  • try dropping in sudo dhclient wlan0 and follow it with ping -c 3 www.google.com.. If that works, you need to go into network settings (click on the cog in the top right>system settings>Network>wireless>click on the orange arrow associated to your network>settings>ipv4/ipv6 settings and turn on dhcp.

Maybe it is a proxy related problem.
When I shutdown OS with proxy software on, I can't access the Internet the next time when boot into this OS.
In this case, open proxy software again may solve the problem.
