I've first heard of something called ubuntu just two weeks ago and it was 10.10 then I've upgraded it and now I'm using 12.04.1 LTS but the wireless connection was working well on 10.10 but in 11.04 and 11.10 and 12.04 it's not working except when wired so I don't know what to do now ?

It probably needs a driver. Please do the following:


open a terminal window
type lspci > ~/abs-wireless.txt <press enter>
type lsusb >> ~/abs-wireless.txt <press enter>
type iwconfig >> ~/abs-wireless.txt <press enter>
type ifconfig >> ~/abs-wireless.txt <press enter>

Please note the first line has single ">", all the rest have 2. The above is creating a file in you home folder with some information we need.


Now post a reply back here, click the paper clip and attach the abs-wireless.txt file from your home folder.

Same problem here so I hope you don't mind me piggy-backing your question?

Mine says this:

martin@martin:~$ lspci > ~/abs-wireless.txt
martin@martin:~$ lsusb >> ~/abs-wireless.txt
martin@martin:~$ iwconfig >> ~/abs-wireless.txt
lo no wireless extensions.

eth0 no wireless extensions.

Yes - should there be more (I'm a beginner here so I'm finding my feet here)

WYSIWYG with that output I'm afraid....

Thanks.

Are you saying here that there's a bug-fix been released? I ask because I installed Ubuntu 12.04.01 LTS about 10 days ago.

Also, if it is a bug-fix, I have no clue how to install it (and I'm v new to Ubuntu!) Could you give me a steer?

Thanks

Yes, it fixed in the version Raring Ringtail, which is the development version due to release in april under the name 13.04.

You can install it now, but be warned that it is a work in progress and likely to be unstable. You might need to return to a stable version.

Great stuff - that worked. At least it's worked for two reboots so far!

You're welcome - here's hoping it keeps working! ;)

Now that your problem is apparently solved, you can answer this for the next person who posts on the same thing - isn't that great? Goes to show how to get started answering threads - like the rest of us, learn one thing at a time and pass it along when you can. There are some real experts in Ubuntu out here - I'm just a lowly guy who tries.

As morgaes mentioned above, it would greatly help to have any messages, screen prints (including what shows in network manager), and a part of your log file to see what messages the system might have spit out when initializing.

I am not sure if I can use this same thread also myself but I try. My problem seems to be similar with others. Can I use the same pieces of advise as for the others given here?

Also, has xubuntu proposed any drivers for you to install regarding the wireless, and if so have you done this? Any other action you have taken so far regarding drivers?

About the drivers. There was a suggestion of restricted drivers but were not downloadable. The D/L discontinued in about halfway.

I guess I want to make clear that I am learning this stuff and I am complete newb. it's okay.. I have a accepted that I will seem like a moron so it's okay to mock... So do I need to make that text file or is that beside the point now?

I know it's a broadcom driver that is the problem. and my computer that I am using ( not right now) is a lenovo 3000- n100 (seemed like a good idea at the time) and of like the rest 11 worked perfectly fine.

As the wireless connection is working on Windows, I was thinking that if I try re-installation of Xubuntu and keep the wireless connection on during the installation.
It might help - or not. The present system was done with a wired connection only.
On Xubuntu I cannot see any wireless connections at all now.

Has anybody tried that with any success? Although I think the problem is with
some drivers and configuration.

The present system was done with a wired connection only.

This is by far the best approach.

Install and apply all updates using wired connection. Verify through a couple of reboots. Only when that works you can (and should) pull the plug, as the wirefree connection might switch itself off when the wired one is present.

I too am watching this with interest and my level of knowledge/expertise in this is way below that of everyone else.

When time permits I currently browse the forum to see what I can find out about what the results in the terminal mean - uphill struggle, bearing in mind the first sentence above.
