  1. Hi, my laptop has internet connection from a wifi which works fine. It then shares Internet connection via eathernet to my desktop. Problem is my desktop can only access small websites such as google. I have been told its a packet problem. Anyone know how to fix this?

    Thanks

    hmm; how did you determine this - - someone tell you so?

    Sovling website access is usually a
    1. DNS lookup failure,
    2. an entry in your etc\hosts file or
    3. some hack into your TCP stack.
    let's start with
    #1; get a command prompt and enter these two values
    ping 8.8.8.8
    nslookup google-public-dns-a.google.com
    the first must not timeout; the second should return the ip address 8.8.8.8
    If both work, the TCP is basically sane.

    Test a few well known websites:
    nslookup www.yahoo.com ==>
    Addresses: 2001:4998:f011:1fe::3000
    98.138.252.30
    206.190.36.45
    206.190.36.105
    98.138.253.109​

    nslookup www.google.com ==>
    Addresses: 2404:6800:4005:804::1013
    173.194.127.113
    173.194.127.112
    173.194.127.114
    173.194.127.115
    173.194.127.116​

    nslookup www.techspot.com ==>
    Address: 50.22.252.218​

    If you can get these names to return ip addresses, you're well on your way.

    #2 an entry in your etc\hosts file
    SO, some sites fail?? try NSLOOKUP site_url
    It should return their ip address.

    If fail on the site url, then suspect the etc\hosts file and try this
    (assuming you cant get to wedownloadmanager.com)
    find /I "wedownloadmanager.com" \windows\system32\drivers\etc\hosts​
    I get back:
    ---------- \WINDOWS\SYSTEM32\DRIVERS\ETC\HOSTS
    127.0.0.1 wedownloadmanager.com
    127.0.0.1 www.wedownloadmanager.com
    because I choose to block access to that site
