  1. hi there, my internet was running fine until yesterday, when I tried to connect to the internet, the message "windows can't communicate with the device or resource (primary dns server)" came up.. I followed all 4 methods on this website: http://answers.microsoft.com/en-us/w...3-b5d1ec46fae5 but none of them worked for me, I then returned my laptop to factory settings in the hope it will work, but that didnt not work, I then realised it works through the ethernet cable but not wireless..
    I ran ipconfig/all with my ethernet cable in and this is the result.. SOMEONE PLEASE HELP ME THANKYOU

    There may be an issue on the ISP side or router side since restoring to defaults didnt help. Or it could be an issue with the network adapter. Or it could be an issue with the firewall.

    Try downloading running these tools (download via ethernet, run on wireless): Network Fix-It Tool (right click on the internet bars on the task bar in the bottom right hand side of the screen, and click "troubleshoot network...") and Firewall Fix-It Tool.

    Did you install anything on your PC before this happened? Did Windows install any updates?

    Try disabling your AntiVirus. That may be the issue. I doubt it though.

    Tell me if any of these solutions help.

    • Can you ping 194.168.4.100 ?
    • You said this is the result with you plugged in via cable, but the result shows that cable is unplugged and you are connected via wifi.

    Sorry to make things clear I have taken the ethernet cable which is usually attached to the wifi box to my laptop, which is why it says im connected however when I try to connect to the wifi without anything it will not work, it still says windows can't communicate with dns server. and I will attach ping 194.168.4.100 now, but I have the ethernet cable in :)

    Use one or the other but don't try both Ethernet + WiFi at the same time. The DHCP for the wifi gets lost due to the active ethernet connection.

    BTW: If the Ethernet wired connection gets configured correctly (as you have shown), then there's absolutely nothing wrong with the TCP settings and you don't need ANY fixit :)

    You *may* need a better WiFi driver however.
