7Soa7S Posted February 10, 2006 CID Share Posted February 10, 2006 Hello Everyone, I just recently upgraded to a 10/1 cable line in the Tampabay Florida area (RoadRunner). Prior to that I had the 5/384 package and I was able to get a little above that consistently with tweaks (behind the router mentioned below). Here is why I am frustrated with this new package and hoping that I can get some help from the experts Quote Link to comment Share on other sites More sharing options...
trogers Posted February 10, 2006 CID Share Posted February 10, 2006 If you modem and router are close to each other, place them a few feet apart. Then, test your speeds again. Quote Link to comment Share on other sites More sharing options...
7Soa7S Posted February 10, 2006 Author CID Share Posted February 10, 2006 They were about three feet apart and tested again at about 6 feet apart. I am still getting the same speeds... Quote Link to comment Share on other sites More sharing options...
trogers Posted February 10, 2006 CID Share Posted February 10, 2006 Open your ccs file and post the values of DefaultSendWindow - GlobalMaxTcpWindowSize - TcpWindowSize - Quote Link to comment Share on other sites More sharing options...
trogers Posted February 10, 2006 CID Share Posted February 10, 2006 Ok. I got them from the series of numbers you have posted. Here is my ccs file for 10 Mbps - MTU 1500. Quote Link to comment Share on other sites More sharing options...

trogers Posted February 10, 2006 CID Share Posted February 10, 2006 Try with doubling your DefaultReceiveWindow to 513920. Quote Link to comment Share on other sites More sharing options...
7Soa7S Posted February 10, 2006 Author CID Share Posted February 10, 2006 Thank you TRogers, I really appreciate the help.

trogers Posted February 10, 2006 CID Share Posted February 10, 2006 Actually, DefaultWindowSize of 513920 for you is over provided. A 256960 is normally adequate. I gather this opinion from your test results as follows: "The NDT server has a 8192.0 KByte buffer which limits the throughput to 452.96 Mbps. Your PC/Workstation has a 250.0 KByte buffer which limits the throughput to 13.87 Mbps. The network based flow control limits the throughput to 13.95 Mbps" Your PC and the network throughput limits are in balance and both values not higher by much from your subscribed speed. Thus a Tcp buffer (RWIN) of 250 KBytes is adequate. But another part of your test made one significant comment: "There were 78 packets retransmitted, 7 duplicate acks received, and 88 SACK blocks received The connection was idle 0 seconds (0%) of the time This connection is network limited 99.22% of the time." You have quite a high retransmission rate by percentage and something in the network is limiting your speed by 99% of the time." In many such cases, I will first look for line quality problem or electromagnetic interference on the signal processing devices - modem and router.

7Soa7S Posted February 10, 2006 Author CID Share Posted February 10, 2006 That is almost what I was wondering...it is odd though, that for about 4 years I never had this problem and then the minute I upgrade to 10/1 it starts happening.

7Soa7S Posted February 14, 2006 Author CID Share Posted February 14, 2006 Just a follow-up. Had to get a modem replacement and a new router. The modem was capping it at 5, and the router (about 6 years old) only had a 10 connection. Upgraded to a new linksys and getting great speeds. :::..

FallowEarth Posted February 17, 2006 CID Share Posted February 17, 2006 • Using an Ericsson Piperider modem – rented from cable company (same one I was using with 5/384 line) Whup, there's your problem. Call up and get a newer one. Quote Link to comment Share on other sites More sharing options...
