wireless won't authenticate [12.04][ralink3090]

**louis_mallow** · June 8th, 2012

I moved from 10.04 to 12.04 by clean install. Previously I've had to use additional drivers, but 12.04 seems to recognise my wireless card no problem. The card can see my home network. Wired networking is okay.

No matter how I configure the wifi network, 12.04 will not connect; keeps looping back to 'Authentication required by wireless network'. All Windows and Android and iOS devices still connect fine.

Tried:
Setting wifi to WEP, also open, usually WPA2 AES
Every concievable setting in the network manager

I put off upgrading until a LTS came out to avoid this sort of thing. Makes me sad.Please can the community help me save Ubuntu's reputation in our house?

Please show:

Code:

lspci -nnk | grep -iA2 net
lsmod
iwconfig
rfkill list
dmesg | grep rt2

What kind of computer is that?

Plus this one:

Code:

grep rt2 /etc/modprobe.d/*

Hi, it's an ASUS Netbook, with a (fairly common) Ralink 3090 card.

Here's the output from thos commands:

The card is "on", try to uninstall the package "resolvconf"

Code:

sudo apt-get remove --purge resolvconf
sudo /etc/init.d/networking restart

Maybe it helps to deactivate the PM:

Code:

sudo iwconfig wlan0 power off

Thanks - tried all that, still no success. However, I've decided that since Unity has made this whole thing four times more difficult, as well as the wireless issue, the new Ubuntu just isn't for me.

Many thanks for your help, but I'm now going to distro-surf and find a new OS for the netbook.
