Reminder to self: check if FritzOS 7.50 has become available for Fritz!Box 7490

Posted by jpluimers on 2023/03/31

This post is a reminder to myself to check if Fritz!Box 7490 can be upgraded to the FritzOS (sometimes spelled Fritz!OS or FRITZ!OS) 7.50, which is the firmware that introduced WireGuard on various Fritz!Box models.

Initially it wasn’t available for the wildly popular Fritz!Box 7490 series which, at the time of writing was still a current Fritz!Box model, has been wildly popular in The Netherlands because of (now defunct) internet provider XS4ALL started shipping it to customers almost 10 years ago ([Wayback/Archive] Property:XS4ALL – BoxMatrix).

So I asked [Wayback/Archive] Jeroen Wiert Pluimers on Twitter: “Is there any information if (and hopefully estimate when) the @AVM_NL @AVM_DE 7.50 firmware is going to be available for the (in The Netherlands very well sold/distributed) Fritz!Box 7490 model? FritzOS 7.50 supports @WireGuardVPN: a big step forward.”

FRITZ!Box 7490/7390 comparisions (via: Vergleich AVM FRITZ!Box 7490 und FRITZ!Box 7390 – YouTube)

Posted by jpluimers on 2022/08/12

Not sure why failed to post this on 20140525, so I put it in the scheduler again. In the end I got a Fritz!Box 7490 and though the 

In 2013, [Wayback] Fritz!Box replaced the 7390 top model with the 7490 and I [Wayback] might get get soon when ADSL (which still has a Fritz!Box 7240 attached) is upgraded to fiber.

So here are some differences partially from the English FRITZ!Box and German FRITZ!Box Wikipedia page between the [Wayback] Fritz!Box 7390 and [Wayback] Fritz!Box 7490, partially from the below video:

About cooling: according to the video both run the same temperature, either because the air cooling of the 7490 is better. I’m wondering if that is the same when running inside a closet.

[Wayback/] has a Fritz!Box 7490 review that indicates 802.11ac and USB3 might not be as fast as you’d hope.

Reading the [Wayback/] 7490 reviews, I might just ask xs4all to get me a 7390, not a 7490.

PS: I need to research [WaybackUSB over LAN in more detail, especially the [Waybackopen source project USB IP.

Fritzbox 7490 ISDN landline and intenral ISDN S0 bus links

Posted by jpluimers on 2022/08/08

Somehow failed to post it on the scheduled date 20150331, not sure why.

Though ISDN has been phased out in The Netherlands as and almost phased out in Germany, you can still use end user Terminal Equipment on the internal S-bus.

Since scheduling the post for 2015, the same information as the original diagram below appeared in text form on Wikipedia and there it also adds TAE connector information: Fritz!Box: Belegung der kombinierten DSL-Telefon-Buchse – Wikipedia

Die Anschlussbelegung der Kombibuchse ist wie folgt:[44]

  • Pin 1: ISDN 1a
  • Pin 2: ISDN 1b
  • Pin 3: analog La
  • Pin 4: DSL
  • Pin 5: DSL
  • Pin 6: analog Lb
  • Pin 7: ISDN 2a
  • Pin 8: ISDN 2b

Der RJ-45-Stecker am grauen DSL-Zweig des Y-Kombikabels zeigt folgende Belegung:[44]

  • Pin 4: DSL
  • Pin 5: DSL

Die übrigen Pins sind unbenutzt.

Am schwarzen Telefonzweig ist der RJ-45-Stecker folgendermaßen belegt:

  • Pin 1: analog La
  • Pin 2: frei
  • Pin 3: ISDN 2a
  • Pin 4: ISDN 1a
  • Pin 5: ISDN 1b
  • Pin 6: ISDN 2b
  • Pin 7: frei
  • Pin 8: analog Lb

Somit ist ein direkter Anschluss an ISDN möglich, für analoge Anschlüsse liegt für Deutschland ein Adapter auf TAE bei:

  • Pin 1 RJ-Buchse auf Pin 1 TAE
  • Pin 8 RJ-Buchse auf Pin 2 TAE

Ein normales Kabel mit TAE-Stecker und sechspoligem RJ-Stecker, wie es für den Anschluss analoger Telefone an eine TAE-Dose verwendet wird, funktioniert nicht.

Bei entbündelten Anschlüssen (ohne analoges oder ISDN-Telefon) kann ein direktes Kabel verwendet werden.

Das Kabel für deutsche Anschlüsse:

  • Pin 4 RJ-Stecker auf Pin 1 TAE
  • Pin 5 RJ-Stecker auf Pin 2 TAE

Fritz!box 7590 interface extremely slow : fritzbox

Posted by jpluimers on 2022/08/05

I tried the solution in [Wayback/] Fritz!box 7590 interface extremely slow : fritzbox (remove the some 30-40 unused machines from the network overview), but it didn’t matter: since Fritz!OS 7.x, the Fritz!Box 7490 UI is just very very slow: each page takes 10+ seconds to load.

Hopefully I can get rid of these and move to pfSense based hardware eventually.

Some links on using and updating Let’s Encrypt certificates for internal servers

Posted by jpluimers on 2022/02/01

Sometimes it is easier to have current and public CA signed TLS certificates for internal servers than to setup and maintain an internal CA and register it on all affected browsers (including mobile phones).

One of my reasons to investigate this is that Chrome refuses to save credentials on servers that have no verifiable TLS certificate, see my post Some links on Chrome not prompting to save passwords (when Firefox and Safari do) about a week ago.

Below are some links for my link archive that hopefully will allow me to do this with Let’s Encrypt (msot via [Wayback/Archive] letsencrypt for internal servers – Google Search):
