BIG BIG problems

[lanceifer]

ok where even to begin 

for starters, i have 5 computers 4 are hard wired to a dlink di-624 router of them 1 is xp the others are 2000, and i wireless pc that is running win 2000 also, my modem is a moterolla surfboard supplied by my service provider which is comcast, i have spent  the last 2 months almost every day on the phone with comcast and dlink trying to get this thing running properly, all of the computers are on the internet, but my connection is crap, it is only half what it should be, on any of them, "which makes playing day of defeat source very hard"

i have even tried going direct modem from my  main computer, with no luck it is only marginaly better, i am including all the diagnostic things i can find for you with this so mabee some one who is smarter than me can give me some ideas.

this is download speed  test :

i am sorry if this thing is so long i wanted to get you as much info as i could.

also when i am playing day of defeat source all of a sudden i just get booted saying my ping is to high for the server whay would my ping jump??? or be that eratic when i start my ping is around 35 - 55 then all of a sudden it is at 400??? any ideas???

[lanceifer]

also what is ment by connection limmited and network limited????? and are thies things i can change??????

[trogers]

"The NDT server has a 101.0 KByte buffer which limits the throughput to 8.00 Mbps

Your PC/Workstation has a 62.0 KByte buffer which limits the throughput to 4.97 Mbps

Somehow, the ccs files did not change your PC buffer to 124 Kbyte or 255 Kbyte, thus your throughput is still limited to about 5 Mbps.

I suggest you use the TCP Optimizer as this program can modify your network adaptor.

Download at https://www.speedguide.net/downloads.php

Open the TCP Optimizer and do the following:

Use this ccs file.

Make sure your modem and router are not placed next to each other but are kept separated a few feet apart. Also, ensure they and any signal cables are keep away from sound speakers, phone sets or other electrical devices that may emit electromagnetic interference to your signals.

there is about 3 feet between modem and roughter, and i have them about 4 feet from speakers and 7 from phone the speakers are shilded

Where are you located?

[lanceifer]

coon rapids mn, i have comcast cable

[trogers]

The theoretical network limit is 3.76 Mbps

The NDT server has a 8192.0 KByte buffer which limits the throughput to 493.22 Mbps

Your PC/Workstation has a 125.0 KByte buffer which limits the throughput to 7.52 Mbps

The network based flow control limits the throughput to 7.55 Mbps

As you can see, a RWIN (buffer) of 125 KBytes allow your comp to transmit up to 7.5 Mbps, higher than your 6.6 Mbps subscribed speed.

Your erratic pings levels and your download speed caps seems to suggest that there is some kind of interference in your signals. A problem with the phone line or some other seemingly unlikely source? Last week, we had a guy here whose line was affected by his heat pump located on the other side of the wall.

[lanceifer]

ok when i get home from work to night i will move things around and see how that works, does that all make a diffrence on all the puters in my network????

and is that what is causing my internet to be slow geting on yahoo after boot up??? or if i go from yahoo to testmy.net it takes about 2 mn.  after this last css setting??

[trogers]

Before moving things about, check your phone lines first. Here is a link about checking lines:

In the mean time, use my ccs file - 256960-64240R.ccs in page 1 of this thread.

[lanceifer]

ok i loaded that ccs file it works a lil better, how far away should cordless phone be from my modem roughter and puter???????also thank you for all the help i really apriceate it, i have to go to work now (    i hope you have a great day and i will move things around when i get home tonight once again thanks for all tha help!!!

[trogers]

I would place the cordless phone at the opposite wall.
