Sorry, I should have said I was talking about cable DSL - this is a common drawback to cable DSL and
AFAIK no work around other than changing connection/ISP.......
Begging your pardon, but this is entirely incorrect. It is possible that this respondent's confusion comes from the advertisement and sale of "Cable/DSL" routers, which simply means that they are compatible both with incoming cable digital signals and with incoming DSL digital signals, NOT that the technologies are the same. All of the forms of DSL (ADSL, SDSL, HDSL, RADSL, and VDSL) are based upon the use of twisted pair *telephone* lines to transmit data. DSL, in fact, stands for Digital Subscriber Line, and refers to the use of the subscriber's own existing phone line to transmit this data. Of the types listed above, ADSL is far and away the most common for "civilian" subscribers (home users). Asynchronous DSL has different upload/download speeds (download being faster). For example, I have had ADSL since it first became available here in Cincinnati, in November, 1998. Originally, we got 384 kbps up and half that down. Then within a year, they kicked us up to what they called their "Turbo" service, 768 kbps up, 384 down. About two years ago, they doubled that again, so we get 1.5 Mbps up, .75 Mbps down, for $29.95/month.
ADSL provides inexpensive service because its effective range from the CO (Central Office) is much greater, permitting the provisioning of many subscribers' lines at relatively low cost. For users, however, to whom upload speed is also important (e.g., people running high-capacity servers), SDSL provides an answer. Synchronous DSL provides identical up/down transmission speeds. Its drawback is that its range is far more limited than ADSL, therefore its cost is significantly higher. There are other DSL technologies which exist to meet specific market requirements, such as High Data Rate DSL (HDSL) and Very High Data Rate DSL (VDSL), which may not be available (or even necessary, when you consider it) to all subscribers, and which are commensurately more expensive than standard subscriber ADSL and are often only employed by business, education, research, and military organizations.
Here is the key point with respect to the current discussion: With ANY of the forms of DSL, the subscriber is connected directly to the provider's servers, and every bit per second of his bandwidth is available AT ALL TIMES through that connection. No matter how many subscribers are logged in to their accounts, each has available to him 100% of his allotted bandwidth 100% of the time, assuming no service outage.
Conversely, with cable modem Internet access, just as your regular cable television service goes through a neighborhood collection point, so does your 'net access. In my apartment complex of 948 units, we have at least two such collection points that I have seen, each about 4' x 4' x 2' deep. There may be others, but I have not personally seen their locations. The point is, whatever the advertised bandwidth available via the cable connection, 100% is available only if there is only one user logged on to a particular collection point. As more users log on through that collection point, the bandwidth is allocated among them.
This does not mean that they automatically "use up" x-amount of bandwidth just because they are logged in. If they're logged on but sitting there idling, reading a NY Times Web page they downloaded, for example, they are using and are allocated zero bandwidth. The system is demand-based and bandwidth is parcelled out as users require it. Under many circumstances this works quite well, given that cable transmission permits a higher total bandwidth to begin with, often 3 Mbps or greater.
However, there are circumstances where the bundling of bandwidth becomes an issue. Imagine a case where one of our buildings has 10 school-age teenagers as residents. They come home from school and start downloading MP3s, DIVX movies, the latest Hexxen demo, high-resolution graphics, etc. Or let's say we're talking about adult users, and they read where Windows XP SP2 is available for download from Microsoft, at 278 MB per download. Or someone is into file sharing and is running a Bit Torrent server. Whatever the reason, when the total bandwidth requirement of all current users goes up, there comes a point where it exceeds the total available through the collection point and each individual's bandwidth allocation is decreased. This is the nature of cable internet access distribution, and it is fundamentally different from that of DSL technology.
So, the upshot in the case of the current discussion is that, yes, given the progressive nature of the slowdown, IF he is on a cable modem, his available bandwidth may be decreasing over the course of a time period. However, contrary to what was said below, he does have the option, if it is available locally, of switching to DSL which, although its individual bandwidth may be lower with respect to cable, at least offers ALL of that bandwidth ALL of the time (and may even be significantly less expensive when bundled with enhanced telephone services, as is the case here in Cincinnati).
Cheers, Scott

: I am not confident enough to do a registry clean. I have heard so many : stories about what can happen if you mess up the registry . . .well there are programs you could download to do an automated clean, with stored backup so that you
can restore if something breaks, there are a number I am sure on CNET download, however perhaps that
should be left to him, <grin /> the one I most recently used ( see below) apparently has caused real

from your description it seems that the problem is progressive which makes the cable connection the
likely suspect IMO..... ( unless he uses Alexa, which should have come up in the spyware scans...)
