  1. See if your MTU can be higher than 1480.

    Try the following with the TCP Optmizer (www.speedguide.net):

    General Settings tab:

    Custom settings - check

    Modify All Network Adapters - check

    network adapter selection - your NIC

    MTU 1492

    TTL - 64

    TCP Receive Window -63888

    MTU Discovery - Yes

    Black Hole Detect - No

    Selective Acks - Yes

    Max Duplicate ACKs - 2

    TCP 1323 Options:

    Windows Scaling - uncheck

    Timestamps - uncheck

    Advanced Settings tab:

    Max Connections per Server - 10

    Max Connections per 1.0 Server - 20

    LocalPriority - 5

    Host Priority - 6

    DNSPriority - 7

    NetbtPriority - 8

    Lan Browsing speedup - optimized

    QoS: NonBestEffortLimit - 0

    ToS: DisableUserTOSSetting - 0

    ToS: DefaultTOSValue - 240

    MaxNegativeCacheTtl - 0

    NetFailureCacheTime - 0

    NegativeSOACache Time - 0

    LAN Request Buffer Size - 32768

    Then select "Apply Changes" and reboot to take effect

  2. 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.

  3. 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?

  4. I am not from USA. Can any one please check and see if the signal route of this tracert logical?

    I am troubled by hop 4 into a private IP Address. Could this comp been hacked and signal dirverted?

  5. I think you have a HACKER uploading from your comp.

    Did a check of your Task Manager pic and this is what links in Google showed:

    http://process.networktechs.com/conime.exe.php

    http://www.testmyfirewall.com/dll-files/conime.html

    After reading through further links in Google, there are comments that conime.exe is part of Microsoft.

    I did a check and found it in my c:windowssystem32 (file size 27,648 bytes) but I have never seen this in my Task Manager since using XP. Also, your conime file is shown as 280k in your Task Manager:

    http://s88039565.onlinehome.us/wordpress/archie/2005/02/27/trojan-not-a-trojan-the-story-of-conimeexe/

    http://www.kephyr.com/filedb/index.php?viewtopic=conime.exe+

    http://technet2.microsoft.com/WindowsServer/en/Library/9e1d766f-840c-487a-ace9-72194af2fee61033.mspx

    In conclusion, this exe file seems to be activated when your comp is set work with Japanese, Chinese or Korean languages.

    So if this is true, then conime.exe appearing in your comp may be normal, though the enlarged file size is rather unusual. If you did not run any of these foreign languages, then conime.exe is suspect.

  6. Electromagnetic interference (EMI) can be another possible cause of your speed problem. One common source of EMI is from the router that is placed next to the modem:

    Other sources of EMI are sound speakers (eg. subwoofer) cordless phone set or even the power supply box mounted on the top inside of the CPU tower.

    So ensure you keep your signal cables and signal devices like modem and router away from sources of EMI.
