    Question Cable speeds just not up to par

    I recently changed my cable ISP to a much smaller company, DCCNET, based out of Delta BC, Canada. Not sure of the advertised speeds, but after applying the speed patches and running the optimizer through it's process, things seemed alright. But once I began downloading with a newsgroup downloader (will leave program name out for obvious reasons), my speeds slowed to a crawl (34 KB/sec.), just hoped someone here could lead me in the right direction to speeding this up. I am behind a Linksys router, and running windows XP.

    Here are my analyzer results:

    TCP options string = 020405b40103030201010402
    MTU = 1500
    MTU is fully optimized for broadband.
    MSS = 1460
    Maximum useful data in each packet = 1460, which equals MSS.

    Default Receive Window (RWIN) = 256960
    RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
    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)
    128480 (MSS x 44 * scale factor of 2)
    64240 (MSS x 44)
    bandwidth * delay product (Note this is not a speed test):

    Your RcvWindow limits you to: 10278.4 kbps (1284.8 KBytes/s) @ 200ms
    Your RcvWindow limits you to: 4111.36 kbps (513.92 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 (0)


    I appreciate any help I can get.
    Thanks in advance, you guys are great! =)

    Try thease in the sg optmizer below me to download and install


    check - custom settings
    network adapter selection -
    check modify all adapters
    maxmtu 1500
    TTL - 64
    TCP Receive Window 64240
    MTU Discovery - yes
    Black Hole Detect - no
    Selective Acks - yes
    Max Dup ACKs - 2
    TCP 1323 windows scailing is checked

    Other Settings tab:

    Max Connections per Server - 10
    Max Connections per 1.0 Server - 20
    Lan Browsing Speedup - optimized

    Then select "Apply Changes" and reboot to take effect.



    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 http://beam.to/spybotsd & Ad Aware 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
