Hello,
I'm experiencing some network issue since yesterday, it can connect to LAN just fine, and i can surf too,but after few moments the issue starts up, i can't open up google or anything,
Some kind of DNS problem i'm guessing.
Now,i have tried going into safe mode with networking,my PC is in safe mode at the moment,the issue is not there in safe mode,i checked for a while in case if it shows the same issue even in safe mode,but good for me it hasn't,so far working fine. Can anyone tell me how can i resolve the issue in normal mode?

The first question is,

How are you connecting to the router or network.
Using a wired connection.
Or using a Wi-fi connection to access the router/ network.?

In any case the first things to look at are windows security center.
And the level of what the firewall is set to for a private, or public network.
If set to high, set the security to medium for both private, or a public network.

Make sure if thee is a fire wall rule for what ever you browser is you are using that in the firewall rules it is set to medium security for in and out going connections.

Your next thing to do is log into the router the whole network is connected to via your web browser.
Set the hardware fire wall in the router to Medium also if set to high.

Look in the router setup pages menu for.
Flood protection and disable the option.

If using a Wi-fi connection.
Go to the wi-fi broadcasting page of the router.
Depending on what Wi-fi adapter you have and it`s speed.
54g N-150/ 144Mbps or N-300.

Lower the broadcast frequency to a value below what the adapter you have states in your routers wi-fi broadcasting of the network, and for internet access.

See if the problem is resolved with Dns lookup of web page addresses in you browser after the changes are applied or stored in the router settings.

Also when using the browser of your choice, right mouse click on the desktop icon for it, and select run as Admin.

If the browser then opens and works.
Right click on the icon again to launch the browser.
Click on properties.
And tick the check box that says run as admin.
Then you can left click on the browser and it will automatically run it in Admin mode.

Checking both of the points mentioned should resolve the problem.

Hello, i have wired connection/ connected with ethernet cable

EDIT: i was just roaming around in network settings and went to "Network Connection Details" where i saw my physical address is
"88-88-88-88-87-88" no idea if it is normal or might be causing the issue

If you click on start of windows.
Then in the search box type : Cmd.

Then press enter.

It will open a dos command prompt window.

At the prompt type : ipconfig /all.

It will show you all the settings the router gave the network adapter of you computer.

The Ip address.
The subnet address.

The gateway address/ known as the router.

And two Dns server addresses for web page look up.

Dhcp should be set to a status of enabled when looking at the displayed information.
Any value for the Dns servers that is 0.0.0.0.0 means no dns server addresses are setup in the router and it must be configured by logging into the router.

The 88-88 ect value is probably the hardware Mac address of the ethernet adapter, Lan adapter of your computer.

Thanks, as mentioned earlier i was in safe mode and it was working fine,now i'm running on normal mode and so far it is normal,but i doubt it's gonna be like this the whole day, but let's just hope.

And, none of my DNS servers are 0.0.0.0 , Dhcp is also enabled.
