to your FRITZ!Box modem or your Wi‑Fi network.
Follow these steps to identify and fix the problem :
1️⃣Check with the MyTango app :
- Open MyTango → Test Your Internet Connection
- Make sure your line is active and that Wi‑Fi is detected
- If everything seems correct but you still have no connection, proceed to the following steps
2️⃣Check your FRITZ!Box lights :
Power and WLAN lights should be on and steady
-
Case 1: Power and WLAN lights are on :
- Make sure you are connected to the correct Wi‑Fi network
- Test your connection with another device (computer, smartphone)
- If it works on the other device, your initial device may be defective
- Restart it and forget the Wi‑Fi network, then reconnect by entering the password again
-
Case 2: WLAN light is off :
- Wi‑Fi is not active
- Briefly press the WLAN button on your FRITZ!Box
- The light will blink and then stay steady when Wi‑Fi is activated
3️⃣Check your Ethernet cable connection :
- Unplug and replug your FRITZ!Box
- If you have a fiber box (ONT), unplug and replug it as well
- Make sure the Ethernet cable is properly connected to your FRITZ!Box and your computer
- Test if Internet works via cable:
- If it works, the issue is probably with the Wi‑Fi signal
- If it doesn’t, the issue is likely with your FRITZ!Box or Internet connection
4️⃣Disconnect and reconnect your devices to Wi‑Fi :
- On your device (computer, tablet, smartphone):
- Forget the Wi‑Fi network
- Reconnect by entering the password again
- Ensure you are connected to the correct Wi‑Fi network
5️⃣Check Wi‑Fi range and placement :
- Move your devices closer to the FRITZ!Box
- Avoid physical obstacles and nearby electronic devices
Tango tip: place the FRITZ!Box vertically for better signal coverage
6️⃣ Change Wi‑Fi channel :
- A congested Wi‑Fi channel can disrupt your signal
- To change the channel:
- Open a browser and enter fritz.box or 192.168.178.1
- Log in with the administrator password (found under your FRITZ!Box)
- Go to Wi‑Fi → Radio Channel
- Check the nearby networks and channel usage graph
- Select a less congested channel to improve your signal
7️⃣ Restart your devices :
- Restart your FRITZ!Box
- Turn off your devices (computer, tablet, smartphone) for at least 30 seconds to reset network settings
8️⃣Check your device network settings :
- Make sure Wi‑Fi is enabled on your device
- For computers, ensure the IP configuration is automatic or matches your network
- Check that network drivers and software are up to date
9️⃣ Support :
- If the issue persists, contact Tango support
- Provide:
- Type of connection (VDSL or Fiber)
- Model of your FRITZ!Box
- Whether the issue concerns Wi‑Fi, cable, or both
