DNS server not responding?

#1
Hello

I have a router which is connected to a desktop (not wireless) and a laptop which is connected wireless.
On my laptop, i have internet, i have connections, i can browse the internet, but my computer says this :

Your computer appears to be correctly configured, but the device or resource (DNS server) is not responding.

when i connect to the wireless internet, my laptop seems to be connecting, but taking longer than usual.

How do i fix this?

i have flushed the dns cache, and disabled IPv6

When connected through a router (either wired or wirelessly) the DNS server address should be set to the router address. This should be done automatically if dns server address setting are set to automatic for each of the adapters concerned. You can check the dns server address for each of them by going to command prompt and enntering:

ipconfig /all

If you would like any help interpreting the output please post the report on here.

My desktop computer's adapter setting is manual
and my laptop setting is automatic,
which ipconfig /all do you need?

This is my laptop's :

The DNS server address on your wireless connection is causing the problem:

DNS Servers . . . . . . . . . . . : 24.201.245.77

It should be set to 192.168.1.1 (the address of your router - the router will then forward dns requests to the real dns server address from your service provider). You can either change this manually or (if the is no special reason for having manual settings) you could change the wireless adapter to obtain all addresses (IP address and dns server address) automatically.

i dont have much knowledge about computers,
so i need to change the DSN server manually?
how do i do that?

and how do i change the wireless adapter to obtain all addresses?

thanks

Best thing to do is to set the various addresses to be assigned automatically then you can forget it. Go to control panel, network and sharing centre, change adapter settings, right click on wireless connection. Single click on Internet Protocol Version 4 and click on properties. Select the options: "obtain an ip address automatically" and also "obtain dns server address automatically". Click on ok, chain back out and reboot.

Your dns server address is still set to an external address and I wouldn't expect it to be - check that you have selected the option "obtain dns server address automatically." If your are certain you have and it still does not show 192.168.1.1 as your dns server address in the ipconfig listing then you will have to set it manually - unchecking the automatic dns option and manually entering 192.168.1.1. You will always have to reboot after making these changes - did you do that?
 


#12
yes i did,
but if i manually configured
what is the alternate DNS server?

All looks ok. The alternate dns server may or not be valid but as long as your are connected to that router (or any router with an IP address of 192.168.1.1 it is not going to be ever used. Glad the laptop problem seems to be sorted.

Are you on a cable connection or ADSL? (Looks like it might be cable). What is the make and model of your router? You seem to have IPv6 enabled on your wireless connection - you are very unlikely to be using it and I would disable it.
