Lost Internet after you connect multiple PCs. Why?
Good day to all. Recently I was asked to help at a local school. The bottom line:
Internet access is just across the school, except for room # 2. After the group of computers located in office No. 2, give Internet access, it falls in the whole school, except this office.
Objective: to Establish Internet access in all rooms.
All computers are connected in a separate LAN, on the principle that the office - LAN. In the offices use the switches.
The question, I think, is clear: where do I start?
Could there be a problem in computers in office # 2? Is it possible that they block Internet access in the whole school?
