Wifi trouble on all debian distro's, not on arch distro's - helping a friend

[michel70]

Hi! The weirdest thing. My friend cannot get his wifi connected on debian distro's. On arch distro's he can.

So on all distro's he sees his home network wifi but only on arch versions his laptop actually connects with his wifi. We can't figure out why, can you help?

His laptop is a HP EliteBook 8770w Mobile Workstation with a Intel 82579LM/82579V ethernet network connection

Any help is greatly appreciated.

You may need the "non-free" installer.

What is the output when you put into a Terminal

lspci |grep Network

?
