OK so I had this problem a while back and its now driving my nuts again. I have a HP DV9005US laptop and the wireless works fine for months. The other day I had to reboot and now no wireless. Amber light on the wireless care, nothing listed if I do an lspci or an lsusb for the broadcom wireless.

The last time this happened I had to reinstall Ubuntu 10.04 and at first the wireless was not working or present then I when out for a while and when I got back I have the new hardware detected. I check for new hardware now and it will not fine the wireless at all.

Does anyone have any suggestions?

I posted this in another section but could not figure out how to move my post. It fits better here.

Tell us exactly what your wireless card is, and if you are logging on at home or in some university or summat!

Right now I am at work and not on the laptop. Its a Broadcom 43XX STA driver that normally is found by the hardware wizard. Its on my laptop at home on my home network and I have been using it for a year plus now. It was working fine awhile back and the same thing happened, after a reboot the wireless stopped working and could not be detected. The lspci and a lsusb do not show any broadcom adapters. I had to reinstall Ubuntu to get it to work.

you may have one of the symptoms.

now its just working again

and now its just working again

And now there is no wireless at all. An lspci does not even show the card. I ran update manager this morning and after the reboot I was DOA again.....

Please help

Try first
modprobe ssb
and see if the card can be found with lspci. Then
modprobe b43
I had a line in modprobe.d for a while
install b43=/sbin/modprobe ssb; /sbin/modprobe b43; /sbin/modprobe btusb (Last for bluetooth)
Beware of 'fast ethernet switching' or similar in the HP bios. If you use your nic, or if the box sets up your nic, the bios turns off the wifi! Unset this option.
Grep the logs to see if it's happy with the firmware

As you will realise, there's a lot of personal pain in there.
