Download speed from an FTP site obviously depends on how busy + the FTP site is, among other variables. Yes, but finally someone is getting to my point: The "other variables" are so oppressive on the "World Wide Wait" that they appear to make ones connect rate with his ISP the least of his worries; there's usually a bottleneck somewhere else. I could also keep up with a 40k streaming audio feed with a 45k connect on a conventional K56 modem, but the 40k streaming audio feed is virtually always dropping out every few seconds from "net congestion" errors anyway, and I have to drop to a feed with a slower sampling rate. I can't see how a cable modem or a 128 ISDN connect would change this. If, for example, an FTP site is only moving a file at a quarter of my connect speed, won't the throughput be just as lousy no matter how much faster my modem device can connect to my ISP? I can obviously see that _if there are no other bottlenecks_, a super-speed device can be pretty impressive, but in my experience there are _almost always_ other bottlenecks that prevent even a conventional modem from being used to the capacity of the connect speed. Seems to me you'd also have to take care of every other problem constricting throughput between you and your target URL. Again, if some TCP/IP maven can explain the part of this I'm missing, I'd be grateful.

When I was using an analogue modem, I had the same problems with streaming audio feeds that you describe. With ISDN, those problems have gone away. No more dropped connections. No more "net congestion" errors. For me, ISDN is a very significant improvement. That includes FTP, although my experiences are not based on downloading porno from overloaded sleaze sites. Your statements do not in any way reflect my experiences with internet access. -- Frank
