Hello,

I am new to Linux and I know close to nothing about working with it, so I have no clue where the problem comes from.

Here it is: I had the 32-bit version of Lucid (on a Dell laptop) and just installed the 64-bit one.
Before the installation, using the live CD, I used cable connection to the internet and it worked, and I let the laptop connected during installation.
When the process was completed, an icon appeared and suggested I download and install Broadcom STA wireless driver, which I did.
(The same happened when installing the 32-bit version of Lucid and I had no problems with that one.)
Cable still works. I cannot log on to my wireless network though.
I see it in the drop down menu, but when I try to connect it just doesn't happen, the window for the password comes up again and again.
(I am certain the password is correct, I have it written and keep it with the router's documentation.)

I tried searching the forum and I found this suggestion:

I have no idea what the deal is with these files and whether or not it can be relevant to my problem, but I tried it anyway. Nothing changed after restart.

Ok, this is going to be very very long...

By the way, the reason I post this here is because I got confused... I could not decide whether this is a 'wireless' problem or a '64 bit' problem. And I am an absolute beginner, so... If this is the wrong place, I apologise.

So... any suggestions? I really would like to try 64-bit linux, but I am lost with no internet. Hm, now that I think about it, I could just buy another cable and connect my laptop to my router, but it's not really a solution is it... the whole point of the laptop being mobility.

Also, the files I mentioned I removed from the /lib/firmware directory, should I move them back there? (I kept copies elsewhere.)

Yes, I think you should; most of these are "drivers". You see, Linux doesn't use separate drivers just for two different pieces of hardware -- it works out which driver to use based on it's chip model (can't remember if this is micro-processor or something else right now).

In addition, I haven't taken into account any of the logs you posted from the terminal, this is just some plain advice... connect via Ethernet and visit your manufacturer's website to see if they have a driver for your wireless card that is compatible with Linux. Or look for a community-made one (if possible). I'm kind of a beginner to hardware stuff as well, but if it is a software bug..it's most likely to do with your hardware not having its driver installed by default in Ubuntu. Also, go to [System > Administration > Additional Drivers] to see if the system can automatically locate drivers for you (be connected via Ethernet when you do this!)

Thank you, I will move them back when I get on my laptop again (kind of no use at the moment... I am looking for info online and going back and forth between the two desks got old really fast).

The Broadcom driver was suggested, and I installed it. It worked ok with 32-bit Lucid, so... Heh, I guess it's never late to run out of luck.

Thank you for your reply.

Well, something must have worked.

I came back yesterday and turned on the laptop, and all of a sudden the wireless network was found and connected to with no action required from me. Weird.

Why this did not happen after a previous restart is beyond me. :?

Does your system automatically update? There was a kernel revision recently; that could've fixed the issue.

Anyhow, be sure to mark this thread as "Solved" so that others can come here for advice and to prevent inane posts! You can do this at the top of this page by selecting "Solved" from one of the drop-downs (I can't remember the name but it's pretty obvious...) ;)

I did it already :D Although it isn't actually clear what solved the problem, but I think I know somebody who can help me figure it out (it'd be easier talking face to face and with my laptop present), and when I do I will edit this, so it be known.

(And no, my system doesn't update automatically, I prefer to know when things are about to change and to choose these changes; and during the last use of my laptop previous to the start up followed by connecting to the wireless network I wasn't connected anyway, so an update couldn't have happened even if desired.)
