I have 12.04 LTS on a Toshiba Portege R835-P56X.

I try to connect to my home network over wifi. It connects, but I can't access the Internet. I tried resetting the router, but that didn't work. Please help!

Does it work on a different OS, or with a Live CD/DVD? – belacqua Jun 8 '13 at 23:51
Open a terminal by Ctrl+Alt+T, and type these separately: lspci -nn | grep 0280, ifconfig and route -n. Copy their outputs, edit your question, and paste the outputs in your question. – Alaa Ali Jun 9 '13 at 7:05

Check if the wifi card is blocked (Terminal)

rfkill list wlan (for wifi)


rfkill list all (for wifi and bluetooth)


rfkill unblock wlan (for wifi)


rfkill unblock all (for wifi and bluetooth)

Restart the network:

sudo service network-manager restart

These commands are if the wireless card is turned off/blocked and if he can't connect/search for wireless networks. The person that asked the question can already connect to a network, but can't access the internet. – Alaa Ali Jun 9 '13 at 7:07
