bellazdad Posted February 21, 2006 CID Share Posted February 21, 2006 Can't get Download speed off of testmy.net, only Upload. Using other speedometers of bandwidth (pcpitstop.com), I am showing a severely crippled connection. Using WinXP, SBC DSL (not the Pro-pack). Where do I start with this? Here what I know: Bandwidth Down: [glow=red,2,300]133 Kbits/sec [/glow] Bandwidth Up: 322 Kbits/sec Average Ping: 99 ms Ping Loss: 0% TCP Receive Window (default) Browser MSIE 6.0; SV1; .NET CLR 1.0.3705 IE current cache 13 MB IE max cache 80 MB Here's what I have done: Power cycled; Run TCPOptimizer; Run AdAware; Run Search and Destroy; Run CCleaner. I have a current HijackThis file (for those that can help with that) Still very sluggish.... Any suggestions? Let me kow what esle I can do to help my speed. Many thanks in advance.

trogers Posted February 22, 2006 CID Share Posted February 22, 2006 The following parts of the test results are of significant: "There were 12 packets retransmitted, 45 duplicate acks received, and 50 SACK blocks received The connection was idle 0 seconds (0%) of the time This connection is network limited 99.98% of the time. Excessive packet loss is impacting your performance, check the auto-negotiate function on your local PC and network switch RTT = 178.93msec MaxRwinRcvd: 33396 Your PC/Workstation has a 32.0 KByte buffer which limits the throughput to 1.42 Mbps The network based flow control limits the throughput to 0.43 Mbps" Your signal quality is not good as shown by the high RTT and packet losses. Your RWIN (buffer) is only 33396 limiting your throughput to 1.4 Mbps. Your ISP network at the time of testing has high traffic shown by the small throughput of 0.43 Mbps allocated to you. To check line quality, do a tracert to www.testmy.net What is your ISP advertised speed? Quote Link to comment Share on other sites More sharing options...
bellazdad Posted February 22, 2006 Author CID Share Posted February 22, 2006 I will admit that most of what you said is over my head.... What is a tracert and where exactly can I find one on testmy.net can. If that is done during the "Download Speed Test", here are the results: This was tested from a 1075 kB file and was downloaded in 30.64 seconds :::.. Download Stats ..::: Connection is:: 287 Kbps about 0.3 Mbps (tested with 1075 kB) Download Speed is:: 35 kB/s Tested From:: https://testmy.net Test Time:: Bottom Line:: 5X faster than 56K 1MB download in 29.26 sec Diagnosis: May need help : running at only 66.44 % of your hosts average (232.51) Validation Link:: https://testmy.net/stats/id-DF38TOQJ5 My ISP advertised speed is up to 128 to 384Kbps. (Only speed available in my area). Quote Link to comment Share on other sites More sharing options...
trogers Posted February 22, 2006 CID Share Posted February 22, 2006 To do a tracert, click 'Start' and then 'Run'. Type "cmd" into the box and click 'ok'. A DOS black screen will appear. Type after the C: tracert www.testmy.net and press enter key When test is completed, move mouse cusor to the DOS black screen, click right and choose 'select all'. Move mouse cursor to the Quick Reply box of this forum, click right and 'paste'. Quote Link to comment Share on other sites More sharing options...

trogers Posted February 22, 2006 CID Share Posted February 22, 2006 Are you located far from your ISP's CO? Hop 2 to 3 sees a big delay. Another possibility is problem in the telephone lines Check visually that the phone line within your home is okay right to the junction box located just outside the house and that there is no electromagnetic interference (EMI) from nearby electrical devices affecting the low voltage signals in the line. We had a case a couple of weeks ago, where a defective heat pump was emitting strong EMI affecting signals. Quote Link to comment Share on other sites More sharing options...
