Title: Fritzbox 7590 AX not talking to DSL
Post by: srt on May 13, 2022, 06:53:20 PM
Hi,
I have the above new router which I wanted to replace my older 7530 with  as an extender (mesh). Unfortunately after a nightmare attempting to get into the user interface which was all in German,I’m not, I finally managed it and as far as I can tell I’ve set it up with my Zen settings but after several attempts it just would not connect to the internet even with Zens tireless efforts over the phone it was felt to be incompatible to U.K. broadband and that I should return the 7590 AX  :(. I still feel this is wrong as it recognises all my other hardware in its user interface and that there must be a solution but just what I don’t know. I’ve sent AVM a tech request for advice but just wondered if anyone here might have an idea.
Thanks :)

Hmm . . . A long shot but as you say "the user interface which was all in German", wonder if you have a device for xDSL over ISDN -- which will never connect -- instead of xDSL over POTS?

What size is the xDSL socket on 7590AX? Is it 8P2C or 6P2C? (RJ45 or RJ11 in size?)  :-\

My thoughts too.
The socket type may not be a reliable indicator though as Fritz do use an RJ45 type for UK DSL on some models.

Ah, I wasn't aware of that fact.

Thanks for your inputs.
Just to clarify a bit. I managed to get the user interface operating in English but tbh I am pretty much at a loss as to the type of socket size but the cable I used for the 7530 which I am still using will not work with the 5790.
The 5790 came with a TAE connector on one end ( for phone) and a regular one for the face plate. It also has a black converter similar looking to a filter which the TAE end connects to and then it plugs into the DSL port on the 5790 but I still get no internet handshake However that cable set up will work ok with the 7530 ???
I still await a reply from AVM Fritzbox but surely their routers are able to work in the U.K. as my older 7530 supplied by Zen does? Incidentally I understand the 7590 does not utilise ISDN so not sure if that helps?

In simple terms, if you got a German version of the Fritz, then it won't work in the UK. It's to do with the type of Annex that is used in Germany and Poland (Annex B) vs. the rest of Europe, which is Annex A. Here's an explanation of that in relation to Draytek, but I believe it's also applicable to other modems.

https://www.draytek.com/support/knowledge-base/5002

Another thing to consider is that if you have no ADSL2+, then 7590 won't work.

Finally, are you connecting it to the right socket? (light grey)

If all wrong, it's possible that the modem is faulty. I've seen two Drayteks with faulty modems - they simply couldn't connect to DSL.

I downloaded the manual for the 7590 and found the attached. May confirm suspicions.

I'm not sure what to make of it. Very confusing.  ???

Yep, why no reference to annexes for VDSL when it does for ADSL?

I have a 7590 not AX version. Fritz!boxes are normally universal so can be used thoughout the EU. I have checked the Configuration file as this lists all possible connections. Sanity check :fingers: What setting have you put in? English and Region United Kingdom, Line settings Annex A, Internet Connection VLan 101 Pbit 0, ATM DSL set as auto (but will revert to something!!).

Again thanks all. I’ve set it to English U.K. but as to the line settings I’m a bit of a novice and would appreciate a guide as to how to do what you’ve indicated.
I am sure the DSL cable is plugged in correctly as the three I’ve been using all work fine with the 7530. Interestingly the fault checker shows DSL interrupted and that ipV4 is not connected.
In all honesty I have requested a return to the seller as it isn’t fit for U.K. operations but will be more than happy to keep it if only the damn thing would connect with internet  :-\

Because Fritzboxes do both VDSL Annex A & B (POTS & ISDN) via their single RJ45 port.

Just updating. The business I am looking to return the Fritzbox to seem to want to delay matters and asked for pictures of the box. I have done so and spotted a section on the boxes back whic translated says “ This product is designed for the following network access interfaces
provision of public telecommunications networks in Germany:
DSL connection with or without a splitter”. So it will not work in the U.K. as Edinburgh lad stated earlier. I will pursue return and cite fit for purpose consumer rights act.
Thanks for all your input  :)

Glad you managed to identify the issue.

