Computer with no Internet access, a packet is O

Users questions: Recently the computer does not always connect the Internet using a wireless router TP. Packet is always 0, can not login the router interface. Students access to the Internet using the same router. Feel the problem lies in the IP address, IP address manually assigned, before I remember that DNS is automatically assigned to remove the router and Cable problems. Sometimes restarting the next like, and do not know whether the problem is motherboard integrated NIC. Ask the next master ~
Experts answer:DNS manually assign it? To remember their own DNS server address.
