    Question Help in tweaking GWI dsl.


    I just jumped over to GWI (3000/784) from Verizon (1500/384). Since both are $40/month, it seemed a good move.

    I need help in tweaking Cable Nut.

    MTU = 1500
    MTU is fully optimized for broadband.
    MSS = 1460
    Maximum useful data in each packet = 1460, which equals MSS.
    Default TCP Receive Window (RWIN) = 513920
    RWIN Scaling (RFC1323) = 3 bits (scale factor of 6)
    Unscaled TCP Receive Window = 64240

    RWIN is a multiple of MSS
    Other RWIN values that might work well with your current MTU/MSS:
    513920 (MSS x 44 * scale factor of 8) <-- current value
    256960 (MSS x 44 * scale factor of 4)
    128480 (MSS x 44 * scale factor of 2)
    64240 (MSS x 44)
    bandwidth * delay product (Note this is not a speed test):

    Your TCP Window limits you to: 20556.8 kbps (2569.6 KBytes/s) @ 200ms
    Your TCP Window limits you to: 8222.72 kbps (1027.84 KBytes/s) @ 500ms
    MTU Discovery (RFC1191) = ON
    Time to live left = 51 hops
    TTL value is ok.
    Timestamps (RFC1323) = OFF
    Selective Acknowledgements (RFC2018) = ON
    IP type of service field (RFC1349) = 01011100 (92)

    Thanks for your help.
    E2200 Allendale @ 3160
    10 x 316mhz
    MSI 7345

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

    General Settings tab:
    Custom settings - check
    Modify All Network Adapters - check
    network adapter selection - your NIC
    MTU - 1500
    TTL - 64
    TCP Receive Window - 64240
    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

    1. Under your LAN connection - properties - general tab, uninstall all the protocols there that you do not need. For a stand alone pc all you need is Internet Protocol TCP/IP.
    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 and set your duplex mode to "auto". If you are using a router make sure you have the latest firmware.
    4. Clean out your temporary internet files with CrapCleaner.
    5. Power cycle your modem i.e. unplug it for at least 15 seconds.
    6. Download, update and scan with SpyBot S&D 1.4 EXACTLY as mnosteele has explained HERE & Ad-Aware SE 1.06 EXACTLY as mnosteele has explained HERE to remove any spyware then install and update SpywareBlaster 3.4 to stay spyware FREE. YOU MUST USE BOTH AD AWARE & SPYBOT TO ENSURE YOU ARE SPYWARE FREE SINCE ONE FINDS WHAT THE OTHER MISSES. If these 2 programs find a lot of things then please post a HijackThis 1.99.1 log for us to look at.
    7. Make sure you do the faster web page tweak in our Help & Tips page.
    8. If you have Zone Alarm as a firewall uninstall it and search your pc for the left over files.
    9. Install Kerio Personal Firewall 2.1.5, it's FREE and uses next to no resources.
    10. Do a FREE online virus scan from Kaspersky Webscan, make sure to check the option to use the EXTENDED DATABASE.
    11. Make sure you have ALL of the latest Windows Updates.
