What indication do you have that it is losing speed? Could your cable
provider be busy/slow?
 
I'm having a problem with my cable modem loosing speed. The only
solution is to reboot the computer and the modem. Rebooting the modem
doesn't work.

Is this the right newsgroup for this kind of problem?

Try "comp.dcom.modems.cable" but you may want to include a little more info
like cable provider and modem type.

It says contact your cable provider.

I think the question is pretty simple.

What is changing on my broadband connection when I reboot the computer?
What setting is rebooting clearing or changing since the computer reboot
is what returns the connection speed to what it was.

This is usually due to the modem renegotiating it's speed on
a degraded line. It's synchs at full speed on reboot and as
it experiences transmission error it steps down to a lower
speed. It keeps doing this until the transmissions are at an
acceptable error rate.

I run my ISP's speed test so I can see my connection has slowed down.

Did you read my question? I run the speed test, see that my connection
has slowed to a crawl, reboot the modem and the computer and the speed
is back to normal. My ISP says they can't help since rebooting solves
the problem. What connection software is being reset when I reboot?

I use the MSMVP HOSTS file which is rather large but rebooting shouldn't
do anything if that is causing the problem?

That appears to be what it's doing and my ISP isn't going to agree with
that so my solution is to reboot? Not a big deal really, I was just curious.

Is there anything on my computer that would log this?
 
Jim..
I was reading about disabling the DNS Client Services in a different
newsgroup. Mine was not disabled but it is now. May be a couple of days
or more until I can tell if it has fixed my slowdown problem.

Hi JD - Do you have the DNS Client Service disabled? If not, try the
following and see if it fixes your slowdown problem. See here:
http://www.mvps.org/winhelp2002/hosts.htm


"Editors Note: in most cases a large HOSTS file (over 135 kb) tends to slow
down the machine. This only occurs in W2000/XP/Vista. Windows 98 and ME are
not affected.

To resolve this issue (manually) open the "Services Editor"

a.. Start | Run (type) "services.msc" (no quotes)
b.. Scroll down to "DNS Client", Right-click and select: Properties
c.. Click the drop-down arrow for "Startup type"
d.. Select: Manual, or Disabled (recommended) click Apply/Ok and restart.
[more info]
When set to Manual you can see that the above "Service" is not needed
(after a little browsing) by opening the Services Editor again, scroll down
to DNS Client and check the "Status" column. It should be blank, if it was
needed it would show "Started" in that column. There are several Utilities
that can reset the DNS Client for you ... [more info]



Editors Note: The above instructions are intended for a single (home-user)
PC. If your machine is part of a "Domain", check with your IT Dept. before
applying this work-around. This especially applies to Laptop users who
travel or bring their machines home. Make sure to reset the Service (if
needed) prior to connecting (reboot required) to your work Domain ...

JBF sends along this Tip: IPCOP running a DHCP server needs the local PC
DNS Client enabled to function.

Reset the DNS Client with a simple batch file (submitted by: Ronny Ong -
2K/XP only)

DnsManual.bat (resets the DNS Client to Manual) [right-click and select:
Save Target As]
DnsDisabled.bat (resets the DNS Client to Disabled) [right-click and
select: Save Target As]
To use: double-click on the downloaded file and reboot that's it ..."

So call your ISP and have them check the line. Call them when speed
has dropped (because of previous high error rates). Tell them why you
want them to check the line quality. The tech at the other end may
only be able to measure signal strength which is not sufficient to
determine quality, so you may have to schedule a field tech to come
out to your house to measure line quality at the entry point to your
house (they probably are not responsible for anything inside the
house, like cabling to the cable modem, unless you lease their cable
modem).
 
OK, JD - Please do post back with your findings as you monitor this issue.
I strongly suspect this was what was going on based on your description of
the symptoms and your use of the .mvps. HOSTS blocking file. This is
actually a pretty well known issue, and disabling the DNS Client Service is
the usual cure.

I used to go anywhere from 4 to 16 days before I got the slowdown so
I'll post back with what happens in the next two weeks.

I called my ISP and they had me run the speed test in safemode. Since it
ran four times in safemode they said it was my problem and not theirs.
I've called before when the line was not working properly and they told
me to take my computer back to the manufacturer which is me since I
built the computer. A quick call to my neighbor who uses the same ISP
revealed that he also had the same problem and then a quick call back to
the ISP got the line repaired that time. I have a pretty good ISP but
they have pretty bad customer support. The person I talked to didn't
really know what a HOSTS file did.

If you're reading along, I have disabled my DNS Client Service to see if
that fixes the problem.
 
I called my ISP and they had me run the speed test in safemode.

You running a speed test does absolutely NOTHING to check the signal
strength at the cable modem or of checking the qualify of the signal.
You need to have THEM test the signal strength. For signal quality,
THEY will have to send out a field tech to attach their gear to
measure it.

Check transfer rate does not check signal strength or line quality
although it can be affected by them.
 
If I were in your position - and I was in a similar one - I would insist
that the cable company send a tech to check the line going into your house.
I had a similar situation where my signal would degrade until it was lost.
My Motorola modem has five indicator lights, four green which remain steady
and one yellow which flashes to indicate that I'm "online". I could see the
yellow light go off and then the green lights would blink until a connection
was established again, back-and-forth it would go. Tech support said the
modem is bad, replaced it with another that was DOA. Replaced it again and
that one worked but no better than the first. A tech was sent to my home at
my insistence and he found that the signal going into the house was not
strong enough. Strange, for three years since I had the house built, the
dignal was good, now it was weak. The tech put an amplifier on the line and
problem solved - except they tried to charge me for the amplifier.
 
The problem with your suggestion is my problem doesn't happen with any
regularity. It may be two days, it may be three weeks. Since my ISP
feels their signal is strong, if they send out a tech to check the line
and the signal is strong then I have to pay for their tech's visit.

At this point, I'm having success with the DNS service disabled. Time
will tell if that fixed my problem.
 
YW, JD. I'll be interested to see your followup.

Lost my modem speed again this morning. It's been seven days since this
last happened.

The DNS Client Service remains on Manual, it was not started.

I tired just rebooting the modem but that didn't work.

If I reboot the modem and the computer the modem speed is back as strong
as ever. I don't think it's just the signal coming into the modem. There
has to be something that is being reset when I reboot the modem and the
computer?

I did notice that my IP address doesn't change throughout this entire
process. I check it using IPCFG.

Weird, huh?
 
Hi JD - Sorry I didn't get back sooner - Labor Day stuff.

I'm wondering if perhaps you're not seeing DNS server failures. Leave the
DNS Client on Disabled (not Manual) and then try the following:

1. Start|Control Panel|Network Connections then right click on Local
Area Connection and select Properties.

2. Select Internet Protocol (TCP/IP) then click on Properties

3. Click on Use the following DNS Server addresses (this will uncheck
Obtain DNS server address automatically) and then enter 4.2.2.2
and 4.2.2.3 in the Preferred and Alternate DNS server
windows.

3. Now re-boot your machine.


Try this for awhile and see if that solves the problem. (If so, you can
safely just leave them like that permanently without any problem.) Please
post back with your followup again if you will.
