To setup wifi - Intel Centrino Advanced-N-6230

[maxim13]

I am beginner in Ubuntu. I would like to setup wifi. My laptop is:
Dell - XPS15, wifi - Intel Centrino Advanced-N-6230 .
I tried ndiswrapper - doesn’t work. I downloaded driver iwlwifi-6000g2b-ucode-17.16ac8.5.2 and copied one to /lib/firmware … but without any results. For Windows - all ok!
Thanks!!!

Do I need exactly "iwlwifi-6000g2b-4.ucode"

Yes, indeed. Is it in the package you downloaded? Can you move it over to /lib/firmware?

Unfortunately I have no this file.
Where can I find it?

Here
http://git.kernel.org/?p=linux/kerne...are.git;a=tree
only 5's version.

Thanks!!!

I'm googling and suggest you do the same. I am off to dinner with Mrs. Chili. See you later.
