No wireless after updating packages in 12.04

[Rosz777]

I use Ubuntu 12.04. Yesterday system asked me about installing updates. I clicked install update. After that, I don't have option to connect any connection cause i don't have an option wireless network, only network or mobile network. This is the output of lspci:

Please do help, thanks in advance

Please try this:

sudo modprobe rt2800pci

Does your wireless spring to life? If so, it's a simple fix. If not, let's see if there are any clues here:

rfkill list all
dmesg | grep rt2

[Rosz777]

wow, it works!

martyna@Martyna:~$ sudo modprobe rt2800pci
[sudo] password for martyna: 
martyna@Martyna:~$ rfkill list all

    Hard blocked: no

Is there anything else I should do?
thank u a lot!

[chili555]

Let's get rt2800pci to load automagically every time:

sudo su
echo rt2800pci >> /etc/modules
exit

rt2800pci_mcu_status: Error - MCU request failed, no response from hardware

I'm not sure I like that but let's see how it goes. Post back if your wireless isn't working properly.

Please let us see the usual suspects:

lspci -nn | grep 0280
rfkill list all
lsb_release -d

Thanks.

i must add, that this situations i'snt the same with the previous problem, cause now i have option to switch on and off my wireless card but i can't connect with any network because ubuntu constantly ask me about password. 2 months ago i had the same situation and i added

blacklist rt2800pci
blacklist rt2800usb
blacklist rt2x00lib
blacklist rt2x00pci
blacklist rt2x00usb

to etc/modprobe.d/blacklist-rt2x00.conf
but i checked this and i have this folder now but wireless still doesn't work

thanks for ur help

Hi all, I've got the same problem. I updated my lenovo T420S to 12.04 LTS and I'm not given any wireless connection option.

I've tried the command lines above but I don't make progress. Anyone can help?

Thanks in advance!

Just to add to the above, this is how far I get in the Terminal:

frederic@erasmus:~$ sudo modprobe rt2800pci
[sudo] password for martyna:
frederic@erasmus:~$ rfkill list all
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
frederic@erasmus:~$ dmesg | grep rt2
