1 edit | [Info] Outlet usage disconnects Modem
 Hello, I have been a member a while but never posted so apologize if I am in the wrong area.
I have a problem and have no idea hot to correct it.
Approximately one month ago, My internet started disconnecting frequently. More and more as summer progressed.
I have found the culprit though now, it is the other outlets in the house.
If I am on the pc and some one plugs in and or turns on a fan in the house (3 different fans all in rooms next to me) it will disconnect my internet cable Modem. How do I keep this from happening and any idea s to why it is happening?
I do not have a surge protector at this time, could that be why the issue?
Thanks for all the help and replies.
Here is my test info: »/tweakr/block:···a=normal |

Ok, Sorry. I had a emergancy here but am back. Here is the info requested sorry wasnt there earlier.
1. Tweaks test (no firewall on)»/tweakr/block:···a=normal
2. The fastest of the 3 speed tests 
Speakeasy test : 848kbps down and 242kbps up
3. A Line Quality test from here. »/testhistory/1263589/5176e
4. Internet connection is Cable and the provider cableonline.com.mx (CableMas) and the Modem is a DCP2100 scientific Atlanta Series (comes with the provider).
5. If DSL, do you use PPPoE connection software? (no idea but I dont think so)
6. N/A
7. operating system is Windows XP Home w SP2 all updates
8. I pay for 1mg service I am not sure of the conversion to kbps
9. No network.
10. no router.
11. How far you are (if using DSL) from the CO (Central Office). Keep in mind that further than 10,000 feet can significantly degrade speeds. Click here to find your distance, or simply ask your ISP" This is wire length, not mileage.
no idea. the office I pay at is aprox 5 miles away and the power pole the line is mainly connected to is 2 block away. with one line to this block with several users. Sorry is not more specific, the site link to hep with that question is currently down.
Also for added info:
Computer is 256 mg with 1.7 gz Celeron Processor HP 503n andd 40 GB HHD |

1: Downloaded DrTcp and set it up accordingly.
2: re-ran tweak test »/tweakr/block:···a=normal
3: Speed Tests from the two DIFFERENT cities nearest me are LA, Calif with 1021 kbps down and 242 kbps up
and San Fransisco with 1016kbps down and 242kbps up
(these look much better i think)
4: On the test download here I get a error message saying I have no access to this ftp server.
So I went to downloads.com here : »www.download.com/WarRock/3000-74···820.html and tried to download this game. It starts at 117kbs then drops to 55 and then slides up to 70 and stablizises in 30-45sec. This is better than yesterday though when I was trying one and it said 20. and another at 50. So is better. But I was downloading at 128 -117 alwaays before, but not now. |

1 edit | On a added note also, I just plugged in the fan and it did not disconnect me earlier and I thought yay! but then this evening I turned it off and .. no internet.
sure don't understand the common denominator between these two things. But sure appreciate the thoughts and ideas. |

| • As for the tweaks and the speed, that is all OK.
• Go to »192.168.100.1. The username is admin and the password is w2402. Post you signals.
• You have some high latency on your line and at your hop. It could be your problem or the ISPs (I see that you are in Mexico.) Ask your ISP to run a ping and line quality check and see what they have to say.
• As for the fan issue, that is not normal. Could be a grounding issue or a dozen other things. I would not not advise that you try to fix it yourself unless you are an electrician. I would ask the ISP to check the line coming into your house and make sure it is grounded properly. If that is not the issue, get an electrician to check it out.

| Just a few simple things you might do:
Perhaps the cable modem is getting too hot due to the warmer temperatures. Or, perhaps, the power-line voltage is lower than normal.
1. Is your cable modem sitting on top of your PC or another heat source?
2. If that is not an issue, try using a fan to cool the modem.
3. Do the lights dim if an appliance is turned on? Ask the electricity provider about the incoming voltage at your home. Has it changed recently due to extra demand on the system? |

Ok, this is the info from that page and thanks so much.
As for the internet providor, We stopped calling them as 9/10 they say it is the pc and it needs to be reformatted or that I have a virus but that it is never thier line....
It doesnt matter if we have connected a new non used pc or several pcs to the line and gotten the same results. That is why I come here so often.  thanks.
Ok, that site did not ask me to log into anything, I have the correct info? 
PS today is one of our days with super heat outside. I will give you the results of the speed test today, looks ok i think.

