Connected to WiFi but not internet – Ubuntu 14.04

The wireless driver installed properly, able to connect to WiFi but not able to surf internet.

My case:

Dell INSPIRON N4050WPA/WPA2

Solutions:

1) Connect to WiFi

2) Edit Connections > IPv6 Settings > Method: Ignore > Save

3) Disconnect and reconnect to WiFi

That’s it 🙂

p/s: IPv4 Method: Automatic (DHCP) addresses only, adding “8.8.8.8, 8.8.8.4” into IPv4 “Additional DNS servers” might also helping.
