    DNS server is not responding

    I'm back again. People will start thinking I only come around when I got trouble. Wait a minute! That's what everybody does!

    I am using Chrome 34.0.1847......

    I am unable to connect to any website at all. When I use the Windows 7 troubleshooting, it tells me: 'DNS server is not responding.' I have had this problem to varying degrees for a while. Now it is total.

    My desktop computer is wirelessly connected to a DSL router using Current link.

    I even tried Restore, but still, nothing. Help! And thank you.

    Your PC should have the network set to use DHCP and the router then provides all the information required for network access. Check that this is the case by running the following:
    Start > Run > cmd > ipconfig /all
    You should see something like this:
    Code:
    Windows IP Configuration
    Ethernet adapter Local Area Connection:
    
       Connection-specific DNS Suffix  . : home
       Description . . . . . . . . . . . : NVIDIA nForce Networking Controller

       Default Gateway . . . . . . . . . : 192.168.1.254
       DHCP Server . . . . . . . . . . . : 192.168.1.254
       DHCPv6 IAID . . . . . . . . . . . : 234889168
       DHCPv6 Client DUID. . . . . . . . : 00-01-00-01-18-...
    
       DNS Servers . . . . . . . . . . . : 192.168.1.254
       NetBIOS over Tcpip. . . . . . . . : Enabled
    The DHCP server and DNS should be the same unless you have a strange set up. Pinging the DNS should work - Start > Run > cmd > ping 192.168.1.254.
    Post your config here if you are not sure.

    cheers, Paul

    What machine/device is at 192.168.0.16? Do you have a second router?
    Log into your router and see what the DHCP server settings are. DNS should be the address of the router unless you have changed it to an external DNS.

    cheers, Paul

    We have a router and an extender to get wireless signal through all these thick old walls.

    The priority is a strong signal to my wife's home office. My office is at the other end of the house.

    Suggestion?

    Not until I know what the device at 192.168.0.16 is - make and model. Put 192.168.1.16 in your browser address bar and see what comes up.
    A config from "ipconfig /all" from a working PC would make certain we get it right.

    cheers, Paul

    1) Try pinging website directly to see if you can see the internet without resolving.
    ie

    ping 8.8.8.8

    2) Check internet options / proxy settings - it should not be ticked unless u r using a proxy server,
    Some malware alter this to point at nefarious servers.

    3) Setup your dns manually to 8.8.8.8 and 8.8.4.4 this will bypass the router and can tell you if the router/firmware is hosed.

    Few things I try first.

    Last resort in case your tcp/ip stack is corrupt is to use the net ip reset command.

    For what it's worth guys, this just happened to me. My DSL connection was gone and everything at my end checked out. I ran a DSL modem/router diagnostic and got that "DNS servers not available" message. I called my ISP, went through checking everything out, and they sent to the second level of customer support. They called me back the next day and said they were having a problem in my area and they should have it fixed in 1 to 2 business days. The next day it was fixed! So this may be the thing to do if you haven't.
