eddychew Posted June 13, 2005 CID Share Posted June 13, 2005 Was wondering if u can help me in improving my connection in download speed. For your info,i am surfing the net using 3G data card. Have try the hanifv from India method using TCPIP Optimizer but still same result. Appreciate your input! Below are my connection result; TCP options string = 020405b401010402 MTU = 1500 MTU is fully optimized for broadband. MSS = 1460 Maximum useful data in each packet = 1460, which equals MSS. Default Receive Window (RWIN) = 17520 RWIN Scaling (RFC1323) = 0 bits Unscaled Receive Window = 17520 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 256960 (MSS x 44 * scale factor of 4) 128480 (MSS x 44 * scale factor of 2) 64240 (MSS x 44) Quote Link to comment Share on other sites More sharing options...
VanBuren Posted June 13, 2005 CID Share Posted June 13, 2005 hey eddychew and welcome to the forum follow all these steps and post again https://testmy.net/forum/t-2097 install that SP2 p2p fix and also cablenut, let me know what the maximal upload and download speed (advertised) is for your connection VanBuren Quote Link to comment Share on other sites More sharing options...
eddychew Posted June 13, 2005 Author CID Share Posted June 13, 2005 Hi Van Buren, thx for prompt reply. Actually i have tried to follow all the step as stated in https://testmy.net/forum/t-2097,some i skip coz i am not sure. Done the SP2 p2p fix and install cablenut also.THe result shown which i have posted erlier. The advertised speed is 384kbps download and 128kbps upload. Actually it is a 3G using a DataCard connect to Dell notebook for surfing! Quote Link to comment Share on other sites More sharing options...

Hope someone can tell me how to optimize my 3G DataCard connection. Quote Link to comment Share on other sites More sharing options...
FallowEarth Posted June 14, 2005 CID Share Posted June 14, 2005 We need some more info. Take some download and upload tests and post them here. We would also like to know your ISP package (advertised download/upload speeds, type of connection). That will help us out a lot. We will be more than happy to help.

VanBuren Posted June 16, 2005 CID Share Posted June 16, 2005 looks like your maxing out, there is nothing more to do "The network based flow control limits the throughput to 0.15 Mbps" VanBuren Quote Link to comment Share on other sites More sharing options...
eddychew Posted June 16, 2005 Author CID Share Posted June 16, 2005 thx for all the help that u have given. One more thing; could u kindly explain what the statement talking about as shown below; The theoretical network limit is 15.79 Mbps The NDT server has a 255.0 KByte buffer which limits the throughput to 2.83 Mbps Your PC/Workstation has a 48.0 KByte buffer which limits the throughput to 0.53 Mbps The network based flow control limits the throughput to 0.15 Mbps Just wan to understand further on lay man language! hope u don't mind. thx Quote Link to comment Share on other sites More sharing options...
VanBuren Posted June 17, 2005 CID Share Posted June 17, 2005 quote from http://ndt-hc.twaren.net:7123/admin.html "Theoritical Limit - The maximum throughput that a connection could achieve over the end-to-end path. This value is calculated using web100 values for Round-Trip-Time, Packet size, and Packet loss. A properly functioning TCP implementation will never exceed this value. This value does not take the physical network interface speeds into account. This value is meaningful when packet loss rates are large, RTT's are big, or packet sizes are small. Send Buffer - The size, in Bytes, of the NDT server's transmit buffer. Receive Buffer - The size, in Bytes, of the Desktop Clients advertised receive buffer." Network based flow control will show the cap, how its measured i do not know VanBuren Quote Link to comment Share on other sites More sharing options...
