Signal levels can cause issues but it generally ends up causing loss of block sync (connection). A noisy signal can cause the occasional retransmission but you have to realize that it's linking up at approximately 57mbit downstream (256 QAM), a noisy 57mbit link will still provide you with your allocated 3mbit. Allowing cable modems with very poor signal levels to re-sync at a lower bitrate would slow down the rest of the network. -- Matthew S.
