FRITZ!Box 7360 – Service - Knowledge Base
FRITZ!Box changes the wireless channel that was manually selected
Although you selected a specific wireless channel in the user interface, the FRITZ!Box automatically switches to a different channel. The following error message is then displayed in the event log of the FRITZ!Box:
- "A very strong source of interference was detected on channel [...]; channel switched automatically."
1 Channel was changed due to strong interference
The FRITZ!Box detected a source of interference on the wireless channel that was selected manually, and this interference greatly impairs the wireless connection. Regardless of the settings in the user interface, the FRITZ!Box automatically switches to a wireless channel without interference to ensure stable and fast data transmissions. If the FRITZ!Box determines that interference is no longer affecting the channel you selected, it automatically switches back to it.
