Wireless issues with Ubuntu 11.04


Hey, after seeing how promising the new edition of Ubuntu was, I decided to install it along my current OS (Linux Mint 10).

Having installed Ubuntu without any problems I immediately installed both the wireless driver and my video driver in Additional Drivers; they are currently both 'The driver is activated and currently in use'.

Now with Mint, I could connect straight away to wireless but Ubuntu, no.

Having searched, I eventually changed the message under Wireless Networks to 'Device not ready' but after rebooting it's gone back to Wireless is disabled, even though it has been ticked

To get it to actually turn on. I’ve had to us 'sudo ifconfig eth1 up' and it even detects the wireless networks when I use 'sudo iwlist eth1 scan'.

Here are my ifconfig and iwconfig plus my wireless card :

Network card: Broadcom Corporation BCM43225 802.11b/g/n

Code:
ifconfig:

If anyone can help, I would be extremely grateful!

Don't worry, i've fixed it!!!

Here's the solution for others with this problem::

Thanks for responding, after much poking about I've found the solution.

As suspected the drivers were installed and working properly since they come with the 2.6.38 kernel however the "acer-wireless: soft blocked: yes" output of 'rfkill list all' was the clue.

Found these two posts

https://bugzilla.redhat.com/show_bug.cgi?id=655371
http://forums.opensuse.org/english/g...working-2.html

which pointed to acer-wmi module being loaded and causing the fault.

As soon as I did a 'sudo modprobe -r acer-wmi' my wireless sprang into life. At last!

I've since blacklisted the module and all seems well, the wifi LED is not lit but I can live with that.

Hope this helps any other Broadcom + Acer unfortunates out there.

Thank you!

I recently got a 7551g, and had the wireless working fine with the proprietary drivers from Ubuntu. However, the wireless was always disabled at boot. Blacklisting that module fixed it!

By the way, for those who don't feel like searching more (if you don't already know how), blacklist a module like so, at the terminal (replace "sudo vi" with "gksudo gedit" if you're not a masochist like me):

Code:

$ cd /etc/modprobe.d
$ sudo vi blacklist.conf

Add the new line "blacklist acer-wmi" (without quotes) to the end of the file.

Let me also note that my wi-fi LED works fine. If I turn it off with Fn+F3, the light goes out and wi-fi turns off, but network-manager still thinks it's enabled and continually attempts to reconnect. Fn+F3 again turns the light back on, and NM reconnects. No more than a minor annoyance to me, just wanted to point it out in case anyone else looks here for help.

Thanks again for posting the solution; been looking for weeks!

The problem is that the additional drivers are not compatible with Ubuntu 11.04.

Oalette.
Here is what you need to do. Use other Broadcom drivers. Download these drivers (from Windows or through wired network or a friend’s computer or from wherever you are reading this article ).

For 32 bit: http://ie.archive.ubuntu.com/ubuntu/...untu5_i386.deb

For 64 bit: http://ie.archive.ubuntu.com/ubuntu/...ntu5_amd64.deb

(Don’t know which Ubuntu you are using? Click here: Check you Ubuntu architecture)

Now remove the previous drivers in Ubuntu 11.04 by using: sudo apt-get remove bcmwl-kernel-source

Now install the appropriate driver (you have downloaded from the above links). Restart your computer. If restarting doesn’t work try shut down and then start it (strange…but works). Enjoy
