Cable systems do look at the MAC address of the computer,
when you upgraded the computer the hardware MAC changed, but
the modem may still be looking for the old MAC.
Best deal now that prices are lower, get a router to sit
between the cable modem and the computer or computers. Then
you can change or update without that problem, also you can
run and share the cable connection.
| Thanks. I'm answering a couple of replies here.
|
| The modem is about four years old and never been upgraded.
When the
| drop out occurs the lights on the modem indicate
connectivity, same
| with the ethernet card. I have had the cable outdoors go
bad a couple
| of times. Once a squirrel apparently ate through the
insulation.
| Another time water got into the splitter, froze, and broke
the
| splitter apart. After they were fixed, everything worked
fine. The
| thing this time is the timing. One night, on my old
system, all was
| fine. The next day, I built the new system, hooked up, and
the problem
| started. That's why I figured it was with the new system
somehow.
| Hardware, software, whatever. Maybe it was just
coincidence, as much
| as I don't believe in coincidence. Also, here's a post I
just made to
| a cable related group. Maybe it's pertinent:

| ----------------------------------------------------------
-------------------------------------------------
| I've been having problems since building a new system last
month:
|
| ASUS P4C800 Deluxe board
| 1Gb RAM
| Windows XP Pro
| Intel 3.2Ghz processor
|
| I use Optimum Online cable modem service.
|
| Since building the new system, my connection drops out
several times a
| day. Never while I'm actually doing something, but if I go
from one
| program to another, i.e. Agent to Netscape or AOL,
suddenly the
| connection is gone and I have to reboot to get it back
(release/renew
| doesn't work).
|
| While checking the modem, I noticed two attenuators hooked
up in line.
| I then remembered the cable tech putting them there about
two years
| ago for a problem I had back then on a different system. I
don't even
| remember what the problem was. The attenuators say 6dB and
3dB. I took
| them off to see what would happen. So far my speeds seem
good. I
| haven;t lost the connection yet, but then it's sporadic at
best, and I
| could lose it after posting this note.
|
| My question is what are these attenuators, and what do
they do? And do
| I need them? Thanks for any help.
