Solved I get the DNS server not responding

obby · Sep 5, 2012

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

41.204.164.3
41.89.4.3

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?

Kaktussoft · Sep 5, 2012

Code:

ping 192.168.3.3
ping 41.204.164.3

send 4, received 4, lost 0?

Kaktussoft · Sep 5, 2012

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

obby · Sep 5, 2012

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

Thanks for your posting, I looked at all the gaming social networks on IOS – basically OpenFeint and its competitors – and found catastrophic mismanagement by nearly everyone. The vulnerabilities ranged from de-anonymization, to takeover of the user’s gaming social network account, to the ability to completely take over the user’s Facebook and Twitter accounts using just a UDID.

what has all this got to do with this thread? And anyone who has checked out the whole thread, maybe u have a great idea i haven't thought off. Just anything, even if it has to do with the OS itself

i haven't hardcoded the settings. They are all the same in another's laptop.

Kaktussoft · Sep 5, 2012

Code:

nslookup  [URL="http://www.google.com/"]www.google.com[/URL]  192.168.3.3
nslookup  [URL="http://www.google.com/"]www.google.com[/URL]  41.204.164.3

On working machine it answers succesfully? Or connection refused? Or no answer at all?

Do the same on sick machine
