TERRIBLE DSL Lite

[themike]

The problem with my DSL is that it laggs, terribly. When im downloading something the DSL always 'freezes' and then continues and freezes etc. I talk over ventrilo servers and have things such as 2K ping, etc. I have removed all spyware from my computer, done virus scans, cleaned my computer, unplugged + re-plugged my modem ALOT of times, and no results. Please help.

:::.. Download Stats ..:::

Connection is:: 216 Kbps about 0.2 Mbps (tested with 2992 kB)

Download Speed is:: 26 kB/s

Tested From:: https://testmy.net (server2)

Test Time:: Sat Feb 11 2006 13:15:38 GMT-0500 (Eastern Standard Time)

Bottom Line:: 4X faster than 56K 1MB download in 39.38 sec

Diagnosis: May need help : running at only 8.51 % of your hosts average (bellsouth.net)

Validation Link:: https://testmy.net/stats/id-U3RHZ601T

This is a new problem, it would never happen to me before and now I lagg ALOT more on games etc.

estimate = 19.65 based on packet size = 11Kbits, RTT = 563.74msec, and loss = 1.0E-6

The theoretical network limit is 19.65 Mbps

The NDT server has a 101.0 KByte buffer which limits the throughput to 1.39 Mbps

Your PC/Workstation has a 15.0 KByte buffer which limits the throughput to 0.21 Mbps

The network based flow control limits the throughput to 0.23 Mbps

Your RTT is rather high. The usual value for the US is 150-250 ms.

Something in your signal line or modem/router is adding to the delay.

Check for possible electromagnetic interference (EMI) on your line or modem/router by other electrical devices, such as sound speakers, cordless phone, TV set, etc.

Keep your modem and router a few feet apart. Are you on wireless?

[themike]

I have my modem ontop of my motherboard on the floor, no i'm not on wireless. My cellphone is in the same room though, aswell as my T.V.

[trogers]

Relocate your modem or raise your modem a foot up away from your motherboard with some books or other insulating material.

[themike]

Ok let me try and draw a picture from you in paint of what it was before and is now.

BEFORE

AFTER

Do you want me to re-test?

[trogers]

Yes do the nitro test again.

[themike]

Do you know of another server like this? This one keeps telling me its busy.

[trogers]

A slight improvement. If you can move your modem aother foot higher it may be better. In the mean time, use this ccs file.

[themike]

I'm not sure if its being affected by my Virus Scan/Spyware scan (the NDT test).

[themike]

Also, forgot to tell you, its on the floor, not higher. Do you mean move it farther away or actually raise it?

[trogers]

Move it further from the motherboard.

[trogers]

Do your speed test with antivirus turned off.

[themike]

Ok. Here is with new css + moved modem.

good morning,

The new position for the modem has turned out to be worse than before. You can see it from the RTT value of the test.

"estimate = 11.17 based on packet size = 11Kbits, RTT = 991.44msec, and loss = 1.0E-6

The theoretical network limit is 11.17 Mbps

The NDT server has a 1088.0 KByte buffer which limits the throughput to 8.57 Mbps

Your PC/Workstation has a 31.0 KByte buffer which limits the throughput to 0.24 Mbps. The network based flow control limits the throughput to 0.25 Mbps"

Try to move it about and then retest by yourself. When your RTT can be less than 300 ms (or even better still less than 200 ms) you will see your PC throughput limit go up from 0.24 to 0.50-0.60 Mbps. This throughput is about the same as your download speed. When RTT becomes lower, download speed will be faster.

I moved modem right next to my modem and heres stats.

[trogers]

Your buffer has been reduced from 31 Kbytes to 17 Kbytes. Did you load a different ccs file?

[themike]

Yes I was testing another one for a second. Here is the highest I can move the modem with your css file.

Where are you located and what is your advertised speed?

If it is 256/128 Kbps, then this buffer of 31 Kbytes is sufficient for you at RTT 488 ms.

[themike]

I'm at Florida. Yes, it is 256/128 Kbs.
