My computer (running WINDOWS XP) is on the network and can access the internet. It's IP address is set automatically (LAN -> Internet Protocol -> Properties -> Obtain an IP address Automatically).
It works fine with this. Now I wish to use separate line for internet access. So I simply disconnect the network cable and connect the new network cable.
This time my IP address is static (Predefined). So I configured the IP with the specified IP address and gateway. It works for five minute after configuration after which I am unable to access the internet.
After some time it starts working again but the problem is intermittent. When I connect the same cable with same IP address to any other computer system (running WINDOWS XP), it works fine all the time.
I think there is any problem with my computer system what could it be?
