问题解答：

u are using fix or dynamic IP? If u are using dynamic IP, actually should be ok；but if u are using fix ip, make sure that IP must be different for each computer. Sometimes that maybe the problem from NIC or RJ45 cable or port on the hub/switch. Try to use the command "ping ip" example
ping 192.168.1.1 (if you get reply from the default gateway,so everything must be ok!)

呵呵，可能是代理或者路由器限制的问题，也有可能是分配的ip地址不够用！
