  1. Laptop can't connect to secure networks

    Hi,

    I've got a friends laptop to look at. All of a sudden it stopped
    connecting to various wireless networks. She tried the network card
    in another PC and that was fine.

    I have found that if I turn off WEP security on my router, it will
    connect to my router. But with it enabled, it won't connect. It was
    working a few months ago with security on my router. I've not changed
    my router settings in that time.

    So something has happened to her laptop to stop it working on secure
    networks. I tried re-installing the network card driver and her
    boyfriend ran some "winsock fix" type application to fix corruption
    but that didn't help.

    The PC is running Windows XP, the network card is a DLINK DWL-G650+.
    The router is a cable and Wireless MIMO router. (but the problems
    occur with other routers).

    Any ideas?

    Thanks.

    Peter.

    I think your Friend Laptop Wireless Hardware defer and may be having some
    compatibility issue in some point in the Encryption.
    Do you enter the Encryption Key Phrase into Her Wireless Settings to be able
    to connect?.
    Also try to reconfigured my router to use a HEX pass instead of an ASCII
    string and then try the Connection, does it help?.
    I recommend using WPA encryption method as it is safer than WEP, which
    consider weak by Today's security average.

    Hi
    As said above you have to configure the WEP on the Laptop.
    Some WEP installations would not configured with pass phrase in such case
    you need to copy the HEX string from your Router and paste it to the WEP
    menu of the laptop. See here, http://www.ezlan.net/faq.html#wep
    In addition check the Wireless installation to make sure that it is working.
    May be this can Help, http://www.ezlan.net/wireless.html

    The simplest, most likely, and easiest explanation is that the keys don't
    match.
    Further indication that this is indeed a very good reason is that when you
    convert
    the network to unencrypted, the computer and the router can connect.
    It can be rather tedious to get them to match though. It took me three
    attempts
    to get a WPA-PSK key correctly input.

    Yeah - know what you mean. This is different though as the computer
    used to work with the stored key on my network and is now not working
    no other networks. I'll try out the various suggestions though.

    Thanks.
