nsomnia Posted January 31, 2006 CID Share Posted January 31, 2006 Ive been getting about 0.6mbit upload to my friend [over msn, same isp] and to testmy.net [We both get that bad speed at this site]. Now, the connection from my ISP to my radio he said was about 2 mbits. Also dslreports.com gets about 1.8mbits. I do have a dlink router is this what is causing this? Any other ideas or testing I should do to figure out why I can only send/receive files from my friend @ 40kb/sec. Quote Link to comment Share on other sites More sharing options...

nsomnia Posted January 31, 2006 Author CID Share Posted January 31, 2006 XP No set speeds. But the tests my ISP did on my radio got 2.5 mbit upload. First test gets 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) = 64240 RWIN Scaling (RFC1323) = 0 bits 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 256960 (MSS x 44 * scale factor of 4) 128480 (MSS x 44 * scale factor of 2) bandwidth * delay product (Note this is not a speed test): Your RcvWindow limits you to: 2569.6 kbps (321.2 KBytes/s) @ 200ms Your RcvWindow limits you to: 1027.84 kbps (128.48 KBytes/s) @ 500ms MTU Discovery (RFC1191) = ON Time to live left = 120 hops TTL value is ok.

nsomnia Posted January 31, 2006 Author CID Share Posted January 31, 2006 It helped a bit, up to about 70kb/sec. But yet no improvments. Maybe your mis-diagnosing. At one site i get my full upload speed. But at this site and on msn they are below 100kb/sec. Quote Link to comment Share on other sites More sharing options...
trogers Posted January 31, 2006 CID Share Posted January 31, 2006 I need to see the test results from http://nitro.ucsc.edu/ Especially the last 2 paragrahs of the "More Details" report. You only posted a section of the summary report. Also do a ping test and post the results click Start/Run and type command and click ok After the c: prompt in the DOS box, type ping www.testmy.net and press enter.

trogers Posted January 31, 2006 CID Share Posted January 31, 2006 From the test reports, your comp is already tweak for a 2 Mbps download speed and I think this is your subscribed speed too. "Your PC/Workstation has a 62.0 KByte buffer which limits the throughput to 6.75 Mbps The network based flow control limits the throughput to 6.90 Mbps" If you had a subscribed speed of up to 6 Mbps, you will be able to achieve at least 5 Mbps in your speed test. Do not forget that heavy traffic will slow you down, especially between 6pm and midnight. To see how slow your network has become, do the nitro test and lookout for "The network based flow control limits the throughput to ___ Mbps" Your download speed most likely will be about 85-90% of this value.
