Using the swedish test I got results as follows: With 5000 file: TCP up 764 kbps and UDP up 791 kbps TCP down 6.33 Mbps and UDP down 6.59 Mbps With 8000 file: TPC up 765 kbps and UDP up 791 kbps TCP down 6.38 Mbps and UDP down 6.59 Mbps That

Here are some results from the tests: cable&dsl 5000: speedguide/UK 1563 DL Testmy.net (smart): 4628 DL

Hello VanBuren, I

Than :)k you very much for your help. I

Here is the dslreport test: http://ttester.broadbandreports.com/tweak/block:3c4742?service=dsl&speed=8000&os=winXP&via=normal My router is a combined dsl-modem and router, one box so I don

I have done all you requested and am back to default. NIC setting was already 100 Bbps full duplex. Speeds with default settings: adslguide.org.uk tested download 609 and 403 (30 minutes later) and upload 285 both times. cemp1.switch.ch tested 1240 and 788 download and upload to 760 both times. As information they suggested a receive buffer of ca. 41.2 kbytes (330kbps) in the first test and ca. 525 kbps in the second. TCP/Web100 Network Diagnostic Tool v5.3.3a click START to begin Checking for Middleboxes . . . . . . . . . . . . . . . . . .

ADSLguide reported on the first try 434 down and 190 up. Then I went to the swiss site and the ersult was 474 down and 546 up. Then I returned to ADSLguide: 177 down and 227 up. Testmy.net gave 371 down and 192 up.

Here is the dsl tweak test. I have done it before without troubles, now it does not report any rcvWindow etc. http://ttester.broadbandreports.com/tweak/block:4bb397b?service=dsl&speed=8000&os=winXP&via=normal I did the same with speedguide: SpeedGuide.net TCP/IP Analyzer TCP properties for IP = 80.223.236.110 () Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322) Notes: Read the Analyzer FAQ if the above is not your IP address. TCP options string = 020405b40103030201010402 MTU = 1500 MTU is fully optimized for broadband. MSS = 1460 Maximum useful data in each packet = 1460, which equals MSS. Default Receive Window (RWIN) = 256960 RWIN Scaling (RFC1323) = 2 bits (scale factor of 4) Unscaled Receive Window = 64240 RWIN is a multiple of MSS Other values for RWIN that might work well with your current MTU/MSS: 513920 (MSS x 44 * scale factor of 128480 (MSS x 44 * scale factor of 2) 64240 (MSS x 44)

I have done the pathping as requsted: (You will learn some Finnish while reading my computer reports!) Microsoft Windows XP [versio 5.1.2600] © Copyright 1985 - 2001 Microsoft Corp. C:Documents and SettingsRalf>pathping testmy.net J

The computer specs are as follows (unfortunately in Finnish language) but you may understand the main points: Win XL home + SP2, Processor 3.2 MHz, Memory 1 G, harddisk 300 G. I have 4 icons visible on the right hand side: network status indicator, Open Office quick start icon, Virus control, Windows messinger. K

Thank you for the advices. I tried them but unfortunately with any success. I think I will be able to improve the speed experimenting with different tweaks but the real problem is that whatever the initial speed is, it goes down dramatically during the Internet session every time! It is even difficult to use the mouse because the arrow hardly is moving. After rebooting everything is initially ok until the same is happening. I have run anti-spy and virus programs and found no problems. Would this sound familiar to somebody please give a hint!
