Ok I have tried doing this on my own and am asking for help.
My connection manager shows wired connections and shows wireless as being disabled.
here is some terminal info any help getting wireless going?


Here is a bunch of things I have tried and the results.

The BCM4303 is supported with the bcm43xx module. Have you got it loaded? In a console as root, run the command 'lsmod' and look for the module. If it is not loaded, you will need to use modprobe to load it. Then you can configure the card.

If it is loaded, there is some other issue. Post the results of 'ifconfig' and 'iwcinfig'. All commnads without the quotes.

ok here is lsmod

Thanks for helping me work on this. A few weeks ago I had issue with a USB wireless and got that working but I am not sure by what means I did so. I then came across a free wifi card from a friends dead pc and installed that. now nothing wireless is working on this pc.

The module bcm43xx is not loaded. The card will not work until it is installed, and loaded.

You can try as root to 'modprobe bcm43xx' and see what happens. If it reports 'module not found' ( probably will ) you will have to look in Synaptic for the package that contains it. Once installed, you should be able to modprobe it then.

When you use modprobe, no news is good news. If it loads, then run lsmod again, anc confirm it is there. Then you can start configuring the card.

I really thank you for your help and I did get the Module not found. Is there a place i can get a step by step for doing this and info on how to configure the card.?
I am going to keep playing. Last time I got this working I just wish i knew what i did. but none the less not going back to Windows anytime soon!

I would suggest looking in the Ubuntu wiki, here -->https://wiki.ubuntu.com/

I have not looked for your card in particular, they do have some excellent documentation. Look for a wifi HowTo.

The b43 legacy module is what the system selected for your device. The bcm43xx driver is for even older kernels.
You need to cut out the firmware from a Windows driver. Look for a package with a name such as b43-fwcutter to do this. I haven't seen this device with 'legacy' in its name before, but I think that for more recent broadcom devices a staging driver is used.
Posting your kernel version and the manufactures code for your device (from `lspci -n') may help.

I didn't notice that your device was just a wireless b device. so it is old hence the legacy.
This page lists your device and has instructions on installing the firmware. http://wireless.kernel.org/en/users/Drivers/b43
Bcm43legacy is the correct kernel module. You need to install bcm-fwcutter (if it isn't), download the driver with the firmware and install it.

After this is done, modprobe the b43legacy module and then run "sudo /usr/sbin/iwlist scan". That will tell you if the wireless device is working. If it is, the next step is configuring the device and wep or wpa.

Good Luck!

I also have a "you are no supposed to be here" redirection page for any directory that I don't want people have FTP-like HTTP access... once, I accidentally discovered a friend's resume/CV in one of his sub-directories. I think any directory without index.html or index.php automatically have get an FTP-like html interface (if you know what I'm talking about)... like /images/ directories, which I believe most websites will have. A bit of a side-question... is there a technically correct or easier way of preventing such "unauthorized" access to these directories? I can't quite figure out a way with permissions, since for most of those directories, you'll need to set it readable by public for them to access the contents (e.g. images, javascript, etc).
