wlan disappeared

Hi guys,

Something odd happened today, on my first clean boot of the day.

(notebook DELL vostro v131)

Simply, no wlan0 at all.

$ ifconfig -a #shows only eth0 and lo.
$ lspci #shows no wifi at all (should be a Intel Centrino Wireless-N 1030 BGN Rev=0xB0)
$ lshw -C Network #shows only eth0

$ rfkill list #shows nothing

I checked all logs, no error. dmesg, syslog, kernelog, messages... (what else?)

It simply disappeared out of the blue.

I bought a usb wifi dongle to work a bit, and its working fine as wlan2.

But well... What can I do, or check? Maybe try to recreate the interface.

I tried
$ rmmod iwlwifi
$ modprobe iwlwifi
but nothing seems to bring it back.

Also, old dmesg shows (when it was working) that the driver should be:

/lib/firmware/iwlwifi-6000g2b-6.ucode, version 18.168.6.1

I found this driver related to

* Intel Wireless 6005/6205 firmware, version 18.168.6.1
* Intel Wireless 6030 firmware, version 18.168.6.1

Not the Wireless-N 1030. Why it was working on what seemed to be the wrong firmware? Why it disappeared now?

The driver

* Intel Wireless 1000 firmware, version 39.31.5.1
(iwlwifi-1000-5.ucode)

will work with intel Wireless-N 1030 BGN?

How could I test it? Because modprobe do not select the driver.

Thanks any help.
