Thread: Very Slow DSL Download Speed

    Very Slow DSL Download Speed

    Hi All,

    I'm new here, but not new to DSL. I just recently switched from AOL DSL to Bellsouth FastAcess DSL, only to have displeasure. My download speeds are very slow. At 25/kbps, dial-up download speeds, I'm confused. I was expecting speeds up to 100+/kbps. I'm not sure what the problem is. I searched Bellsouth's DSL page and called, but couldn't find out what is the problem. I'm running Windows XP. I have Spyware and Adware programs installed, thinking it would help some but with no luck. The modem that came with the Bellsouth FastAcess is Westell and I'm running the USB, as I have problems when running the ethernet. I'm not sure what could be wrong, but I'm pretty sure I'll get the help on here to atleast get a download speed of 60/kbps instead of waiting 1 hr. or more for a 100mb download.

    Thanks All for your help.

    TCP properties for IP = 68.214.217.211 ()
    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 = 02040548010303000101080a000000000000000001010402
    MTU = 1392
    MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.
    MSS = 1352
    MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.

    Default Receive Window (RWIN) = 35360
    RWIN Scaling (RFC1323) = 0 bits
    Unscaled Receive Window = 35360

    For optimum performance, consider changing RWIN to a multiple of MSS.
    Other values for RWIN that might work well with your current MTU/MSS:
    519168 (MSS x 48 * scale factor of 8)
    259584 (MSS x 48 * scale factor of 4)
    129792 (MSS x 48 * scale factor of 2)
    64896 (MSS x 48)
    bandwidth * delay product (Note this is not a speed test):

    Your RcvWindow limits you to: 1414.4 kbps (176.8 KBytes/s) @ 200ms

    TTL value is ok.

    take another analyzer test after you do thease settigns your mtu is off

    Try thease in the sg optmizer below me to download and install
    select - cable
    check - custom settings
    network adapter selection -
    check modify all adapters
    maxmtu -1492
    TTL - 64
    TCP Receive Window leave blank
    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 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

    I am having similar trouble with Verizon DSL

    I just moved from my apartment into a house I purchased. The DSL speeds here are VERY slow. Using Verizon's SpeedTest (http://infospeed.verizon.net) I am getting "1x ISDN 64.0K 119.4KBits 14.9KBytes "

    Verizon told me that the problem was my modem after being on the phone for hours and 2 days of Tech's coming out to my place... but, I am using a new modem and still the same problem. I had VERY fast speeds at my apartment. I was downloading files at about 200k per second. Now I am lucking to download at 10k.

    I don't know what to do. Any ideas? Anything else I should check?

    Thank you

    Hi eddieturtle, welcome to our forum. Please start a new thread so that we can assist you exclusively.

    Please let us know who your ISP is and the speed you pay to get.

    What speed are you getting?

    You have just moved into a new house, is the telephone wiring of the house old?

    Also, do and post the TCP Analyzer test.

    So I have the same prblem aslo, but I never had AOL.

    here are the results of the analyzer

    I would double chack you phone bill and find out what the speed package is on your dsl plain.

    i could be wrong that 100mbs is the local speed not the speed of your dsl.

    Reply back with the advertised speed ,and also modem model# we'll get ya fixed

    Im not able to find my bill right now, but I do believe that the dsl speed is 100mbps.

    The router is a Westell Model # E90-610014-06

    Then the router goes into a Linksys Wireless-G Broadband Router Model # WRT54G

    Log into your Westell and go to the section for connection status and tell us what download and upload line speed it is getting from your ISP.

    If your Westell is not set into bridge mode, you are double NAT - 2 routers connected back to back.

    Thumbs up

    Download speeds depend on a variety of factors and that includes the speed of the server from where the file is coming. See these tips to know more
