FRITZ!Box 6890 LTE Service

The wireless guest access cannot be used to access the internet

Although wireless devices can register with the FRITZ!Box's wireless guest access, they cannot use it to access the internet. In some cases, new wireless devices do not obtain IP addresses from the FRITZ!Box.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

Simply proceed as described below. After each measure, check whether the problem persists.

1 Opening an HTTP page in the web browser

If the option "Permit login with guest access/hotspot only after consent to terms of use" is enabled, users must consent to the terms of use before they are allowed to access the internet. However, the captive portal with terms of use is only displayed if you call up an https page:

  1. Call up an HTTP page, for example our test page http://service.avm.de. Now the FRITZ!Box displays a captive portal for guest access.
  2. Agree to the terms of use of the guest access.

2 Reducing the validity period of IP addresses

180 IP addresses are available for wireless guest access; they cannot be reassigned until the validity period (lease time) of 10 days has expired.

If you are using the FRITZ!Box as a hotspot in a hotel or café, for example, and many different devices log in to the guest access on a regular basis, the FRITZ!Box cannot assign any IP addresses to new wireless devices because all 180 IP addresses have already been assigned. Therefore, configure the FRITZ!Box so that IP addresses are only valid for one day:

Setting the validity period

  1. Click "Home Network" in the FRITZ!Box user interface.
  2. Click "Network" in the "Home Network" menu.
  3. Click on the "Network Settings" tab.
  4. Click the "IPv4 Addresses" button. If the button is not displayed, enable the Advanced View first.
  5. Enter 1 in the "Valid for" field.
  6. Click "OK" to save the settings.

Removing devices from the user interface

The new validity period only applies to devices that are registered with the FRITZ!Box after the change was made. Therefore, delete all unused network devices:

  1. Click "Home Network" in the FRITZ!Box user interface.
  2. Click "Network" in the "Home Network" menu.
  3. Click on the "Network Connections" tab.
  4. Click the (Delete) button next to the respective device.

    Note:As an alternative, you can also use the "Delete" button under the list of network devices to delete all of the devices that are no longer connected to the FRITZ!Box for which you did not change the settings in the FRITZ!Box.
