WiFi connected to router, but no internet connection
- by Quetzacotl
I just got a new notebook, a ThinkPad Edge E530, and installed Ubuntu on it. I'm pretty new to Ubuntu. On the same laptop, running Windows 7, the Wi-Fi connection works fine. Ethernet connection works both on Win7 and on Ubuntu. Only Wi-Fi on Ubuntu does not work; it connects to the Wi-Fi access point but I don't have Internet access.
My wireless card is Intel Centrino Wireless-N 2230.
What can fix the problem?
