FB 7520/30 - no DSL settings/device after fresh install

Hi guys,

I got today my Fritz!Box 7520 where I installed OpenWRT 22.03.3 as described here: https://openwrt.org/toh/avm/avm_fritz_box_7530

It went well and without any problems, but after booting up and adding necessary modem firmware files I still don't have any possibility to set up a DSL connection.

I read about a patch for some models of 7530 (which my 7520 basically is), but I did not find anything yet how to apply them.

Does someone have also the same problem?

Thanks in advance!

ah damn, is just one digit ... inside of 22.03.3 are much "3s" so I just imagined it's the right version ...
shame on me.

thank you!

I rephrased this sentence on the device page just today into its current form. If you have a suggestion how this could be phrased clearer, please let me know.
NB: I was trying to come up with a sentence that doesn't need editing once 23.x is released.

I think an also misleading aspect is the box with unsupported functions which lists only "DECT" - and 22 and 23 are close to each other and can easily be confused. Maybe it could help to put in brackets after 23.x something like (22.x and below are not supported) - it could catch more attention to read the sentence again.
