    I use IE7 going through a router to the internet. About 1 week ago IE was
    not opening some websites at all and others would take a very long time to
    open (more than a minute).

    I hooked up my computer directly to my cable modem and everyhting worked
    great. When I go through the router I have my problem .

    There is one other computer that is wired to the router and they work fine.
    I have 2 laptops that connect to the internet with WIFI through the router
    and they don't have a problem. Only my computer that is running XP Pro SP3.

    I have looked at all settings and I can't see anything wrong.

    Before I reload windows XP or install Vista in hopes that the problme would
    go away I am looking for some help from the community

    You should list the settings for both of the wired computers. It would be a
    good idea to list the settings for the wireless ones as well.
    If we don't have these settings, we are flying blind.

    And, are you running IE7 with addons?

    If computers "A" "B" and "C" are all attached to the router by a
    wireless connection, and only computer "A" has slow browsing: If
    clearing TIF on computer "A" does not restore web browsing to its
    typical speed there are many possible causes, among them:

    1- Computer "A" has been hacked.
    2- Software installed on Computer "A" - typically some flavor of
    security software - is interfering.

    Please let me know which settings do you need to know about?

    I have one LAN connection that is set to find the the IP address
    automatically. The IP address is When I try and go to my router
    set up, the main screen opens and then when I try to view the carious
    settings and opitons it freezes.

    I am not running IE7 with addons

    Computer A & B are coneected via ethernet. Computer C&D are wireless. B, C,
    & D connect and surf with no problems. Computer A has no problems surfing
    the internet when it is connected directly to the modem. Computer has an
    obvious problem when it is connected to the router. I changed the ethernet
    cable. I think it has to do with the configuration of the LAN connection
    properties and some conflict with the router.

    I have tried many combinations of things to change the LAN connectin
    proerties but nothing is working. Is there any way to delete the the LAN
    connection and create a new one?

    The ones reported by ipconfig/all. It would be helpful to create this list
    on all of your computers.
    Is the address of therouter at
    Can you get to the router from any of the other computers?
    If you shutdown the other computers, can you then get to the router from the
    problem computer?
    It could be that the there is an ip address conflict in your LAN.

  7. Recreating the LAN connection is unlikely to fix anything unless you had
    previously adjusted settings specific to your network card.

    Have you at any time in the past on this PC adjusted any settings related to
    MTU or Checksum Offload? Both of these are often cited as ways of improving
    performance, but with the wrong settings can actually cause more problems.

    Disabling Checksum Offload is worth a try if you haven't already done so
    (not all network chipsets have this, but on the few PCs I've had the
    experience of tinkering with turning this off was a vast improvement with
    connection stability). What this setting does is to use the network chipset
    hardware to calculate packet checksums, and some of these chipsets actually
    get the calcs wrong forcing the network layer to have to retry repeatedly
    until packets can be sent correctly.

    For MTU you would need to ensure that your MTU setting is reverted to the
    Windows default or set to a value matching the router - it's possible that
    this may have been adjusted to match the modem so it performs fine when
    corrected directly, but the router may have a different setting and while it
    can negotiate changes to this to send to the router having your PC send in
    mismatched packet sizes could be causing the router to ignore those packets
    or respond in a way to get your network driver to adjust it's size, and if
    the driver is buggy this might well be happening on every packet instead of
    the first ones to be sent to the router.

  8. Did the “ XP Pro SP3 †computer stop working after
    you installed SP3 ? If so, do a System Restore to get rid of it.

    Recently, my modem disappeared after intalling Vista-32 SP1
    because, for some unKnown reason, I don't have privileges to run
    the “ Secure Socket Tunneling Protocol †service.
