Slow wireless connection according to 802.11ac

The data rate of a wireless connection (WiFi) according to the wireless standard 802.11ac is lower than allowed by the wireless standard.

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 is solved.

1 Establishing a wireless connection to the 5 GHz frequency band

The maximum data rate can only be achieved when the wireless connection is established to the 5 GHz frequency band and the wireless router (for example the FRITZ!Box) uses the wireless standard 802.11ac:

Note:For the following instructions, we used a FRITZ!Box as an example. If you are using a different wireless router, information on how to set it up can be obtained from the manufacturer, for example refer to the manual.

Enabling the 5 GHz frequency band

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Radio Network" in the "Wireless" ("WLAN") menu.
  3. Enable the option "5-GHz frequency band active" in the "Active frequency bands" section, or enable the option "Wireless radio network enabled" in the "5-GHz Frequency Band" section. If the section "5-GHz Frequency Band" is not displayed, enable the Advanced View.
  4. Click "Apply" to save the settings.

Configuring the wireless standard "802.11n+ac"

In the factory setting, the wireless standard 802.11ac is configured for the 5 GHz frequency band in the FRITZ!Box. If you changed the FRITZ!Box's wireless settings, configure the following settings:

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Radio Channel" in the "Wireless" ("WLAN") menu.
  3. Enable the option "Adjust radio channel settings".
  4. Click "Additional Settings" (if available).
  5. Select the wireless standard "802.11n+ac" from the drop-down list for the 5 GHz frequency band.
  6. Click "Apply" to save the settings.

2 Installing the latest driver for the FRITZ!WLAN Stick

  1. Call up our download area in a web browser.
  2. Select the product group "FRITZ!WLAN" and then your product.
  3. Download the latest driver for your FRITZ!WLAN Stick.
  4. Unzip the ZIP file to your computer, for example to the Desktop.
  5. Double-click the file "setup.exe" and follow the instructions.

3 Installing the latest firmware for the wireless router

  1. Install the latest firmware for your wireless router according to the manufacturer's instructions.

    Note:If you are using a FRITZ!Box, install the latest FRITZ!OS as described in this guide.

4 Automatically configuring wireless channel settings

Configure the following settings so that the FRITZ!Box checks the wireless environment at regular intervals and automatically selects the best wireless channel settings:

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Radio Channel" in the "Wireless" ("WLAN") menu.
  3. Enable the option "Set radio channel settings automatically (recommended)".
  4. Click "Apply" to save the settings. Now wireless connections to the FRITZ!Box are briefly cleared and then automatically reestablished.

5 Finding the ideal location for the wireless router

  1. If possible, place the wireless router in a central location.
  2. Do not place the wireless router directly in the corner of a room.
  3. Place the wireless router so that it is as unobstructed as possible, i.e. not directly in back of or under an obstacle such as pieces of furniture or a heater.
  4. Place the wireless router as high in the room as possible, for example on a shelf.
  5. Place the wireless router so that there are as few obstacles as possible between it and other wireless devices. Especially metallic objects or objects containing water, for example radiators, refrigerators, or even houseplants, significantly reduce the quality of the wireless signal.
  6. Place the wireless router away from other transmitters, for example microwaves, wireless speakers, or Bluetooth devices.

Now the wireless router and the FRITZ!WLAN Stick are ideally configured. You will now achieve the greatest possible wireless range as well as the highest throughput between your FRITZ!WLAN Stick and the wireless router.

NoteIf these measures do not sufficiently improve the quality of the wireless connection, you can use a FRITZ!Repeater in accordance with wireless standard 802.11ac to increase the range of the wireless network and the throughput of the wireless connection.
