AVM’s FritzBox is one of the most popular routers in this country. In particular, top models such as the FritzBox 7590 or FritzBox 6591 Cable score with a multitude of functions and fast WLAN – so it is hardly surprising that the devices are widespread in Germany. Compared to routers from other manufacturers, the FritzBox is also easy to use: the menus are easy to understand even for laypeople, and information on activated functions and problems can be read from the LEDs on the device. But what does it mean when the FritzBox flashes? COMPUTER BILD explains what the lights on the router are all about.
FritzBox: “Power” flashesDepending on the model, the LED on the far left bears the designation “Power”, “Power / DSL”, “Power / Cable”, “Power / LTE” or “Power / Fiber” – depending on whether the FritzBox is equipped with a modem. If the LED is solid green, there is a power supply and internet access is available. After a (re) start of the router, the LED flashes to indicate that it is establishing a connection to the Internet provider. This can take up to ten minutes. If the LED is still flashing after this time has elapsed, the connection is not established. Go through these steps until you find the cause:
- Call up the FritzBox menu (http://fritz.box/ in the address line of the browser) and click on system and Events. The router describes the problem here.
- Check the cables on the router and the DSL / cable socket or the fiber optic box. Are all cables firmly plugged in? Are the strings possibly damaged and could be defective?
- Is there a problem with your internet provider? Find out more from your provider or on the website Dysfunction.
FritzBox: “Info” lights up redEvery FritzBox has the “Info” LED. If it flashes red, the reason is usually a faulty telephone and internet connection or a failed update. Call up the overview page of your FritzBox to find out the exact error there. In the event of a faulty connection, check your provider data for Internet access under Internet and access data their correctness. If the update fails, restart your FritzBox by briefly disconnecting the power supply. If you have any problems, please contact AVM support.
FritzBox: “Info” flashes greenIf the “Info” LED flashes green, the FritzBox is performing a system update in most cases. In this case, do not disconnect the power supply, as this can lead to a defect in the router! Other reasons for the LED to flash green are the transfer of the WLAN security settings to a USB stick and the registration of a DECT telephone or smart home device on the FritzBox. Under system and Buttons and LEDs you can assign events to the “Info” LED and be informed, for example, when a new message is available on the answering machine.
FritzBox: “WLAN” flashesIf the “WLAN” LED lights up continuously, the WLAN of the FritzBox is active. If it flashes, the FritzBox activates the WLAN. This is often the case after a restart or after changing the WLAN settings. If the “WLAN” LED does not light up, the WLAN is deactivated. Switch it on again by pressing the button next to the LED.
What does the “Internet” LED mean?
Older models have an Internet LED. FritzBoxes without a modem like the FritzBox 4040 indicate a problem with the internet connection by flashing. Check the internet connection of the connected modem or modem router. In the case of a FritzBox with a modem and telephone system, if the “Internet” LED flashes, there are new messages in the mailbox of your provider, such as e-mails, faxes or voice messages (if the provider supports the function).
LEDs “Fon / DECT”, “FON” and “Fixed line”Depending on the model of the FritzBox, this LED has a different name. During a phone call, the LED lights up continuously. A flashing LED informs (as with the “Internet” LED) of new messages in the provider’s mailbox.
What is the “DECT” LED all about?
Older FritzBoxes have their own LED for DECT radio connections. If the LED lights up, this indicates that the DECT base of the FritzBox is active. If it flashes, a cordless telephone or smart home device is registering with the router.
