FRITZ!Box 7330 – Service

Cannot establish a wireless connection

A wireless device (for example a notebook, smartphone, tablet) cannot establish a wireless connection (WiFi) to your FRITZ!Box.

Important:Some of the settings described here are only displayed if the advanced view is enabled in the user interface. The configuration procedure and notes on functions given in this guide refer to the latest FRITZ!OS

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

    • Apple iOS (iPhone, iPad, iPod touch)

      1. Tap "Settings" on the home screen.
      2. Tap "Wi-Fi" in the "Settings" menu.
      3. If wireless LAN is turned off, tap the "On / Off" icon.
      4. Check whether the name of the wireless network (SSID) of your FRITZ!Box is displayed in the list of available connections.
    • Android (for example Google Nexus, Samsung Galaxy)

      1. Tap the "Settings" icon on the home screen of the Android device.
      2. Tap "Wi-Fi" in the "Settings" menu.
      3. If wireless LAN is turned off, tap the "OFF" icon next to the "Wi-Fi" option to enable wireless LAN.
      4. Check whether the name of the wireless network (SSID) of your FRITZ!Box is displayed in the list of available connections.
    • Other operating systems or wireless devices (such as network printers, game consoles)

      1. Use your wireless device to search for wireless networks in the vicinity.
      2. Check whether the name of the wireless network (SSID) of your FRITZ!Box is displayed in the list of available connections.

2 Installing the latest software for the wireless device

  • Install the latest driver for your computer's wireless network adapter or the latest operating system (for example Android, iOS) for the wireless device.

    Note:You can find information on updating the wireless network adapter or wireless device in its manual, or consult the manufacturer directly.
    You can find the latest drivers for the FRITZ!WLAN Sticks in our download area.

3 Optimizing the FRITZ!Box's wireless settings

Optimize the FRITZ!Box's wireless settings in order to guarantee favorable conditions for setting up the wireless connection.

The following steps are only necessary if the wireless device does not support configuring wireless connections at the touch of a button (WPS PBC - Push Button Configuration) and you therefore have to configure the wireless connection manually:

Note:WPS is supported by computers with Windows 7 that have current Intel wireless network adapters, many media players, and wireless music systems, for example. You can find information on whether your wireless device supports WPS in its manual, or consult the manufacturer directly.

Preparations

  • Use a network cable to connect a computer to the "LAN 2" port on the FRITZ!Box.

Briefly disabling the MAC address filter

When the MAC address filter is enabled, new wireless devices that are unknown to the FRITZ!Box cannot connect to the FRITZ!Box. Therefore, make sure that the MAC address filter is disabled:

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Security" in the "Wireless" ("WLAN") menu.
  3. Enable the option "Allow all new wireless devices".
  4. Click "Apply" to save your settings.

The FRITZ!Box's MAC address filter is now disabled. You can re-enable it as soon as you have completed the configuration of the wireless connection between the wireless device and the FRITZ!Box.

Displaying the name of the wireless network (SSID)

Some wireless devices cannot establish a wireless connection if the name of the FRITZ!Box's wireless network is not visible:

Note:Hiding the wireless network name can represent a security risk (see article in PC World: 5 Wi-Fi security myths you must abandon now).

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Radio Network" in the "Wireless" ("WLAN") menu.
  3. Enable the option "Name of the wireless radio network visible".
  4. Click "Apply" to save your settings.

Changing the name of the wireless network (SSID)

If there are other wireless networks with the same name in the vicinity, wireless devices may automatically attempt to connect to the wrong wireless network. To avoid this, give your FRITZ!Box a unique name:

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Radio Network" in the "Wireless" ("WLAN") menu.
  3. Enter a name of your choice that does not contain special characters in the field "Name of the wireless radio network (SSID)".

    Important:Not all wireless devices support all special characters. Therefore, only use standard Latin letters (not letters such as ä, ë, ö, ü, á, é, í) and numbers in the wireless network name.

  4. Click "Apply" to save your settings.

When you apply the new wireless network name, all wireless connections to the FRITZ!Box are cleared. You must then reconfigure wireless connections to the FRITZ!Box.
