Ok here’s the thing. We’re managing a wide network of computers all running on Windows XP SP3. Our network consists of, starting from the internet modem device, then splits the connection with a switch hub which is connected with a router which is then connected each room that has one 8 port hub with 10 rooms having computers, totaling to 10 hub units. But those 10 hubs are lined to another hub from the next room over. So basically we made them branch out to reach the other rooms (example: Hub 1 directly connects to the net modem, Hub 2 is connected with Hub 1, and Hub 3 is connected with Hub 2, and so on). We’re having some sort of connection problem where a computer would get disconnected from the network for a while, then it gets connected again even if we did nothing. We ruled out possible line and hardware damage and viruses are kept at bay. The router and hubs are working fine, the ports are not dirty or loose, and the LAN cables are alright, no tearing or damage whatsoever on the line and no damage to the RJ plug. The LAN cards/devices on the computers are working perfectly and have no problems. But the disconnection issue with some of the computers still persists. What can be other causes of this? And how could it be resolved?
