Ubuntu – Wireless doesn’t work on an HP Pavillion DV6000 with an Intel 3945abg

11.10hp-pavilionintel-wirelesswireless

So I just installed Ubuntu 11.10 on my HP Pavillion DV6000 and my wireless will not connect. I been searching all over the Internet for answers so this is my last resort. Nobody can quite figure it out I've heard to get online and do updates cause i dont have a wired connection.

It reads my wireless and ask for passphase and then just cant connect. It keeps popping up every minute or so asking for the password. I have a Intel Corporation PRO/Wireless 3945abg [golan] network controller.

Im new to ubuntu im using a mobile hotspot for my wireless i then went to edit connections found my hotspot then went to the wireless security it is WPA & WPA2 Personal i made sure the passphase is right. The wierd thing is i upgraded from ubuntu 10.10 and the wireless worked fine on this computer. here is my information.

The interesting part of the trace is this:

iwl3945 0000:0b:00.0: Card state received: HW:Kill SW:On

As you also indicated - your rfkill list all results show no hardware/software kill switch issues.

I found this very similar report.

The suggestion was to replace network-manager with wicd (search in software center/synaptic).

There is a bug report for your card on launchpad.

The last entry in the bug report looks promising:

Create a file named config in /etc/pm/config.d/, by doing this:

gksudo gedit /etc/pm/config.d/config

Add this line:

SUSPEND_MODULES="iwl3945".

Save and reboot.
