Las Vegas, NV | Can you pull the router and connect directly to the MODEM?
Run some speed tests at a local UK site.

Las Vegas, NV | • Could be the router. What kind is it?
• Put the router back in and run the same local speed test test again.
• Might have to up the RWIN.

| In addition test at the local UK site also.
Download DrTcp
Set Tcp Receive Window to 127800
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.

Las Vegas, NV | I don't see anything more in your Tweaks to play with. Maybe a call to your ISP is in order.
Have them check your signals and the line rate settings.

| Thanks for the help Irish Shark I have asked my isp to check what you said so will post up when they e-mail me it seems wierd that my speeds are droping so much, any ways I wanted to ask you how you worked the rwin out was that 9X 1420 =12780
if so why the other 0 as it worked out to 12780 ??? |

| Your original RWIN was 65535. I wanted to push it up 2 times that. 65535 is not and even multiple of 1420 (46.5 times 1420)
So double that is about 90. 1420 * 90 = 127800.

| Your noise margin on the upload is fair. The others are all looking good.
Now since they said that your line is at 5.5mb, what you are getting for speeds is about all you are going to get.
Then next question is why is it 5.5mb and not 8128kb? Ask them why you are not getting 8128ks.

@idnet.net | had word back from isp there said The service is contended at about 50:1 depending on the exchange and time will impact the throughput of your connecting due to other users in your area. |

There is nothing more that you can do.
