When I run iwconfig I get:

no wireless extensions

How do I get Ubuntu to detect my wireless driver?

Looking at the output from lspci and lsusb, here's the relevant line, from lsusb (so it's a USB wifi and bluetooth device):

Bus 002 Device 002: ID 03f0:171d Hewlett-Packard Wireless (Bluetooth + WLAN) Interface [Integrated Module]

I fear this depends on your wireless hardware. Could you give the relevant part of lspci, or lsusb and dmesg output when you connect the device? – Stéphane Gimenez Aug 27 '11 at 11:02

and i mean, i dont really connect the device, its just in there somewhere. – Hermann Ingjaldsson Aug 27 '11 at 11:37
Ok so the relevant part must be Hewlett-Packard Wireless (Bluetooth + WLAN) Interface [Integrated Module], the device is attached to the usb controller. If ubuntu can't find a driver for it that's bad news. Couldn't find something useful using google, but maybe you should try. – Stéphane Gimenez Aug 27 '11 at 11:58

This seems to be a broadcom-based module. Here's what I've found for it:

apt-get install firmware-b43-lpphy-installer

Suggestion comes from here.

Nice catch. With some luck this might be enough to make it work! – Stéphane Gimenez Aug 29 '11 at 21:46