Also, for information, there seems to be misinformation about Fritz's Annex A and B, some people wrongly believing that Annex B should be chosen on VDSL lines. So, for all exchanges (Broadcom and Infineon/ECI), it should be Annex A on the Fritzbox. The only time when you should choose Annex B is when your cabinet has the Ikanos chipset.

However, if you choose Annex B for Broadcom/Infineon, Fritzbox will ignore this setting and treat it as if it was Annex A, which is why probably some have been successful with running their connection with Annex B setting - still unaware of the difference - thinking/being convinced that this is the correct setting.

Such Fritz boxes are still aimed for the international market (POTS).

Confusingly, Annex B also refers to ISDN, which is what is used in Germany and Poland, but not by all providers, which adds to the confusion. In such cases, modems are identified as working with specific providers, for example modem working with Orange or 1&1 or Deutche Telekom in Germany, or TPSA or Dialog in Poland, rather than modem for Annex A or Annex B.

Therefore, if you order telecoms equipment from Germany especially (in relation to Fritzbox), you have to pay attention what market it is for. If it's for the German market, it won't work in the UK. If it's for the international market, it'll work in the UK. Then, you can choose 'Annex A' or 'Annex B' in Fritz's settings, depending on the chipset installed in your cabinet (Annex A for most).

This is the problem with FritzBoxes only being available from Zen and there being no official retail sellers. Years ago I bought a few 7490s from a reputable VAT registered UK business - still in existence! They were marked as "international" and work fine to this day. I've been looing for a couple more and trawled all the usual places. Discounting Amazon and eBay there are none to be had.* So where did you get yours?

*None that pass my bargepole test, UK, VAT registered etc

Trunk networks... aka leetline sell Fritz!boxes .. try Amazon currently £133 for UK version 7590 supplied by Trunk Networks.

I think the OP referred to the newest (ax) model, which is difficult to get in the UK, and considerably more expensive than the 7590. The same applies to the FTTP version (the FTTP version is being looked into to be provided for the UK market).

Also, for everyone's information, the 7530ax has a Broadcom chipset (7530 has Lantiq), whereas 7590ax Lantiq. But you should always double check before committing to buy.

Was thinking of Woolwich comment about places you can buy them... 7590 is also Lantiq chipset. The AX version is not really for sale in UK yet. So the Config file may not have all the right info in it yet.

Thanks, I picked one (7530) up from Zen in the end.

The AX versions are a lot more money to be of interest, I'm not sold on WiFi 6 but if it was only a couple of quid difference.... But as you can't buy them officially anyway, no matter.

So which chip is better?
Title: Re: Fritzbox 7590 AX not talking to DSL
Post by: Edinburgh_lad on May 18, 2022, 11:04:36 AM
I personally don't think you can argue that this one is better or the other. I think it's a matter of experimenting. For example, my Draytek was worse on my line than my Fritzbox (both Lantiq, though different types) and I noticed no specific difference between Zyxel and Fritzbox on my poor line, so using the latter, even though I'm connected to Huawei.

However, a number of people swear by 'matching' the chipset of the modem to that of the exchange. Not sure how they reached that conclusion, as a number of factors could potentially affect a line and its performance (heat, rain etc.). I'd say only lab tests (in controlled environment) would be the only way of confirming whether matching the chipset to the exchange helps.

The matching chipset thing is often down to slight implementation errors, if they match between chipsets then its less likely to cause a problem.

Or cases where there is a vendor specific extension, which I believe Weaver benefits from on ADSL as Broadcom had their own form of additional error correction/re-transmission.

So in an ideal world it should make zero difference, and in some combinations it wont, but in other combinations it will.  Like you said, its not a hard-fast rule as something that benefits one line might be irrelevant to another.  eg If you have an extremely clean line on Fastpath then any benefits from a vendor specific error correction mode is going to make next to no difference.
