    I get the DNS server not responding


    I'm connected to my uni wireless network but i can't access the internet. Everyone else's laptop seems to work fine but mine gives the DNS server not responding error. What could be the problem?

    Have you tried opening Command Prompt and typing: IPCONFIG /FLUSHDNS

    Alternatively, open Control Panel (Small Icons view) > Network/Sharing Centre > Change Adapter Settings > Right-Click your connection > Properties > IPv4/TCP.. (Double-Click) > "Use the following DNS addresses":

    Change the addresses to Google Public DNS Server: 8.8.8.8 and then 8.8.4.4

    Hope this helps,

    Harry

    Do other clients have same dhcp server and dns server? Post output of IPCONFIG/ALL created on a good working machine.

    172.24.8.1 is ip address of router?
    What the hack is 192.168.3.3?

    DNS and DHCP are set to "obtain automatically" now? Sure you did it on the wireless adapter?

    Ping 192.168.3.3 worked, sent 4, received 4, lost 0 but ping 41.204.164.3 sent 4 received 0, lost 4, i tried google dns but it failed the first test of xirrus( dns unreachable). I also set it to "obtain automatically" but to no avail. 192.168.3.3 is one of the network's dns servers
