Disappointed but not shot

I will not be too long.Pour be honest, I did not try to dig my cervelle.j'ai installed the software that came with and then I connected my Bluetooth Trust and "horror" I lost my internet connection (red cross on my connection icon). I have all retired with uninstalling the software and a little fiddling I could recover all (oufff). Why? I do not know (not experienced enough). Still, I have not sought to remettre.Dommage because I intended to do me a plaisir.Peut be that someone will one day me expliquer.Encore necessary that I ask.
