Exactly what he says a colleague, or a bad ECM, or the card has too many peers on the card, take
another peer card,your DM has nothing to do with that, it can create your network problems, but then the entire CS blocked.
Ask a few of the peer why this works, maybe he download
some material,download a program such as the RS, or torrent, so he withdraws completely net, so you block, though .. doubt it, but it is sometimes the case that you just look when he downloads a movie, ..
and then comes to these things, but I say that is not normally!!
