1st try: i was thinking theres a virus so i fullscan my pc and install winsock... still the effect is the same the status is connected but i cant connect to internet when i open browser either firefox or IE.

2nd try: when im sure the its clean and no virus, i tried to reinstall the networkadpter but still the same "page cannot be displayed" but connected on the network.

3rd try: i formatted my pc installed all drivers and after same effect again cannot connect in the internet "page cannot be displayed"

4th and final try: i thought that theres something wrong in the network cable.. so i buy new rj45 with the netowork cable and still the same "page cannot be displayed".

it sounds like you did not enter the DNS server info under the NIC's properties.

check under your Local Area Network (LAN) Settings in the Internet Options.

sometimes malware will check it for you and redirect your info.

it should not be checked.

did anybody set a limiting IP range in the router to allow access to port 80?

Do all your computers use PUBLIC or LOCAL IPs? How about testing the IP?

Look up the IP info of one of the other computers, turn it off, and assign it to your PC. See if you can access the internet using an IP you know that is able to browse the internet.

Have you talked to your ISP?

have no idea i think local ip's because all the internet protocol (TCP/IP) settings are all the same they are all automatically detected.... IP and DSN... i really cant find the problem here...

See if you can access the internet using an IP you know that is able to browse the internet.>>> yes i know that if you can ping a website in the cmd then you can browse it to the browser right? but in my case i cant browse it in my browser... if the problem is in the ISP why i am only one affected in our LAN? i tried to connect my lan cable to other socket in the switch but still the same problem occur....

There are technologies you have to consider when you want your home net to be connected to the internet. Some you can set the IP address automatically some don't. The switch hub is a way of connecting pc including the net. Check your ISP if you are allowed to do this with a switch hub or with a router, they will give you details on that. One way of checking things is to go to the Control Panel (In Windows),click on Network and Internet, click on Network and Sharing Center, here you will have an idea where you are connected.
