    Just switched from TCP Optimizer to CableNut Please help with settings.

    SpeedGuide.net TCP/IP Analyzer


    TCP properties for IP = 70.25.19.18 ()
    Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)
    Notes: Read the Analyzer FAQ if the above is not your IP address.

    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 8)
    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 = 56 hops

    TTL value is ok.
    Timestamps (RFC1323) = OFF
    Selective Acknowledgements (RFC2018) = ON
    IP type of service field (RFC1349) = 00000000





    16628122 connections tested since 03.10.2001.
    Analyzer version: 1.05 - updated 08.14.2003.

    Using XP Pro ...can you please advise on which settings to use in CableNut as I an a first time user. I am using SB1500 Surfboard Modem and was getting a d/l speed of 1.8 MB/sec. Rather ****ty as I have a 5Mb d/l rating on this modem. Using Rogers Extreme internet service with advertised download of 5MB and upload of 800 KB. Thank you in advance for your time.
    Cheers.

    1. Under your LAN connection - properties - general tab, uninstall all the protocols there that you do not need.

    2. Open IE and select tools - internet options - connections -
    LAN settings, make sure NOTHING there is checked.

    3. ALWAYS connect your modem via ethernet (NIC) and make sure you have the latest drivers for your NIC from the manufacturer. Set your NIC duplex mode to 10mb half duplex for Cable, for DSL it is ISP dependent unless you are using a router, if so then set it to 100mb full duplex for both Cable & DSL (the instructions are in my Help & Tips link). If you are using a router make sure you have the latest firmware.

    4. Clear your temporary internet files.

    5. Power cycle your modem, unplug it for atleast 15 seconds.

    6. Download and update then do a scan with SpyBot 1.2 http://beam.to/spybotsd & Ad Aware 6.0 http://www.lavasoftusa.com/support/download to remove any spyware then install and update SpywareBlaster to stay spyware FREE. YOU MUST USE BOTH AD AWARE & SPYBOT TO ENSURE YOU ARE SPYWARE FREE SINCE ONE FINDS WHAT THE OTHER MISSES.

    7. Make sure you do the faster web page tweak in Read1st link.

    8. If you have Zone Alarm as a firewall uninstall it then visit Zonelabs.com for further instructions on removing it's left over junk.

    9. Install Outpost Firewall http://www.agnitum.com\ or Sygate Firewall http://www.sygate.com/ , both have FREE and Pro versions and are heads above ZA.

    10. Scan for viruses with your antivirus app, if you do not have one get one IMMEDIATELY, AVG 6.0 http://www.grisoft.com/us/us_dwnl_free.php is an excellent FREE AV app.

    11. Make sure you have ALL of the latest Windows Updates

    mccoffe,
    Thank you for the numbers. I am now getting much better speeds with cablenut than with the optimizer. Did a speed test through www.coegco.com with your #'s...
    d/l 4662 KB u/l 790 KB.@578KB/s ...TCP Window size-64240
    I increased my TCP Window Size to 128480 and retested : d/l 4677 u/l 789 KB @ 584.7KB/S. A 46 KB increase in download speed.I see people getting in the upper 4800's @ broadbandreports.com Very curious to know if I can improve my speeds. Any suggestions to other numbers other than u mentioned. I have used all your other suggestions as well. Thank you . Cheers!!
