Cannot connect to wifi on 12.04 at all

**ObeseRocket** · April 29th, 2013

Hey there,

Just installed 12.04 on my laptop and I keep getting the "Wireless Network-Disconnected" message pop up, and have, in vain, been unable to find some sort of solution to get my laptop to connect to wifi.

Help?

thanks

Welcome to the forums ObeseRocket!

Please open a terminal (Ctrl + Alt + T), enter the following command (you may copy-paste to avoid typo) and post back its output here -

Code:

lspci -nnk | grep -iA2 net

If it is a USB adapter, then -

Code:

lsusb

PS:
We all were noobs once, and still are in many respects

Oh my! Please check :

Code:

dmesg | grep wl

If it shows error messages like -

ERROR @wl_cfg80211_get_station : Could not get....

.. then please check out this thread : http://ubuntuforums.org/showthread.php?t=2140263

A possible solution is in post #6 (not confirmed yet, awaiting feedback from the OP)

However, if your dmesg output is free of such error messages, please follow the "Wireless Script" link in my signature and post back what the linked post asks to.

..and is such a nice and welcome feedback!

Hope it proves to be stable and let's also hope it gets fixed soon in the newer versions of the driver so that users don't have to go for workarounds.
