Why Broadband Router always has problem under Cable connection but not ADSL connection?

For ADSL, one subscriber shares one line. If your ISP provides you a 512K account then you can enjoy the full 512Kbps on your side. But Cable is different. Many subscribers share the same line. For example, the bandwidth of Cable is 1.5Mbps. If there are 25 users access Internet at the same time then the bandwidth of each user is 1500K/25 near 60K. The speed is just like the traditional modem connection. If there are only 5 users on line at this moment then each user can share the bandwidth to nearly 300K (1500K/5). So, the speed over ADSL is more stable than Cable. The access will hang up when the traffic is heavy over the Cable. It is the reason why many problems only happen over Cable.
