Hi Tobias,
maybe a look into the DSL spectrum display in the fritzbox will show
some hint to decide its DSL related or just on the Network level
it need a bit experiences to interpret that display, but basically if
there are gaps in the spectrum there is definitely something wrong.
could be the splitter or even the cable passing a waterfilled tube.
an simple u72 passing 4m water can cause strange effects, which you
even will see in the spectrum.
i experienced once at a client site someone drilled holes in the wall
for mounting speakers, he cut a bit of insulation of the cable and the
screw was making contact to one of the wires.
Every switch off of the FL lamps in that office caused the link to retrain.

We have this VDSL2 line at one of our customer sites, which aquired
high packet loss from one day to the other ...
we are using a fritzbox 7390 at the site and according to its log
there are no problems, also the DSL Information tab does no count
a high number of errors ...
Here are the smokeping observations of the link

Any hints on getting this fixed.
