Hi Johannes,

I am afraid that the suggestion didn't work out, I have changed the interface to the br-lan and it stills refuses to work. As you can see below I have also changed to the wireless interface, and it happens the same issue. Any other suggestion? Perhaps some of the libs that I have installed are outdated?

Thanks in advance,

Bes regards
