Ubuntu 12.04 wireless connection problem

[aramaniac]

Hi there Ubuntu pro's!

 

I've encountered a really frustrating problem.

I've set up Ubuntu 12.04 on a new MSI laptop.

 

 

Thing is, everything works fine, except the wireless connection.

I can't seem to find any wireless network connections.

Normally you get different networks that you can connect to when you click the wireless icon in the system tray.

All I get is respectively:

 

Wired Network                                        (greyed out)

disconnected                                          (greyed out)

Wireless Networks                                 (greyed out)

Disconnected                                          (greyed out)

Connect to Hidden Wireless Network...

Create New Wireless Network...

VPN Connections              

V Enable Networking 

V Enable Wireless

Connection Information                           (greyed out)

Edit Connections...

 

So can't connect to anything and by what the terminal is showing me it seems that the network adapter is working fine?

Can someone please help me out?

 

So I'll give you guys a bit of information that I've managed to gather.

Please help this lost soul.

upgrade to 14.04 and make sure you don't have the wlan disabled with a hardware switch

[martward]

Absolutely no Linux pro, so excuse me if I ask stupid questions.

- Have you tried running all updates with an ethernet connection?

- Have you checked the extra drivers tab in the setting menu for any drivers which need to be activated for your wlan?

[flibberdipper]

Why are you on such an old release? That one is 3 YEARS old. Just leave it behind and get on 15.04.

[byalexandr]

sudo apt-get update

 

Make sure that is in check.

 

also:

 

ifconfig wlan0 down

ifconfig wlan0 up

 

or

 

sudo /etc/init.d/netwroking restart

 

If that doens't work make sure you don't have some sort of physical switch that turns the wireless connection on and off. Also list what

 

lspci

 

and

 

ifconfig -a 

 

says.

 

Edit: Like everyone else said, update to 14.04 LTS or later.

I tend to stick with the LTS versions, 15.04 will be deprecated in 9mo from whenever it released, so you're stuck upgrading again.

In the words of a normal person: Who the hell cares? It's not like pulling teeth when you have to upgrade.

Yep

[aramaniac]

Well, I've tried the 14.04.. Thing is, it doesn't support my network card

Ok, what model is the laptop?

if you're just doing basic computing tasks, yeah no problem

 

but there's been quite a few upgrade releases that have screwed me over many times. Like upgrading from 10.04 to 12.04, the upgraded version of apache, broke all my virtual hosts. I had to reconfigure them all again from the ground up. I believe that was the release that also switched from ALSA to pulseaudio, and I had no sound for a while till I figured out what had happened.

 

And lets not get started about when ubuntu switched to upstart. I had to convert all my startup scripts to be compatible with upstart, as my init.d scripts no longer worked properly.

 

When I upgraded from 12.04 to 14.04, my RAID driver no longer worked either because the kernel had been updated.

 

Shit breaks when you upgrade

Have you made sure there isn't a physical hardware switch disabling your wifi?

Did you install the drivers from the link I posted?

Yep 100% sure and I did, still nothing.

[Dabombinable]

Yep 100% sure and I did, still nothing.

If the wifi switch is on and the drivers didn't work, you might have a dead wireless card.

[MrBucket101]

Yep 100% sure and I did, still nothing.

you manually installed the drivers from source?

./configmakemake install
