ADSL problems on 160m

I did have problems with my net connection when I installed DSL modem

First put ferrite rod on all wires into the modem. This didn't work for me.

I was only able to run with 50w on 160m before the modem didn't work.
I designed a filter 5 order  LC filter.
After installing the filter on the lines problem disappear.

Schematic and pictures can be view here
