FRITZ!Box 4040 Serwis

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, then internet access is only possible after consenting to the terms of use displayed on the captive portal. However, the captive portal is not displayed if a HTTPS page is called up first:

  1. Call up an HTTP page (for example our test page in your web browser first.

Now the captive portal is displayed. After consenting to the terms of use, HTTPS pages can be accessed over the internet.

2 Reducing the validity period of IP addresses

Setting the validity period

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 the wireless guest access is used by many different wireless devices on a regular basis, for example when the FRITZ!Box is being used as a hotspot in a hotel or café, the FRITZ!Box cannot assign IP addresses to other wireless devices because all of the IP addresses have already been assigned. Therefore, configure the FRITZ!Box so that IP addresses are only valid for one day:

  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.
