FRITZ!Box 7340 Service

Cannot access the internet over guest access

Although devices can register with the FRITZ!Box's guest access, they cannot access the internet over the guest access. In some cases, new devices do not obtain IP addresses from the FRITZ!Box or internet access is only not possible when the captive portal is enabled.

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

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

1 Reducing the validity period of IP addresses

180 IP addresses are available for 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:

2 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 "Devices and Users" tab.
  4. Click the (Delete) button next to the respective device in the list of "Devices and Users".
