    Hi all,
    This is my first post here, and want some advise about what could be causing slowing my laptop for browsing.

    I am using a HP pavilion with Vista. I recently moved to a new state, and even though speedtests (using speedtest.net download ~11Mb/S, upload 2Mb/s, latency 22ms) show similar results as the speed test results at my old house, internet browsing using my browser (mozilla firefox) has turned very slow. Anytime I click on any website it shows a blank page for about 5-10sec and then sometimes slowly loads it, or sometime shows a page saying "problem loading page". This never happened at my old house and I seldom had slowdowns in browsing.

    Here are the specs:
    - comcast service provider.
    - it is not due to spyware malware. i have strong security on my laptop with no malware that i know of.
    - HP pavilion laptop, intel processor, vista.
    - cleaned cache, all temporary internet files removed using Norton software, and also from mozilla browser.
    - Am connecting directly to motorola modem using a cat 5 line.
    - comcast package promises upto 20Mb/s download speed, and it is same as my old house.

    Any ideas about what could be causing it?

    Here is what the screen shows with "problem loading page"
    ----
    Server not found

    Firefox can't find the server at global.ard.yahoo.com.


    * Check the address for typing errors such as
    ww.example.com instead of
    www.example.com

    * If you are unable to load any pages, check your computer's network
    connection.

    * If your computer or network is protected by a firewall or proxy, make sure
    that Firefox is permitted to access the Web.

    I am not using the google DNS. I do not see any significant difference though - web pages still are loading very slowly, and sometimes lead to "problem loading webpage" screen. Sites like youtube or cnn videos that used to run promptly when clicked are taking minutes to load and intermittently wait for buffering of video.
    Since the internet speed using speedtest.net as reported earlier is fairly same as my old apartment, I have no clue what is going on.

    Please help!

    Having been on Google DNS for a few days I just tested the speeds again as the problem with slow internet still exists. Speedtest.net shows 14Mb/s upload, 4 Mb/s download, 25ms ping. However, pingtest.net shows - 55ms ping, Packet loss of 70%, and jitter of 120ms. The same sites rates my internet F (lowest grade).

    How could this be happening?

    I called Comcast tech support and they say your modem shows no packet loss and that internet is good. (I have found it futile to talk with them about my internet issues).

    Get PingPlotter
    http://www.pingplotter.com/featurecomp.html

    You can ping and get a trace that will show packet loss.

    They have the free version also at the bottom of the page here and I use it and love it and I also had trouble with Comcast when I moved here and I took lots of screen shots of all the pings to lots of sites to show them. Had odd troubles because was after about 8 pm but could go on for 10 to 12 hours. It got so slow that it was down to dial up speeds and took some time for them to get it fixed. So not sure what I should them helped to fix things but it did show I was having trouble. Also had a new PC so had 2 PC's

    http://www.pingplotter.com/download.html

    Also do the ping test at http://www.pingtest.net that you can also get to from http://www.speedtest.net

    Do not understand all the info it gives but you can do a test here.
    http://netalyzr.icsi.berkeley.edu/

    Also do this one.
    http://www.whichvoip.com/voip/speed_test/ppspeed.html

    This is one you have to install that tells a lot at first but then if you got the free version it will be more limited but still gives some good info.
    http://www.myconnectionpc.com/liteexpired.html

    As you can see from the name in the link "liteexpired" it is the lite or free version and it stops working every now and then and will no open and it tells you to get the newer version. Need Sun Jave to make it work.

    I think and have read that java test are better then the flash test.

    The "Round trip time (min) is 27 ms" and shows red so that is not so good for me but the rest looks good.
    Summary of application test results
    Download speed 21333 Kbps
    Upload speed 4422 Kbps
    Quality of service 75 %
    Round trip time (min) 27 ms
    Max delay 21 ms
    Bandwidth 72800 Kbps
    Timer accuracy 1 ms

    Do not know if your be able to see this or not because it is from a link I clicked on.
