View Full Version : [SOLVED] Wireless / WiFi stopped working after Ubuntu 11.10 upgrade

I hope this helps someone out there, here's my story and how I fixed it.

After I upgrade from 11.04 to 11.10 my WiFi went out during installation and never came back on, even after the install completed. My netbook is a Sony VAIO VPCM111AX, I was familiar with the the ralink wireless issues so I had many rt2 and rt3 wireless drivers blacklisted. So I went back and unblacklisted these drivers.


sudo gedit /etc/modprobe.d/blacklist.conf

# These don't function with WiFi when netbook is unplugged
blacklist rt3390sta
blacklist rt2x00lib
blacklist rt2800pci
blacklist rt2x00usb
blacklist rt2x00pci

This didn't solve the problem. I went back to find my specific driver by this:


lspci | grep work

and I found that my driver was RT3090


01:00.0 Network controller: Ralink corp. RT3090 Wireless 802.11n 1T/1R PCIe

Upon some investigation I found that 11.10 doesn't support some wireless drivers.
Before proceeding I wanted to check a few more things such as


sudo lshw -C network

2: hci0: Bluetooth

If the "no"'s here are yes's for you run this:


rfkill unblock all

After all this I found an old version of the rt3090 driver here:

https://launchpad.net/~markus-tisoft/+archive/rt3090/+files/rt3090-dkms_2.3.1.3-0ubuntu0~ppa1_all.deb

I installed the driver and restarted the computer and all is well. I haven't had to reblacklist the other ralink drivers, everything seems to be working well.

I hope this helps someone because this problem drove me mad.

Just for reference: I did find that some computers needed to blacklist certain drivers depending on computer models:


blacklist bcm43xx
blacklist acer_wmi

There are a lot of other drivers that need to be blacklisted depending on the type of computer you have and others need to install older versions of the wireless driver (as I did) to allow this to work.

Thank you!

It worked as you said on my HP ProBook 4720s.

- I removed the blacklist rt2800pci (I had blacklisted this one when I upgraded to 11.04). This restored the ability to activate the wireless network using the wireless button. But I still couldn't connect to any Access Point.

- I installed the old driver using the link you provided.

- and I blacklisted bcm43xx and acer_wmi just in case.

Thanks again :)

Thanks OP. This definitely helped me. On my averatec N1200, it first gave me a warning that the "driver does not meet ubuntu standards" which I ignored. After reboot, it "forgot" my wpa-2 password. I had to retype it. Everything works now.

If anyone is looking for instructions.... all it needs it download and install deb file linked by OP using the software center. The install can take a while because it is DKMS, be patient.

I'm another satisfied customer; thanks!:)

on the downside...

I was rather worried at having to scorn two security warning in order to install the good old driver. This might encourage me to adopt such pig-headed behaviour at less appropriate times.

My confidence as a self-styled "Ubuntu evangelist" takes a knock when I hit this sort of problem.

Worked for me, I just had to add a line to the /etc/modules

rt3090sta

and after a reboot. Everything worked ok. :)

Hi, I have a Lenovo s205, and have been struggling really hard to get wireless working right.
I can get it to works in several different ways, but the network speed is very low.
Now I have downloaded the package "rt3090-dkms_2.4.0.4-0ubuntu0~ppa0_all.deb" from Markus Heberling, and installed it using software center.
It did not work, so I blacklisted "acer_wmi", and now it does. -But again at a terrible low speed. (below 80Kb/sec.)
How do I find out what drivers should be blacklisted, and what driver is actually being used?

I've been fighting this for 3 weeks straight, but now it finally works.
cirelosborn you are a true hero!

What it took was to install version 2.3.1.3 (I had installed 2.4.0.4)
Blacklist acer_wmi in /etc/modprobe.d/blacklist.conf
And add rt3090sta to /etc/modules

Intel Corporation PRO/Wireless 3945ABG is your wireless card. If blacklisting didn't work then find an older version of the intel driver "3945ABG" and install it. Hope this helps.

So here it is- the HP dv5020us laptop, complete with non functioning wireless router, it does not even look for a driver! Help!
At my prompt, I typed in this:

and I got this

What next?

Mine says soft blocked no..... But still the wifi signal keeps dropping every few minutes.... sometimes every few seconds...

can there be a driver error?

The dropping of the wifi signal every few minutes is a classic sign of switching between two or more wireless drivers. You need to blacklist all wifi drivers that your not using and it should stop dropping the signal.

This really works. Thanks a lot!
Actually, Ubuntu 11.10 has no problem with the rt2860sta driver. It connects and works decently. But what I was doing is recompile the 3.0.0.16 kernel because I needed to patch it after buying Genius EasyPen i405X graphic tablet, which had pressure problem in the current kernel. I got pen to working but I lost connectivity with my rt3090sta wireless card.
Tried a lot of stuff but this solves the issue.

I just reinstalled 11.10 (because I couldn't update 9.04!!)

I now have the same problem - no wireless.

I have consistently had problems with every single Ubuntu upgrade I have ever done. I'm not sure I even want to fix it this time...

Another thanks and sucess to the OP.

Advent Milano netbook wireless on Ubuntu 12.04 working. thanks.
ALso thanks to the poster who suggested adding
rt3090sta

to /etc/modules

Not 100% why that mod wouldnt already be set to load after installation but it got it working so thanks.

After an upgrade to Ubuntu 12.04 I have found no problems with the wifi in any manner.

I've tested this with an HP laptop, HP Desktop, Sony netbook, Acer netbook, and a strange Chinese netbook named S30 (I have no idea what it really is). Some of them had to be connected to an Ethernet cord for the clean install of 12.04. After install I looked for "additional drivers", using Additional Drivers app pre-installed, and installed the wireless drivers for the ones that needed it (not all needed it). That was it and everything worked beautifully. So far, on the wireless aspect end of things, Ubuntu 12.04 beats Ubuntu 11.10 hands down.

Thank you everybody for the support.
