The networking function of my laptop doesn't work and I cannot get access the web.

[Information on using ping]
My laptop is DHCP enabled, which could get an IP from DHCP server. But now it doesn't work.
It cannot get an IP similar to before. It only has an autoconfigured IP address, which doesn't have a default gateway.
ping works fine for 127.0.0.1 and computer IP.
If I disable DHCP and use previous IP, ping doesn't work for the default gateway.
