It has not been proven that I am compromised. Since it appears to not be
a cable modem problem then this discussion can end now.

Thank you for taking the time to reply and try to help!

Do you have any idea who your ISP is? I don't think it's their
problem, but I'm curious who it is because I've never heard of such
low speeds being offered by a cable ISP.

Is it possible that they throttle you after a certain amount of
activity?

Well, the indicators point to your PC. That's all any of us can go by.

Nothing personal, but we have no reason to trust that you perform safe
hex. After all, you have a problem you're trying to fix, so apparently
the condom broke, if you know what I mean.

Firewalls are notorious for bugging their owners to the point where
the owner allows something that they shouldn't have allowed, or they
allow something that later gets hijacked by malware. A router makes a
better firewall than a firewall does.

You said the slowness takes awhile to show up, so be patient and keep
monitoring.

>kill my connection?

It could, especially since your connection is throttled down so low to
begin with. You're not that far above dial-up speed, so any extra
network activity might be enough to be noticeable.

You keep saying you're losing your "modem speed". I know what you
mean, but it sounds funny because the problem likely has nothing to do
with your modem.

Your firewall is on the same PC you're trying to protect. There isn't
a whole lot of protection there.

You're welcome.

Now you're insulting me. I don't know who my ISP is? That's right, it
was connected in the middle of the night while I slept by the modem
fairy. We're way off topic for a cable modem newsgroup. This discussion
ends here.

That implies 384 kilobits per second.
Are you sure it's not KBps - kilo*BYTES* per second ?
Mine is throttled to 6144/512 Kbps which is 16x/3x yours.
Your's sounds more like a low rate DSL speed rather than cable.

A router protects you a lot more than a software firewall and can
be had wireless for like $40-60 (Netgear/Linksys) on sale these days.

Let the router take the hit on all that incoming crap that's trying
to access your PC and your firewall can handle mostly the outgoing
situations (malware, etc) and not have to be bothered with most
incoming attempts.

Have you looked into how much memory you are using when this starts
slowing down ? Is most of your memory exhausted when it fails ?
You may want to look at the size of your pagefile too.

Snip It All..

If my computer was compromised, why would that drive my cable modem
speed down and what would rebooting the computer do to temporarily stop
the compromise?
