<p>Keep in mind that cable modem speed is heavily impacted by
subscriber count use on your cable leg. 100 users watching tv
is the same bandwidth as 100 users watching netflix or
downloading DVDs. The advantage of dsl is your speed is mostly
constant. With cable it can vary wildly based on your neighbors
activity. Watch your speeds drop when school gets out @ 3pm!</p>

I have had both cable and dsl. With cable, which I currently have, I
notice slow times on weekdays around noon and after school until
about dinner time. Both times are due to heavier use around me.<br>

Hi Sean,<br>
<br>
I'm have Comcast service. I just ran a test at<br>
<a moz-do-not-send="true" href="http://www.speedtest.net"
target="_blank">http://www.speedtest.net</a>. You can use
them but I would stick to speed<br>
testing and not use their PC optimization tests, etc. I got
21 Mbps<br>
down and 4 Mbps up, which is pretty typical for me. Regarding
your last<br>
sentence, the technician should KNOW where to look when he
comes. Once<br>
he's gone, you can do some further testing yourself. One
basic strategy<br>
is to eliminate everything between your PC and the cable
modem. First<br>
make sure you have a software firewall running in your PC. I
would<br>
never recommend connecting a PC DIRECTLY to the internet
without a<br>
firewall running. Take the PC down near the modem if
possible. Turn<br>
off or disconnect any wireless connections. Using the prefab
LAN cable<br>
(as opposed to homemade) that came with the cable modem,
connect the<br>
cable modem DIRECTLY to your PC. Your PC should get an IP
address from<br>
the modem and have direct unfettered access to the internet.
Then, run<br>
your speed test. You may also wish to check that the coaxial
cable<br>
running from the cable modem to the wall outlet is tight on
both ends,<br>
not crimped, etc. Actually, the connectors should be crimped
on, the<br>
wire should not be crimped or severely bent. If the speed
test works<br>
then, you can start moving your PC further away from the
modem. Try<br>
connecting it with a LAN cable to a port on your router.
Then, try<br>
wireless, etc. If, at some point, performance suffers
dramatically, you<br>
may have found the culprit. Be aware that cable internet
performance<br>
will vary depending on how many users in the area are online.
However,<br>
in general, you should get numbers similar to mine if you're
on the same<br>
pricing package. Also, be aware that the speed may drop down
to about<br>
16 Mbps for long downloads and that depends on whether the
remote server<br>
can keep up that speed. I've downloaded many Ubuntu ISO's
where the<br>
remote server could only send 1-2 Mbps and I knew my system
was working<br>
fine. (In that case, find a better mirror server.)<br>
<br>
By the way, I had a scenario once where my download speed was<br>
fluctuating widely and occasionally dropping badly. It took 4
visits<br>
from the techs and me INSISTING that something was wrong.
Finally, they<br>
found a nail had been driven through the cable out on the
power pole.<br>
Depending on the wind, it would either work or not. Once that
was<br>
replaced, everything was fine.<br>
<br>
Hope this helps.<br>
<br>
Sincerely,<br>
<br>
Ron<br>
