internet speed problems

[jeepercreeper]

Since yesterday my internet has been extremely slow. When I first called Charter the guy said I had the wrong modem. I upgraded to the 10mb package a few months back and he claimed my modem was only good to 5mb. I took it down to the local office and they gave me a new one but said the old one was good for 10mb too. SO I came home and hooked up the new one, called them back to update the info and such...still slow.

So one of the guys sent me to this site to test the speed:

http://speedtest.net/

Could someone with a good connections please get on there and tell me what your results were so I can compare...

it seems to work fine at times but most of the time I can't get anywhere on any site. They claim there are no outages in my area but I find it hard to believe. I guess they will send a tech out here eventually since after 10 phone calls it still sucks!

First try = down 9529, up 2568 - second test = 10317 down and 2594 up.

it is a Scientific Atlanta DPC1200R2 Cable modem and I have Charter. I have a Mac with Safari for the browser and also another laptop using Internet Explorer and both have the same problem. It is the same using the wireless router or hooked straight from the modem...
Any suggestions would be great

Are you accessing via wireless or Ethernet? If it's wireless, it may be the protocol. 802.11g is currently the most widely used (though not the newest). Its predecessor is 802.11b. The difference between the two protocols is that 802.11b uses Direct Sequence Spread Spectrum and 802.11g uses Orthogonal Frequency Division Multiplexing. The difference between the two is that DSSS breaks the signal up across the entire bandwidth of a channel whereas OFDM breaks it into subcarriers that contain redundant parts of the signal. OFDM is faster because it can send many slower signals in many subcarriers, whereas it is more difficult to send a signal rapidly across the entire bandwidth of a channel as done in DSSS. Now, 802.11g is backwards compatible with 802.11b, but not vise-versa. Therefore, in order for a wireless network to allow two different machines to connect using two different protocols, it must revert to the 802.11b protocol for both.

To test for this as a cause, determine which protocol each machine uses. If one uses 802.11b, disconnect it and refresh your router. It should run faster...

its the same issue if i'm using the wireless router or hook the computer straight to the modem so its not a wireless issue.

Other than hardware, attenuation is the only other culprit.

I did have an issue with water getting inside of the coaxial cable that ran into my house due to a faulty install...

if you can, in the address bar type "http://192.168.100.1" with out "'s of course. You should see a page that looks like:

you are looking for 3 numbers...

1. freq/power or downstream
2. SNR
3. transmit or up stream power

can you list those or take a screen shot and post it.

You guys with cable modems don't realize how lucky you got it. My typical satellite connection is 1500 down, 120 up, and ping times of around 1300, actually not bad as far as satellite goes.

My screen looks nothing like that...

but...

Name: WebSTAR DPC2100R2
Modem Serial Number: 215560889
Cable Modem MAC Address: 00:1c:ea:c1:70:f4
Hardware Version: 2.1
Software Version: v2.0.2r1256-060303
Receive Power Level: -3.7 dBmV
Transmit Power Level: 53.0 dBmV
Cable Modem Status: Operational

[BarneyJeep]

the ranges for you modem are:

Receive Power Level: -3.7 dBmV (this number should be between -10 and +10, with 0 being perfect) you are well within range so that is good.

Transmit Power Level: 53.0 dBmV (max here is 61, but anything over 50 is considered high, although that should still not cause you any problems being a 53)

ok one more thing i would like to see...

goto "Start"
then "RUN"
type "CMD"
hit "ENTER"
type "ping yahoo.com -t"
hit "ENTER"

let that run for five min or so, then

hit "CTRL" and "C" to stop it

i need to know "SENT" (will be a number), "RECEIVED" (also a number), there should also be a "MAX" and a "MIN"

if you dont mind...this is really difficult to do without being there.

*this process is for windows 2k and XP, if you have vista i'll post that process.

*sigh* somebody has to say it Dave, you've just got to use protection with the websites you go to!!

you are correct my friend...

by the way, I have a Mac...

Also, they are sending someone out tomorrow morning to check the lines in the area (supposedly) :rolleyes:
