Question

how can my laptop not conected wifi network dns configuration problem solve

Answer 1

Its very simple steps to do it
First check your WiFi wires and others wires properly
May be your router of your WiFi is not able to connect with the particular satellite
In that case wait for some hours because there are lot of radioactive signals traveling here and there
Either do one thing change your Wi-Fi password and try again
A dialog box appears in front of you to solve troubleshooting check that's that problem and then call your nearest mechanic or you can ask me

Answer 2

just go to control panel and then networking and internet there wold be option Troubleshoot option click on that and clear or solve all networking problem
then again try to connect to WiFi if it shows the option of required network then click on it
next click on connect
and then u have to fill the password in the column and connect

I hope this helps I know this and. bcoz I also faced the same problem while I was connecting my laptop to WiFi...
