Hello this is my first experience with linux and I just installed the newest version of Ubuntu.

My laptop is about a year old HP DV4 with broadcom wireless.

When I go to HP's site to get drivers they are all for Windows.

Right now I have to plug in to the cat5 to get internet. Where/how can I get my wireless working?

Also while I have a thread created how do I actually install Nvidia drivers?

I downloaded the correct driver from Nvidia... and like i said in the previous post this is my first experience with Linux.

Your Broadcom chip is now native if you use a 3.6.32 or .33 kernel. You will need to look into a program called b43-fwcutter to allow you to obtain and prepare the 4312 firmware for use on your system

If, for some reason you cannot run the .32 or better kernel, you will need a kernel module called broadcom-wl that was supported by broadcom themselves. I don't know about Ubuntu, but other distros call the package things like broadcom-sta. It also requires b43-fwcutter

As a last resort, I did manage to get it working with an XP driver and ndiswrapper, although scanning and relative signal strength functionality was badly crippled (I also heard that it was nearly impossible to associate with a hidden ssid)

My DV4 -1227us uses Intel graphics -- I can't offer any Nvidia advice.
