How to setup a FRITZ!Box WLAN 7390 on Swisscom’s VDSL network

I just got myself an AVM FRITZ!Box Fon WLAN 7390 (CH-edition) router to replace a rather aged Swisscom branded Netopia 7347-84 VDSL router I received for my internet subscription. The FRITZ!Box 7390 really is the jack of all trades:

  • ADSL/VDSL modem
  • WLAN 802.11n/b/g/a (including the 5 GHz frequency band)
  • DECT base station for up to 6 cordless phones
  • Telephone system for Internet and fixed-line network phones
  • Answering machine
  • Fax receiver
  • Network attached storage (NAS)
  • UPnP-AV media server
  • Gigabit ethernet
  • DynDNS support
  • A ton of configuration options (a must have for the true gadgeteer!)

Here’s how to setup the FRITZBox 7390 router for Swisscom’s VDSL network. My router is on firmware version 84.04.83. Connect your Mac (or PC) using the yellow patch cable to the LAN 1 port and switch the router on. If your computer is using DHCP it should receive an IP address from the router. The router’s admin user interface can be accessed with or if this doesn’t work just type

Select Annex A for analog phone line or Annex B for ISDN. I don’t have ISDN so I don’t know if Annex B works on Swisscom’s network. I’ve read some reports saying that there were issues ISDN when using the 7390. After setting the Annex the router will perform a restart.

The next screenshot shows the connection information:

This is it, you’re done. Now your FRITZBox will try to connect to the VDSL network. Once the connection is established you should be able to get some information about your DSL connection:

If no connection can be established, check the event log for error messages. By the way: even though the new router is able to re-use the existing sync-settings (DSLAM throughput) from the old router it will also perform a re-sync (or re-evaluation) of the DSLAM throughput performance of your line. My current settings from the old Netopia VDSL router were 22016 kBit/s (receive) and 2320 kBit/s (send) and hopefully that won’t change to lower values with the new router.

  1. Good morning
    I recently installed a Fritzbox 7390 on one analogic line, and have to say it worked nicely and easily (except the incoming numbers are not recognised – I have to check the firmware number according the conversation I found here from 2010/2011).
    Now I have a second Fritzbox 7390 and want intall it on an Swiss ISDN line. Up to now, I found no signal (it works with a Zyxel delivered by Sunrise). There are 3 plugs in the wall: AB1 / U(95V) / ISDN. I connected ISDN with the splitter (from which “line” goes to “DSL/TEL” on the fritzbox by using the Y cable with an adapter). That is certainly wrong and I would be greatful if somebody could give me some advise on how to connect that device.
    Thanks in advance !

  2. Dear Jan,
    I’m interested to acquire the mentioned router. Just a quick quetion what does it means CH version? A versione just suitable for switzerland?

  3. Dear Jan,
    Thanks for that info. I will download the German version and flash that in using the ru* tool. Meanwhile my suggestion to anyone reading this is to stay away from the 85.05.05 Swiss version if you are using analog POTS and value the caller ID feature.

  4. Dear Jan,
    Thanks for your article. I have the same box (CH version) on the same swisscom connection (albeit a worse signal/noise than you) and since updating to the latest firmware 85.05.05 (CH version) I lost caller ID completely. Caller ID was previously mostly OK (sometimes not working but 90% OK) but now I lost it completely. I wrote to AVM but no answer yet. Have you experienced anything like this? Any hints what might be wrong?
    Thanks a lot!

    • Dominic, I’m still on the latest, public, non-international German version of the 7390 firmware. Caller ID works even though I’ve seen some weird 9-digit numbers in the past (which is short one digit as the local numbers contain 10 digits).


  5. Hi Jan,

    Thanks a lot for the answer. I should be ok with the german interface though I’ll probably wait a little more before making my decision.

    I have managed to tweak some settings around and I am getting pretty good consistent speeds (though the router interface still stops responding unless it’s rebooted)

    Thanks again!


  6. Carlos, if you need an English user interface you better stay away from the 7390 until a newer firmware is released. I had to flash my 7390 with the German firmware in order to update to a more recent firmware that actually works like it should.


  7. Hi,

    Thanks for the very useful info. I am thinking on buying one of those boxes to replace the default Motorola unit provided by Swisscom. My question is, have you seen any tangible benefits in the usage of this Fritz box?

    The Motorola unit chockes on bit torrent after 20 mins and only responds after a reboot :(


  8. Hoi Jan,

    merci. Dann werde ich wohl gleich mal bei Digitec vorbei schauen. *freu* Bin seit vielen Jahren treuer FritzBox user/fan/fanatic :þ.

  9. Ich wäre sehr dankbar wenn ihr mir einen tip geben könntet wo ihr in der Schweiz oder Deutschland die internationale variante der FritzBox 7390 erworben habt.


  10. Tom, ich kann mich in der Tat erinnern, dass dieses Kreuzchen auch bei mir nie drin blieb in der internationalen 84.04.83 Firmware. Es hatte aber bei mir keine Auswirkungen, die Telefonie funktionierte trotzdem. In der 84.04.86 bleibt die Einstellung nun drin.


  11. Ich kämpfe auch gerade mit der 7390 an einem analogen VDSL-Anschluss. Internet und BluewinTV habe ich zum Laufen gebracht, die Telefonie weigert sich jedoch standhaft (das Kreuzchen für “Festnetz aktiv” fällt automatisch immer raus). Hattest Du bei Dir diesbezüglich irgendwelche Probleme? Vielen Dank & Gruss, Tom
