I have installed 64-bit Ubuntu 12.10. I have Intel cupertino-N 6150 wireless adapter.

At university, where I have no password, I am able to connect to the wireless network seamlessly, however at home, where I have a password, I cannot connect.

I am sure that the password I type is correct ( I rechecked the password on the other devices which connect)

I tried different security settings, still without any luck.


After restarting the router my computer was able to connect to the network. Do not repeat my mistakes -)

Let's try this:

click on wifi icon, go to "Edit connections", go to "wireless" tab. Delete all the entries, click on "close". click wifi icon again, select your network and try connecting again.

ok then try this: press Ctrl-Alt-t; A terminal will pop up; type

rfkill unblock all

press enter

now restart network manager; type:

sudo service network-manager restart

press enter. It'll ask for your password, as you type it in there will be no feedback. That's normal. Report back.

I tried, it didn't help. – Gnattuha Feb 18 '13 at 22:59
It restarted the manager, but i am still not able to connect to the network. P.S. I appreciate your patience; these questions are outside of my expertise. – Gnattuha Feb 19 '13 at 1:51
ok. before I ask you to run some diagnostic tools, let me ask the obvious: have you tried turning your router off and on again? :) – phipsalabim Feb 19 '13 at 2:04
Wow, after I restarted It connected immediately. Thank you Sir. I apologize for taking so much time on such a fulish problem. – Gnattuha Feb 19 '13 at 2:13
No problem, happens to the best of us. I'm glad it's working. I'm sure that you'll remember the on/off "solution" for future problems. It's strange how often it works. – phipsalabim Feb 19 '13 at 2:22
