Ubuntu: No wifi connection for Centrino Wireless-N + WiMAX 6150


I am a new Ubuntu user; I recently switched over from Windows (pats self on back). However, I can't seem to figure out how to get my wireless connection to work. The only way for my connection to work at the moment is by Ethernet cable. Basically, I can detect all of the connection sites in my area, but once I select the one I want and I type in the password, it thinks for a moment possibly trying to get me connected then it brings me back to the password window. I've ensured I'm using the correct password, and I don't know what to do at this point. Any direction you could offer would be greatly appreciated.

My network controller is: Intel Corporation Centrino Wireless-N + WiMAX 6150

Thank you for your time!


How odd. It sees the wireless device, and even its connections, but won't connect. I've heard that a lot lately, but so far only about version 14.04 and 14.10. Maybe I should just be glad I'm still using 12.04?

I suppose it could be that the default driver your wifi device is using isn't quite right.

Generally speaking, if you are connected to the internet using a wired connection and perform and update, drivers for such hardware will automatically be installed. Not always but mostly. It is always my first thing I try.

Have you tried clicking on additional drivers under system settings?


That is one of the newer Intel Wifi Cards: it currently does not have native support--as far as I can tell. What you need is the right firmware. I have found the firmware for Centrino Wireless-N + WiMAX 6150 as well as brief instructions on the installation of firmware.

Download the corresponding firmware tarball. (iwlwifi-6050-ucode- Unpack the tarball, change into it's uncompressed directory, and move the iwlwifi-6050-4.ucode file to the firmware directory, /lib/firmware.

user@bash-X900V:pwd$ tar -xvzf iwlwifi-6050-ucode*  iwlwifi-6050-ucode-  iwlwifi-6050-ucode-  iwlwifi-6050-ucode-  iwlwifi-6050-ucode-    user@bash-X900V:pwd$ cd iwlwifi-6050-ucode-  user@bash-X900V:pwd/iwlwifi-6050-ucode-$ sudo mv iwlwifi-6050-4.ucode /lib/firmware/  user@bash-X900V:pwd/iwlwifi-6050-ucode-$ sudo reboot  

Reboot and pray.


Even I did face the same issue. The Ubuntu default network manager has some issues. I switched to new Network Manager WICD which solved my problem.

sudo apt-get install wicd
