You can optimise this setting and others using TCPOptimizer.

Wow, Lamsey, thanks for that one&#33;


Before configuring with this tool my best speed (of 3 tests) was 303.4kb/s. [/b][/quote]
Did you get that at Badwidth Place. I think that site is very inaccurate lol

[Gooch2k]

I got my connection to go up from 515kb/s to 855kb/s so I&#39;m happy&#33; Thanks people&#33;

[Makaveli-tha-don]

how did u know that ur connection went up to 855kb/s.

i need help regarding this tip, i couldnt find TCP/IP in reg and that TCP optimizer would let me make any changes so should i do

[Gooch2k]

I just picked the cable option on TCP optimizer, reset my computer then resarted TCP optimizer and visited Bandwidthplace Speedtest and followed the instructions. I&#39;m now up to 1.1mb/s&#33;&#33;&#33;

Typical latency is the most common problems with broadband connections.
If your ping times are over 100ms set the recieve buffer size to 64240.

If you are suffering from low latency, Ping times under 100ms or your having high ping losses set your receive buffer size to 32120.

If u would like to measure your ping times go to PC Pitstop and run there Ping test
Which measures the round trip time in milliseconds for a packet to travel from your pc to seven other web sites and back.

This will help you figure out the best setting for your connection


Peace brotherdoobie B)

Hmmm, thanks for the tip Brother but it doesn&#39;t seem to have made any difference whatsoever to my connection. I&#39;ve tried both of your recommended TCP Window Sizes (amongst others including the overkill of 999999) and no joy .

By the way I&#39;m not sure that the Bandwidth Place speed test is all that accurate. The test provided by my ISP (plus Net in the UK) suggested that my connection speed was about 480kbps while the Bandwidth place averaged out at about 220kbps. Perhaps I&#39;m being naive and my ISP is lying to make themselves look good but theirs does seem to be the most accurate figure whenever I download direct from the web (AV updates etc.)

3 minutes after restarting my computer my average download speed had a slight jump. Not much though. Thanks for the tip.

i got it finally and those of you didnt know about RegEdit option then follow below instructions and brotherboobie that was nice tip but i am sorry to say that you didnt have cluw what u was talking about.


4 those individuals who still havent solved the problem follow these instructions:

Registry Key: HKEY_LOCAL_MACHINE&#092;SYSTEM&#092;CurrentControlSet&#092;Services&#092;VxD&#092;MSTCP
Value Name: DefaultRcvWindow
Value Type: String Value
Value Data: 64240
Details: has to be a multiple of MSS for best results, i.e. (MaxMTU-40) x number... Best settings to try with MSS=1460 are 64240, 46720 and 23360, in that order




Registry Key: HKEY_LOCAL_MACHINE&#092;System&#092;CurrentControlSet&#092;Services&#092;Class&#092;NetTrans&#092;000n
(Where "000n" is your TCP / IP protocol. It contains "TCP / IP" assigned to the "DriverDesc" Value)

Value Name: MaxMTU
Value Type: String Value
Value Data: 1500
Details: If you&#39;re using DSL and your ISP has implemented PPPoE, you should set MaxMTU to 1492 or less.



Registry Key: HKEY_LOCAL_MACHINE&#092;SYSTEM&#092;CurrentControlSet&#092;Services&#092;VxD&#092;MSTCP
Value Name: DefaultTTL
Value Type: String Value
Value Data: 64
Details: range 1-255, use any number between 32 and 128



Registry Key: HKEY_LOCAL_MACHINE&#092;SYSTEM&#092;CurrentControlSet&#092;Services&#092;VxD&#092;MSTCP
Value Name: PMTUDiscovery
Value Type: String Value
Value Data: 1
Details: Boolean vlue, 0-false or 1-true. Many connections perform better with this entry at 1, however, if you prefer to set your upstream to send fixed 1500 packets, you might want to use 0 instead. When set at 1, establishing connections and initial transfer speed might slow down a bit, however you will get better throughput if somewhere in the path large packets need to be fragmented.


Registry Key: HKEY_LOCAL_MACHINE&#092;SYSTEM&#092;CurrentControlSet&#092;Services&#092;VxD&#092;MSTCP
Value Name: PMTUBlackHoleDetect
Value Type: String Value
Value Data: 0
Details: zero for optimal performance


Registry Key: HKEY_LOCAL_MACHINE&#092;SYSTEM&#092;CurrentControlSet&#092;Services&#092;VxD&#092;MSTCP
Value Name: Tcp1323Opts
Value Type: String Value
Value Data: 1
Details: The possible settings are 0 - No Windowscaling and Timestamp Options, 1 - Window scaling but no Timestamp options, 3 - Window scaling and Time stamp options. The value is documented in RFC 1323. According to Microsoft, Tcp1323Opts should be a DWORD, rather than a string value, however seems that the documentation is incorrect and a string value is necessary to enable large RWIN suppert.


Registry Key: HKEY_LOCAL_MACHINE&#092;SYSTEM&#092;CurrentControlSet&#092;Services&#092;VxD&#092;MSTCP
Value Name: SackOpts
Value Type: String Value
Value Data: 1
Details: Possible settings are 0 - No Sack options or 1 - Sack Option enabled. Selective Acknowledgements are documented in RFC 2018


Registry Key: HKEY_LOCAL_MACHINE&#092;SYSTEM&#092;CurrentControlSet&#092;Services&#092;VXD&#092;MSTCP&#092;Parameters
Value Name: MaxDupAcks
Value Type: DWORD Value
Value Data: 2
Details: taking integer values from 2 to N
