[Info] [Erfahrungsbericht] Powerline an VDSL 35b: FRITZ!Powerline 1220 vs. devolo Magic 2 – massive Unterschiede bei DSL-Störungen und eine Lösung

[wg2003]

Hi

If the VDSL Performer status is 'yes', then I presume your Devolo are communicating with the Fritzbox via TR-064. However, at some point in FritzOS, I remember I had to activate TR-064 (it was as a separate tab), but because I'm on FTTP, I can't see it, or they have deactivated it.

You used to be able to download the support information using the Devolo app for Windows, but I don't know if it's still the case. I remember they tried to retire the Windows app in favour of Android and iOS apps because these days, most use their phones to set up everything.

I'm on the same version of tgc Devolo app for Android, and I use MS Outlook app as my email client. Try setting up a Microsoft email address and use the app to see if you're more successful in getting the Zip file.

TR-064 in FritzOS is configurable in Permit Access for Apps in Home Network > Network > Advanced Network Settings

Thanks for pointing me in the right direction!

I managed to generate a ZIP file using devolo Cockpit 5.2.0.185 under Windows. The DSLCOEXISTENCE entries were indeed present in the .cld files, but Base64-encoded, which explains why my initial text search found nothing.

After decoding the files, I found the following entries on both my Magic 2 adapters (MT2999 and MT3157):

DSLCOEXISTENCE.GENERAL.ENABLE=YES
DSLCOEXISTENCE.GENERAL.RUNNING=YES
DSLCOEXISTENCE.GENERAL.GATEWAY_SUPPORTS_TR064=YES
DSLCOEXISTENCE.GENERAL.GATEWAY_COMPATIBLE=YES
DSLCOEXISTENCE.GENERAL.STATUS_CODE=-231
The diagnostics also report:

• DSL profile: 35b
• DSL link status: Up
• Gateway: Fritzbox
• DSL information queries: 53 / 43
• Measurements: 11 / 13
• DSL disconnections: 0 / 0
• Target power mask applied: YES / YES

Interestingly, both adapters report mimo_vdsl17a as their configured power mask profile, although the DSL connection uses profile 35b. The available profiles also include mimo_vdsl35b.

This is strong evidence that the adapters are actually obtaining DSL connection information from my FRITZ!Box 7690, rather than merely identifying it as compatible.

Two questions remain:

1. Do you happen to know what status/error code -231 means?
2. Is the use of mimo_vdsl17a on a VDSL 35b connection expected behavior?

In any case, thanks again for your help. Without your suggestion to inspect the diagnostic dumps, I would probably never have found this information!

Did you change the profile on the Devolo adapters? There's an option to have either Profile 17 or 35. This is done in the Powerline settings of Devolo (I have an English version.) Please note that you would need to do it on *each* Devolo adapter, not just one of them.

Yes, the adapters query the Fritzbox for the SNR margin and, from what I remember, also errors. This influences the operational mode of Devolo adapters.

With Devolo Performer, I found the impact of powerline on my DSL line at the time minimal, if not at all.
