Cannot Establish a WLAN Connection
Ruling Out Interference Caused by Other Wireless
Networks
If there are other devices in the immediate vicinity of your
FRITZ!Box that use the same frequency band, simultaneous
use of frequencies can result in mutual interference (for ex-
ample, fluctuations or interrupted connections). Disruptions
can be caused by other WLAN base stations, but also by de-
vices like baby monitors, game consoles, garage door open-
ers, Bluetooth devices, or wireless AV bridges, which also use
the 2.4-GHz frequency band. In this case, please test a differ-
ent radio channel for your FRITZ!Box.
Alternatively, you can set the radio channel to “Autochannel”.
This enables the autochannel function, so that the FRITZ!Box
searches for the best WLAN channel itself.
For applications that rely on a steady, high throughput rate
(“streaming”), you should use the 5-GHz frequency band.
This radio band provides more channels and is subject to sig-
nificantly less external interference.
To set the radio channel in the user interface, your computer
must be connected with the FRITZ!Box by network cable or
wirelessly. If your computer is connected via WLAN, continue
with Step 2 of the instructions below. In this case, note that
the existing WLAN connection is interrupted as soon as you
apply the changed settings. Afterward you have to reconnect
your computer with the FRITZ!Box.
1. Connect the FRITZ!Box to a computer using a network ca-
ble. Proceed as described in the section Connecting
Computers to the LAN Port from page 17.
2. Start a web browser.
3. Enter fritz.box
in the address field.
4. Open the “WLAN / Radio Channel” menu in the naviga-
tion bar on the left.
5. You may have to enable the “Adjust radio channel set-
tings” option.
6. Select a different radio channel from the “Radio chan-
nel” list.
