If errors do occur and you have followed the above steps correctly, you may just have a bad cable. Try another cable. 100Base-T hub or to a switch. Hub 24 or 24M which are both Class II hubs that autosense the speed of each port to be either 10Mbps or 100Mbps. First, each cable between the hub and the end node must be 4-pair Category 5 cable with a maximum of 100 meters.
Segmentation is the act of dividing the network into smaller parts or collision domains.
Each segment will then have fewer users on it. Fewer users on a segment means less traffic which makes collisions less probable. The lower the collision rate, the higher the overall performance. Add a router, bridge, or switch to your network infrastructure.
