3. According to your question, the question of the line can be excluded (because you have tried it with his line, and it is still the same) You can try it with a different network card, and explain that the root computer system has nothing to do with it.

4. In addition, let me explain, if there is a telecom blocked route, it is not a problem for ordinary ADSL users to pick up three users, according to the normal situation, do not exceed three users, in other cases, other companies have a lot of computers more than a dozen, still a wide user Internet access, never seen the blocked route.