• Speeds are OK.
• It is possible that the heat is driving the upstream out of spec; however, I don't think this is the case here.

operating system is Windows XP Home w SP2 all updates
Computer is 256 mg with 1.7 gz Celeron Processor HP 503n and 40 GB HHD
Well XP is very slow with 256meg recommend 512 at least if not 1gig.
DCP2100 is a cable modem.... not DSL
'Speakeasy test : 848kbps down and 242kbps up"
That is terrible performance at best so you do have a problem.
Tweaking XP won't fix it, need to find the problem and fix it.
"I pay for 1mg service I am not sure of the conversion to kbps"
242kbps is > .242mbps
kilo = k = 1000
mega = m = 100000
giga = g = 100000000
So 242kbps is 242 / 8 = 30.25 bytes per second or 30.25Bps
Notice the capital "B"
Simple hey...!!!
Sorry.... first grade math.
30.25Bps is Dialup speed.
"no router"
Very bad setup....you need a hardware router of some kind even for one PC...!!
Do you have an old pc w/Pentium III, if so... that may be setup as a router fairly simply.
So from what you have posted so far it looks like you have two problem areas.
A problem with the internet and a problem with power to your system.
So lets start with the internet.
Start > run> type "cmd" enter
ping -n 10 www.google.com
tracert www.google.com
post those results
right click upper left of window and "edit" > "select all"
again right click upper left of window and select "edit" > "copy"
paste that here.
Now for the power.
Turning other equip/devices on/off should not effect your modem and if they
do then that is indicative of a electrical problem.
Find the breaker in your panel that your system is on and feel it to see if it is warm.
Do not open the panel..!!!
Just touch it with your finger on the surface.
If it is warm you may have to many equip/devices on that circuit.
What is the number on the handle of that breaker 15 or 20 ...??
Probably a 15.
If the breaker isn't warm then you may want to consider
having a Electrician look at the wiring in all the outlets on that circuit.
Plug in a lamp to verify you are on the correct breaker and turn off the breaker.
BTW how old is the house and where are you located and there should be
a brand name on the panel somewhere i.e. GE, Murry,Federal...FPE
Then....
download »www.belarc.com/Programs/advisor.exe
install it and
Post ONLY the "Communications" section results here.
Also are you running AV and a software firewall..?? |

4 edits | You are a little late to the party. I told him what his problem was 10 days ago.
I don't know where to start .... Let's try 1st. grade math.
"242kbps is > .242mbps
kilo = k = 1000
mega = m = 100000
giga = g = 100000000
So 242kbps is 242 / 8 = 30.25 bytes per second or 30.25Bps
Notice the capital "B"
Simple hey...!!!
Sorry.... first grade math.
30.25Bps is Dialup speed."
Let's try it the kinder garden way. 242 kilobits/s = 30976 bytes/s
30.25 is kiloBYTES/s
• As far as this speeds are concerned, they are right where they should be. Look at his last speeds test after the tweaking. 985Kb/s = 0.985mb. He is almost hitting his his 1mb cap. Nothing wrong there.
• You are looking at his UPSTREAM and not the DOWNSTREAM. He probably has a 1mb/256kb line. Which is a far cry from dialup.
• As far as playing electrician, I would not recommend that. I asked him to call an electrician to checkout his fan issue.

You are correct I did forget to move the decimal point 242000.
Thanks for the correction.

I would ask the ISP to check the line coming into your house and make sure it is grounded properly. If that is not the issue, get an electrician to check it out." In all my years I've never seen a grounding problem/issue cause the symptoms stated above.
There are millions of houses throughout the US that DO NOT
have the ground wire in them and I have seen many that do
not have the RF cable (cable for Internet & TV)grounding wire.
None of those will exhibit the symptoms stated.
Although it is required to have everything grounded properly
these days it was not required in the past.
Either there is a possible overloading of the circuit or there is a wiring/connection problem on the current carrying conductors (somewhere) causing a transient voltage drop (during load changes)which would cause the modem as well as possible other equip. to reset.
Surely grounding the RF cable per the NEC (National Electric Code) should be checked (and is the responsibility of your service provider) , however it will have no effect on the symptoms reported here.
And like yourself I recommended that a electrician be called to investigate further.
I simply stated a procedure for checking things out which anyone can do and should do, along with checking smoke detectors which are your last line of defense in case of a real problem event.
Also these days there is a handy little tester available called a "Kill A Watt" tester (29.99)which anyone can use that is very inexpensive.

Again any findings using any methods of testing, should be referred to a experienced electrician. |

| First, he lives in Mexico and not the USA. That is why I asked him not to tinker with the stuff. No Idea how they installed the stuff and I am sure they did not use the NEC code.
Second, I am not an electrical by trade, but I have done my share of running electrical wires, installing breaker boxes, and troubleshooting electrical issues.

here is the ping and trace.
and thanks, as far as the elecrician, there is none but me available and yes i live in mexico.
Ok, on the box, there is no heat although it is hotter than haites here right now.
Dusted out the pc, set up a external fan outside pointing to the pc and the modem.
I have no av at this time as it was draining rescources and limiting speed and I needed to see what I actually had. (only has a messenger and front page of yahoo being used anyways, and a game that the wife plays so no surfing really and the disc for av ready when the pc is being used more for school again)
I turned off all auto updates, and firewall. Also the house is 5 years old.
There is some electrical something going on so as it it rented and I can't access it, except what is easily accessable.
This is a cement/stucco and brick house with elect lines in the walls..
I have a question though, on the pc which is 512mg (upgraded) my error sorry, it has a card for wireless installed but is not used. can that be conflicting at all?
Thanks
