This, however, shouldn't affect the quality of downloaded data. The TCP protocol contains a 16-bit one's compliment checksum value in each and every packet, which is used by the receiver to either accept and acknowledge (if the checksum is correct), or dump and await retransmission. Thus, if there are transmission errors, the TCP/IP stack should be detecting them and rejecting the erroneous packets -- and should keep rejecting them until a good packet arrives. If the degredation is serious, what _should_ happen is that the connection will appear to be extremely slow -- you shouldn't wind up with corrupted data.
Yes, you make perfect sense. In fact my own experience was a choking off of the data stream, when my integrity limit was surpassed, yielding very low throughput until I manually set the NIC away from autodetect. Bill's CRC problem is a VERY intriguing one.
