Diagnosis: DEFINATELY need help

Recommended Posts

Hello All

I have a Free Computer Help site and several users have been posting their results from your site at my site in this thread:

http://www.cpfools.com/forum/showthread.php?t=2016

So I thought I'd come over to see what the fuss was about.

I tested my work account and not bad, but when I checked my Verizon home acount on DSL...... OMG what crap!

Any suggestions would be great if you all could help!

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

Connection is:: 738 Kbps about 0.7 Mbps (tested with 748 kB)

Download Speed is:: 90 kB/s

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

Test Time:: Tue Feb 7 19:41:09 PST 2006

Bottom Line:: 13X faster than 56K 1MB download in 11.38 sec

Diagnosis: May need help : running at only 15.66 % of your hosts average (verizon.net)

Validation Link:: https://testmy.net/stats/id-FTER8GOIN

Also:

My guess would be that these stats are for a 768 Kbps/ connection

https://testmy.net/personal_stats_30d.php?user_name=CP&m=02&d=07&Y=2006

I really need some good advice for this crap DSL speed.

I am using Verizon's Westell WireSpeed DSL modem and nothing running but Outlook, Zone Alarm and Kaspersky AV 5.0 at time of test.

I turned off Zone Alarm and got the same results:

When you need help please add these things into your post:

What OS (operating system) are you running? XP SP2 with ALL patches.

What service do you have and what is the advertised speed for download/upload. Unk

Which tweak programs have you already installed and run this test:

http://www.dslreports.com/tweaks (copy and paste the result (URL) address in your post) NO "tweaks", I wanted a fresh test. Are you saying I should run tweaks?

What speed do you get? http://www.testmy.net/

Also download this Tracert and Ping program (made by PHP)

Go to www.cablenut.com and download the Cablenut Adjuster program. Use this program to open the ccs file attached below. Then, click 'Save to Registry', exit and reboot your comp.

Do your speedtests again to compare before and after speed results.

I just downloaded the file you attached because I downloaded Speed Nut program and added the file to my registry. I then tested my speeds and .... they were slower:

This is the key to the problem:

"Web100 reports the Round trip time = 1195.11 msec; the Packet size = 1460 Bytes; and No packet loss was observed.

This connection is receiver limited 85.85% of the time.

  Increasing the the client's receive buffer (125.0 KB) will improve performance

This connection is network limited 14.12% of the time."

Something at your end (receiver) is limiting speed. This can be seen by the RTT value of 1195 ms. Under normal conditions, RTT (round trip time) should not exceed 300 ms if you are in USA.

In many such cases, I will first look for line quality problem or electromagnetic interference on the signal processing devices - modem and router. Here are some interesting links of other people's experiences:

https://www.speedguide.net/read_articles.php?id=1885 I do not have a router

https://www.speedguide.net/read_articles.php?id=117 PC Subwoofer off during tests and I do notown a cable modem. It is DSL.

I called Verizon to do a line check 3 weeks ago and line check came back clean.

Any other electrical devices near your comp that emits EMI? A subwoofer has a hugh magnet within its casing. Even with power off, there is still magnetic effect. Keep it away from your modem and signal cables. Any other devices like cordless phone etc.?

No other devices what so ever. I just moved my modem from above my sub wolfer to down under my desk. I'll run the test again and post results of site you wanted details on and my http://www.dslreports.com line test results as well.
