I am new to GNU Linux. I have been having trouble getting wireless working on my installed system of Lubuntu 11.10. It sees my WPA network but cannot connect even when I remove the password.

Looking around for a different distro that might replace it, I was amazed to find that Puppy was able to connect to my wireless network without trouble, running off a USB stick. So this makes me think that my Lubuntu wireless problem might be fixable so I don't have to have the major hassle of backing up all my documents etc before installing a different distro to the laptop. Can anyone suggest some steps that might help me to fix wireless on Lubuntu, perhaps using the fact it works with Puppy? Thanks.

Rob

EDIT: (Thank you both for the advice and link on making the question more useful. Hope this is better...)

(PS. WEP doesn't work either; rebooting doesn't help)

Here is the output for Lubuntu (wireless network on; wired ethernet connection to laptop unplugged):

The output from

cat /var/log/dmesg
cat /var/log/Xorg.0
ls -lrt /var/log

is here if required! (pardon my ignorance)

Further (more than a month later):

Well, finally I tried the suggestions on that page suggested by fossfreedom, and pages linked therein (did things one at a time with reboots where suggested):

did the suggested uninstalls (bcmwl-kernel-source package),
did the installs (firmware-b43-installer and b43-fwcutter packages),
commented out the blacklist (in /etc/modprobe.d/blacklist.conf)

etc, etc, and variations suggested.

Wireless still doesn't work.

Out of interest, here's what I get with the following. Is the "access denied" significant/suggestive? Does anyone kind, lucid and patient, have any other ideas?

Also,

modprobe -r wl
FATAL: Module wl not found.

Another point: in Additional Drivers, the proprietary driver is still shown but is not active. Couldn't see how to remove it (only inactivate it). Neither worked (active or inactive).

My PC-ID of [14e4:4311] is supported according to this page: http://wireless.kernel.org/en/users/Drivers/b43

I don't grok at all what's going on. Not even the basics. Did at one point but am so befuddled now that I need a holiday. It's clear this distro was a bad choice for my level of non-expertise (will inform the friend who suggested it but uses something else; feel like a guinea pig).

I understand that your driver seems to be properly connected, but it would be helpful to know what your wireless adapter is. Please copy your wireless adapter from lspci (or lsusb if it's a USB wireless adapter). Also your output from ifconfig. I guess rebooting doesn't solve the issue? What if you disable WPA, is it able to connect? –  titaniumtux Apr 14 '12 at 4:55

Still not had the chance to try these out. Will do this weekend. Thanks, fossfreedom... –  user54871 Apr 20 '12 at 4:59
    
Tried them out today. Still stuck! –  user54871 May 23 '12 at 18:49
