[Cable] Flash Speed Test / Denver Server - question(s)

Over the past few weeks I have gotten poor (really poor) download and upload speed results. I'm trying to determine if there is an issue specific to this test/location or if I have a problem with my internet service.

By the way, I'm located on the east coast (Wilmington, DE) and Comcast is my ISP.

I'm using a NetGear WNR3500 router.
My modem is a Motorola Surfboard SB6120.

Some of my tests were done with the router hooked up and some were not. I was trying to see if the router was causing the problem.

Here are the results to the Denver speed test:



As a comparison I also ran a test against the New York and Parsippany servers:



I also ran a test using speedtest.net to their denver server:


Line Quality tests run on several dates (and I know about the west coast test "problem":
»/linequality/nil/2617263
»/linequality/nil/2616605
»/linequality/nil/2616384



The reason why I started running all these tests is that over the past few weeks I have noticed my online gaming experience via my PS3 be impacted by severe lag spikes, some causing a disconnect to the server. I am able to reconnect to a new game but i then experience the same lagging. So ultimately I am trying to ascertain what happened to what use to be a very stable and good performing internet connection.

Any help or ideas would be well appreciated.

Thanks.

Maverick

Can you post a Tweak Test?

Are you playing the games on a wireless connection?

Are you using a "N" NIC on the wireless side?

Yes I'm playing games on my PS3 via a wireless connection. The PS3 doesn't support wireless N so it connects via G.

• You edited your other post where you stated you advertised speeds. I think you said that you upgraded to a 25mb line. Is that correct?

• Try this ......

Download DrTcp

Set Tcp Receive Window to 256960

Set Selective Acks, Path MTU Discovery, Black Hole Detection to Default.

Leave Max Duplicate Acks and TTL Blank

Save/Exit DrTcp

Reboot

Rerun the Tweak Test

Run Two Speed Tests from the two DIFFERENT cities nearest to you that are listed here: Speakeasy POPs

Also, test here »ftp://ftp1.optonline.net/test512

Note your transfer rate after about 30 seconds. Then cancel the download.

Post the URL for the New Tweak Test. For the TWO Speakeasy Tests, Copy and Paste the speed results from those tests and note the speed from the FTP download test.

• I will address the speed issue after you do the above.

My advertised speeds are:

6mbps+Powerboost
Speeds up to 12mbps

Based on this, what number do you recommend I provide in the download speed of the tweaktest?

My current DRTCP settings:
TCPReceive: 128840
Window Scaling: Yes
Time Stamping: No
Selective Acks:Default
Dial Up MTU:1300
PathMTU:Defalut
Black Hole Detection: Default
MTU:1500

With these settings, when I dowload from the FTP URL you provided, the transfer rate fluctuated between 800K-950K. Monitored this for like 30 seconds.

These are DSLReports speed tests:
Speedtest to closest city (Parsippany):

Next closest city (New York)

These are SpeakEasy's:
NewYork:
Download Speed: 21152 kbps (2644 KB/sec transfer rate)
Upload Speed: 3828 kbps (478.5 KB/sec transfer rate)
Washington DC:
Download Speed: 21193 kbps (2649.1 KB/sec transfer rate)
Upload Speed: 4342 kbps (542.8 KB/sec transfer rate)

I can rerun the tests after you tell me what my recommended TCPReceive setting should be based on my advertised speed.

• Much Better. Are those speeds on a wireless connection? If wireless, pull the router and connect directly to the MODEM. Reboot the MODEM and the PC/laptop. Rerun the speed tests.

• Please post the URL for the Tweak Test.

That all looks good.

On your wireless devices, tweak them like the desktop. Test your speeds wireless.

Post the URL for the Tweak Test and the speed tests.

My wireless devices are a PS3 and a Macbook Pro. Do the same tweaks apply?

AFAIK you cannot tweak the PS3. For the Mac see this FAQ »Tweaking FAQ

Outside of that are you happy with your speeds?

Run a new LQT so we can see if there is still packet loss at you hop.

East Coast speeds were never a problem. It was my West Coast speeds that were problematic.

The West Coast is a mess. It is within Comcast network. You have packet loss at your hop. It all starts with this router pos-0-15-0-0-cr01.mclean.va.ibone.comcast.net. There is nada that you can do on your end.

Call Comcast and ask them for a ping test for latency and packet loss. Send the the latest LQT. Lets see what they say.
