Perhaps artemidorus should be using my modem. As has already been
noted,
most users (I belong in this group) have a much higher downstream than
up and so was
I until the end of January.

Suddenly, my 'up' was much higher than my 'down' and I was warned I'd
be billed for
overusage.

February has been artemidorous's dream and my nightmare. Thankfully,
my ISP is
trying to figure out wotsup and won't be charging me.

You've referred to DOCSIS 1 and 2. Could a glitch there be causing
this? If so,
what's the solution? If not...any ideas?

It's not the only problem, btw - but..one at a time..Calvin would be
pleased...:)

Thanks, I hope,

Kathy

What are your actual upstream and downstream speeds?

No. DOCSIS 2 is backwards compatible with DOCSIS 1, but your cable
company almost certainly doesn't have DOCSIS 2 equipment installed at
the head end. The most likely explanation is that your modem is no
longer limiting its upstream bandwidth the way it's supposed to and thus
is using the entire upstream channel rather than sharing with other
users. The upstream limit is set in a configuration file that the modem
downloads from the cable company when it starts up. The most likely
scenario is that the cable company got a new configuration file for your
modem and neglected to set the upstream bandwith limit before making it
available.

Thank you... very informative... so I guess it's best to sit back and
wait for DOCSIS 2... Oh well... :o)
