    really slow download, but really fast upload

    Hi,
    I just got Verizon DSL today. Being used to cable I was expecting somewhat similar speed. Upon surfing the web I noticed that the speed was similar/slower than my dial up. So I went over to www.dslreports.com to do a speed test. The result was very strange. The download speed was 24 kbps, while the upload was 258 kbps. I cleared cache and tried a few times more. The results were still similar. Then I applied the tcp optimizer which I have used before when I had cable. So I was hoping it would "fix" the problem. So I selected optimal setting for DSL (PPPoE). However the results were the same.
    Does anyone have any ideas whats going on?
    Thanks in advance.

    Welcome to Speedguide, please read here so that we can properly help you. You need read ALL of it so that you have a basic understanding of what you are trying to accomplish. You MUST answer ALL 5 questions at the top so that we can properly help you.

    P.S. Remember to XXXX out your IP address from the TCP/IP Analyzer.

    Verizon DSL. I dunno the advertised speed but I assume its DSL default speed. The Url is www.verizon.net

    SpeedGuide.net TCP/IP Analyzer


    TCP properties for IP = xxx.xx.x.xx (pool-138-88-9-22.res.east.verizon.net)
    Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705)
    Note: Read the Analyzer FAQ if the above is not your IP address.


    TCP options string = 020405a001010402
    MTU = 1480
    MTU is optimized for Windows XP PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.
    MSS = 1440
    MSS is optimized for Windows XP PPPoE DSL broadband. If not, consider raising MTU to 1500 for maximum throughput.

    Default Receive Window (RWIN) = 17280
    RWIN Scaling (RFC1323) = 0 bits
    Unscaled Receive Window = 17280

    RWIN is a multiple of MSS
    Other values for RWIN that might work well with your current MTU/MSS:
    506880 (MSS x 44 * scale factor of 8)
    253440 (MSS x 44 * scale factor of 4)
    126720 (MSS x 44 * scale factor of 2)
    63360 (MSS x 44)
    bandwidth * delay product:

    Your RcvWindow limits you to: 691.2 kbps (86.4 KBytes/s) @ 200ms
    Your RcvWindow limits you to: 276.48 kbps (34.56 KBytes/s) @ 500ms
    Consider increasing your RWIN value to optimize TCP/IP for broadband.
    MTU Discovery (RFC1191) = ON
    Time to live left = 120 hops

    TTL value is ok.
    Timestamps (RFC1323) = OFF
    Selective Acknowledgements (RFC2018) = ON
    IP type of service field (RFC1349) = 11101000

    Precedence (priority) = 000 (routine)
    Delay = 1 (low delay)
    Throughput = 0 (normal throughput)
    Reliability = 1 (high reliability)
    Cost = 1 (low cost)

    I guess no one knows
    I'll just call their tech suppt and wait for hours.
    One thing though, does any one knows how I can remove that god awful "customized for Verizon Online" thing on IE6 title bar?
    Thanks in advance.

    Your settings look fine, try the following:

    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. 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 & Ad Aware 6.0 to remove any spyware then install and update SpywareBlaster 1.2 to stay spyware FREE. It is an ABSOLUTE MUST that you use BOTH Ad Aware 6.0 & SpyBot 1.2, don't think you are safe with just one of these apps since one will find what the other misses.

    7. Make sure you do the faster web page tweak in my Help & Tips link.
