I am a new user to Linux and have loaded Ubuntu 12.4 on my HP Pavilion Pv4 and having a problem with not being able to use my wireless
connection. The hard wire connection works fine. Someone suggested to change the file B43-FCcutter and bcmwl-kernel-source but not sure how todo that, or is there a better solution? When I load Window Vista the wireless works fine. Any help would be appreciated.

Thanks
Don

Hello and welcome to LinuxQuestions,

I just reported your other thread on the same subject for closure, stick to this one please. Posting a thread in multiple forums only confuses you and us on to where the conversation is taking place.

Normally Ubuntu does a pretty decent job on detecting and activating hardware so I assume your problem will not be to hard to fix. Can you open a terminal and post the output of the following commands please:
Looking forward to your participation in the forums. Have fun with Linux.

Kind regards,

Eric

This is the result from your codes

This is the command EricTRA meant, it's a lower case "L".

If you go to "My Computer" in Vista and right click the go for propertied and then "Hardware" and "Device Manager" Expand the Network line and post us the contents. This should help to identify your WiFi card/chip set which would be helpfull.
(That's what I'd do with XL, I'm not sure how similar the path in Vista is.)

Play Bonny!

Wireless adapter from above, forget my Vista comment.
you may need an add on Kernel module loaded to activate it.
