I am using window 7 ultimate and my desktop contain two network ports. I plugged one port to internet network, and another port to my laptop for personal folder sharing. So , it will shows 1 port with network access, and another port with unidentified network. When i use my computer to surf website, sometime it will shows 'Unable to access network ' at browser. And i confirmed my internet network is working. How can i solve this problem?
