This guide provides you with tips on how to fix connection dropouts between your streaming device and your network.
Is only the internet radio not working properly?

Tips to improve Wi-Fi stability
1. Check if your router/network is prepared for music streaming.

2. Place router and streaming speakers optimally
For optimal sound experience and a stable network connection, the right placement is crucial. Here are a few tips:
- The router should be placed as centrally as possible in the apartment or house and high up (e.g., on a shelf instead of the floor).
- Place your router and speakers as free as possible and not behind furniture/TVs or in a closed cabinet.
- Place sources of interference such as microwaves, Bluetooth devices, baby monitors, cordless phones/base stations (DECT), large amounts of water (e.g., aquariums), or plants (rubber trees), etc., as far away as possible from the router/speaker.
2. Choose the optimal Wi-Fi channel (2.4 GHz & 5 GHz)
Many routers are set to “Auto,” but automatic selection is often unreliable. Manually setting a less-used channel can significantly reduce interference.
- 2.4 GHz: Ideally, use only channels 1, 6, or 11 (usually non-overlapping).
- 5 GHz: More free channels → usually less critical.
Many routers offer a channel analysis that shows you which channels are overloaded.
3. Use Wi-Fi repeaters or mesh systems
In larger apartments or with many walls, a single router may be overwhelmed. Thick walls, especially those made of concrete or containing metal, can greatly attenuate the signal. Here, using a Wi-Fi repeater or access points and mesh is worthwhile.
Repeaters: simply extend the signal and are good for moderate distances.
Mesh systems: multiple Wi-Fi stations/access points work intelligently together → ideal for stable coverage. Thus, mesh is ideal for large or winding apartments.
4. Relieve the network and reduce sources of interference in the household
Many active devices can overload the router. Tips:
- Disconnect unused devices from Wi-Fi.
- If possible, use LAN cables for your TV, PC, streaming box, etc.
- If necessary, distribute devices to the guest network.
Many electronic devices transmit near 2.4 GHz and can cause interference. Increase the distance between the router and such devices as wireless headphones, smart home hubs, TVs with active Bluetooth, USB 3.0 devices (can interfere with 2.4 GHz), and Bluetooth devices.
5. Use alternatives to Wi-Fi
As mentioned in point 4, too many active devices in your Wi-Fi network can overload your router. Here are a few alternatives:
- Teufel streaming speakers can be connected directly via LAN if the device has a LAN port.
- If you do not want to lay cables, using, for example, powerline adapters can help.
- There are Wi-Fi access points that can also be used with cables. You could connect these to your router via LAN cable. Alternatively, you can connect these Wi-Fi access points to your router via Wi-Fi and then via LAN to your streaming speaker.
What if the tips do not help?
Why do streaming dropouts occur?
When many Wi-Fi networks are broadcasting in the area, overlapping and interference can occur. The 2.4 GHz Wi-Fi is particularly affected, as there are only a few non-overlapping channels. Therefore, it can help to separate Wi-Fi networks/frequency bands.
Before implementing the tips:
For the control device (smartphone/tablet) and streaming speaker to communicate, both must be on the same frequency band of the router:
- Both devices on 2.4 GHz → works
- Both devices on 5 GHz → works
- Mix of 2.4 GHz and 5 GHz → does not work
Otherwise, the devices cannot find each other on the network.
1. Use only the 5 GHz frequency band.
If your router supports it, set up a separate 5 GHz network with its own SSID.
Using the 5 GHz frequency band for Wi-Fi offers numerous advantages over the conventional 2.4 GHz band. The 5 GHz frequency band is:
- very stable and the connection is more reliable, as there is less interference from other wireless devices, which often occurs in the 2.4 GHz range
- less susceptible to interference, as it is used by fewer devices and therefore has lower utilization.
- higher bandwidth > higher transfer speed
Conclusion: The 5 GHz frequency band is particularly suitable for streaming applications such as internet radio. However, there is also a disadvantage: the range is shorter than with the 2.4 GHz band.
Here's what to do:
- Activate the 5 GHz Wi-Fi and give it its own name (SSID).
- Connect your streaming speaker and your smartphone/tablet to this 5 GHz network.
2. Deactivate the 2.4 GHz frequency band (if separate SSIDs are not possible)
If your router cannot separate 2.4 GHz and 5 GHz, deactivate the 2.4 GHz Wi-Fi completely.
Important:
All other Wi-Fi devices must then also be moved to the 5 GHz network.
This reduces wireless load and often improves the connection – depending on your environment.
3. Use a separate access point
If your router only offers 2.4 GHz Wi-Fi or the network is too heavily loaded:
Use an additional access point that provides 5 GHz only.
- Give this additional access point its own SSID.
- Connect your streaming speaker and your smartphone/tablet with the remote app to this 5 GHz Wi-Fi.
