How come I can not open this website via a WiFi connection?

Maybe I’m missing something easy here, but I am trying to reach http://about.me and get “Unable to Connect” in both Firefox and IE. On a wireless connection to my router which is not blocking the domain. Other laptops on router can access the site, however. I tried blowing up my cache and flushing my DNS. Firewall is turned off. Hosts file is free and clear. Anything I’m missing?

    Maybe I should have been more clear. All other web sites from my laptop work fine, just not http://about.me. The OS is XP SP3. Further, the other laptop which is also on the same wifi connection can reach it while it is Windows 7. And one more interesting note, not a single computer on my university's network can reach it either. I can access it using a proxy, but then the sign up process will not work. So using a proxy I know the site exists. My blackberry can reach it fine as well.

      Jeff,

      what is this about.me website? I cannot open it either.
      I'm using Windows XP SP3 from Canada, by the way.

          Right now it works. It must have been down for a while.

    First which windows OS you are using. Did you tried in safe mode all http and https site and ping

    try edit the hosts file on your LAN clients.

    Hosts: c:windowssysem32driversetchosts
    Open the file HOSTS with Notepad

    add :
    192.168.0.1 webserver-dns-name(your web name!)
    192.168.0.1 must be in concordance of the visited web page

    try DrTCP

    Possible The issue is from the setting called "MTU", which stands for Maximum Transmission Unit, in the network configuration. Install DrTCP
    1)First we need to make sure that the correct network connection or "adapter" is selected
    2)Write down the MTU value you found to start with, and then try these values in order:1492, 576
    3)Save, and then Exit. You will then need to reboot and test to see if the new value has corrected the problem.
    4)if the smaller values don't resolve your problem, then do remember to reset the MTU value to whatever it was when you started

    The "standard" values for MTU are typically:

    •1500: direct connection to an ethernet network, and many broadband connections. As you saw, this is the value my machine uses, connected to my LAN, which in turn is connected to a router and a DSL connection to the internet.

    •1492: certain types of connections (some types of PPPoE) require this value, and if you're having a problem actually related to MTU, there's a high likelihood that this value will in fact work for you.
    •576: the default value for most dial-up connections

    Open Internet Explorer and select Tools make sure that the work off line is not ticked. Also go to Internet Options, Connections, Lan settings and make sure that only the automatically detect settings box is ticked. Check that Proxy server. is not ticked. Also make sure that never dial a connection has a tick.

    Hi, may be you will need to check the network connection from you computer to the router whether has been successful made. Another thing you will need to check is the proxy needed in the browser to access the website. Thanks.

    This may be obvious but: can that computer access the internet at all?
    Also if it makes you feel any better I cannot reach it either.
